Annexure-A

Guidelines on Banning of Business Dealings 1. Introduction 1.1 RITES, being a Public Sector Enterprise and ‘State’, within the meaning of Article 12 of

It is not in the interest of RITES to deal with Agencies who commit deception, fraud or other misconduct in the execution of contracts awarded / orders issued to them. In order to ensure compliance with the constitutional mandate, it is incumbent on RITES to observe principles of natural justice before banning the business dealings with any Agency.

1.2 Since banning of business dealings involves civil consequences for an Agency

concerned, it is incumbent that adequate opportunity of hearing is provided and the explanation, if tendered, is considered before passing any order in this regard keeping in view the facts and circumstances of the case.

2. Scope 2.1 The procedure of (i) Suspension and (ii) Banning of Business Dealing with Agencies,

If the Competent Authority, after consideration of the matter including the recommendation of the Investigating Department/Unit, if any, decides that it would not be in the interest to continue business dealings pending investigation, it may suspend business dealings with the Agency. The order to this effect may indicate a brief of the charges under investigation. The order of such suspension would operate for a period not more than six months and may be communicated to the Agency as also to the Investigating Department.

The Investigating Department/Unit may ensure that their investigation is completed and whole process of final order is over within such period.

B. The detailed specifications for the work which are to be carried out by the Contractor are as stipulated here under:- The work should be carried out according to the drawings approved by the RITES and should conform to the provisions of Signal Engineering Manual, Manual for special requirement of Signaling in 25KV A.C. electrified area (RE Manual) and Schedule of dimensions in the section. The Contractor is advised to visit the site of work and acquaint himself fully regarding the site condition before applying for the tender as he should be solely responsible for the proper execution of the tendered work as per specification.

2.0 CABLE LAYLING 2.1 CABLE PLAN:

Cable plan with distribution chart for each cable should be prepared for each station by the contractor leaving adequate spare conductors in each cable as laid down in para 15.3.2 of chapter XV of Part-II SEM conductors on each cable should be left spare upto outer most points and 10% beyond outer most points. Provision should also be made for additional cable conductors required for repeater relays as per 25KV AC electrified section .The necessary approval of layout plan and cable core distribution chart etc., should be obtained from the site engineer before start of cable laying work. Copy of this plan should also be sent to RITES.The Signalling cables must be separated from power cables by a row of bricks between them.

2.0 CABLE TRENCH:

Excavation of cable trench should be made in all kinds of soils including clearing roots of trees, rocks etc., to a depth of 1.0 m and to a width of not less than 0.30 m, proper protection as required by Site Engineer should be provided while crossing power cables, pipe lines, gas lines etc. The bottom of the trench should be leveled and got rid of any sharp materials. Trenches should be straight as far as possible and steep angles should be avoided. Alignment of the main cable route as well as track/road crossings will be indicated in the cable layout plan.

(a) Signalling/Power cables should be laid as close to the track as possible in the

station limit but not less than 3 m from the nearest track centre. The cable track separation distance both within station limits and in the block section generally not to exceed 6 metres. However outside the station limits, the cables should generally be laid at not less than 5.5 metres from the centre or the nearest track.

(b) The steel anchors with clamps should be provided after an interval of 5

meters, fixed and concreted over the laid cable in the trench to avoid the cable theft.

(c) It is desirable that the excavation of trenches is not done in long lengths and

does not remain uncovered overnight. It is preferable that trenches are dug, cable laid and refilling done on the same day.

7 of 94

(d) Wherever rock formation is encountered and trenching cannot be done to a depth of one metre, the trench should be dug as far as possible and protective measures taken to avoid damages of cable as decided by site engineer. The drawing in this regard should be prepared by RITES. Payment of trenching should be made proportionate to the depth of trench and no payment should be made for any extra excavation carried out in the slope and width of the trench. The contractor, who supervises the excavation, should take the shoaring materials ready on hand, so that on banks where ashes or loose materials are encountered, shoaring can be adopted. However, the minimum depth should not be less than 300 mm for laying RCC pipes in hard morrum. Whenever rocky soil is experienced, concreting has to be done for a depth of 150 mm after laying the cables to protect them.

(e) During excavation of the trenches, the earth should not be thrown on the

ballast. The earth should be thrown by the side of the trenches, away form the track. Complete excavated earth should be back filled in the trench after laying the cable and well rammed.

(f) Wherever Power Cables are to be laid alongwith other cables bricks are to be

laid lengthwise approximately, five bricks per metre for separating Power Cables from other Signalling Cables.

2.3 Before the cables are laid, a visual inspection of cable should be made and it

should be tested for insulation and continuity of cores. The insulation resistance of new cable should not be below 500M.Ohms per KM at 20 degrees centigrade. The cable meggering record should be maintained in a register and should be signed by contractor’s representative & RITES official. If there is wide disparity between insulation of different conductors, the conditions of the cable should be thoroughly checked before permitting its use. Bedding and armoring should be inspected to see that there has been no damage during transit or in storage. In case where the wheels are not available or the area is not convenient for rolling the wheels along with route, the drum should be mounted on the axle at one end of trench and cable paved out. It should be carried out by adequate number of men ensuring that the insulation of the cable is not damaged and no kink/twist is formed. In no case should the drum be rolled on the road for laying of cables and the cable dragged on the ground for laying purposes. The cables should be laid gently into the trench and not thrown out under any circumstances. Before laying of cable in the trench, a visual inspection should be adequate for any damage or defect through out its length. Normally, cable laying should be commenced only after the relay room and cable termination box on the route at the respective stations are ready, and the cable should be duly terminated at the relay room/Location Boxes, immediately after the cables are laid. However, if for any reasons the cables are to be laid in advance, special care should be taken to ensure that the coiled cable near the relay room/Location Box is fully protected before and during final termination. The coiled cable should be fully covered with a layer of bricks in its entire length and provided with adequate number of cable markers. On no occasion the ends of the cable should be left unprotected. The cable ends should be sealed with cable compound. All the cable terminals should be sign written with point describing the function.

8 of 94

2.4 Cable laying should commence only after the depth and width of trench, quality of bricks and sand are jointly inspected by the Site Engineer and Contractor’s representative and approved. The necessary record of such approvals should be maintained in a register.

2.5 Cable should not be normally taken over the running tracks at the time of

cable laying by the contractor as this is likely to cause accident to trains and damage to cable. If at any time the cable has to be taken across the track either in full drums or in spread out conditions, it should be done only in the presence of site engineer and also after safety precautions have been taken to post flagmen on all the sides as may be required to stop any train approaching the site of the fouled line. The stationmaster should be informed in writing and a acknowledgement obtained for this work.

2.6 At each end of the main cable/tail cable/power cables an extra coil length of

6 to 8 metres should be kept. 2.7 At the time of commissioning of cables, the insulation values of the cable

should again be checked and the value obtained should not be below 500 M.Ohms per KM at 20degree C. If there is wide disparity between insulation of different conductors, the conditions of the cable should be thoroughly checked before permitting its use. The readings should be recorded in a register called Cable Insulation Record Register. This should be recorded for all cables.

2.8 The Contractor thereafter should supply the completion cable

layout/termination plan and cable route plan showing the distance of cables from the nearest track centre at every 30 M interval and location of location boxes. The distance of location box from nearest track centre should be indicated.

2.9 After the signaling cable/power cables are laid, one layer of country bricks of

size 225mm x 100mm x 75mm approximately, should be placed closely in breadth wise.

2.10 Refilling of the cable trenches with the earth and placing and concreting of

cable markers at an interval of 30 M throughout the cable route and also on either side of track crossings along the cable route should be done. The cable marker should be concreted to a depth of 0.3 M from the top of the cable marker to avoid theft and should be provided with cement coping as per Drg. No. RITES/SIG/GEN/018-98.

2.11 As unscreened signalling cables are used, the necessary arrangements are

made to comply with the instructions issued at Part `B’ of Special requirements of signalling in AC electrified area (1989) with latest amendments.

2.12 Contractor should be fully responsible for making necessary preventive

arrangements to avoid theft/damage to cables, during construction period and also up to handing over of station after commissioning.

On bridges, the cables are to be laid through GI pipe/trough and taken through GI pipe on either ends suitably buried on both sides of the bridges for a sufficient depth so as to meet the bottom of the cable trench, then fixing the pipe in concrete of size 0.5m x 0.5m in both abutments. Separate pipes/troughs should be used for power/signalling cables. Suitable supporting clamps should be manufactured as required by RITES at the rate of 1 clamp/metre depending upon the type of girder. Before fixing GI pipes, perforated holes of 20mm dia should be drilled at an interval of 0.3 Mts. to avoid theft of GI pipes. In case cables/cable is laid through trough, it should be filled in with cable compound/bitumen compound to prevent theft of cables. In theft prone area a special concreting arrangement should be developed in consultation with site engineer in both sides of the bridge from where cable leaves the pipe.

The cable laid on Girder Bridges should be carried out as per Drg No. RITES/SIG/GEN/026-98 in Arch Bridges as per Drg. No. RITES/ SIG/ GEN / 027-98.

4.1 Crossing of Cables from Foot Over Bridge

Wherever it is possible cables should be taken from the foot over bridge for the purpose of track crossing.

The cross protection contacts used in UCR, HR, Circuit should be same i.e.RR back contact in UCR circuit, UCR back contact in the HR circuit.

18 of 94

14.6 INTER CHANGEABILITY OF RELAYS.

As far as possible, the contacts should be so allotted that definite contacts are allotted first and then the deciding contacts so that relays of any contact configuration may be installed.

FOR EXAMPLE :

In QNI relays, (B5, B6) (B7, B8) (C5, C6) (C7, C8) will decide the contact configuration. These contacts are called deciding contacts. If possible these contacts should not be allotted. Should the above contacts is 12F/4B or 8F/8B and post in the contact analysis book.

14.7 PICKING UP OF REPEATER RELAYS :

If repeating relays over and above the relays shown in the approved circuit diagram are required to be picked up, the following sequential proving should be ensured:

1. RPR: Front contact should be proved in UCR circuit and back contact should

16.0 CIRCUIT DESCRIPTION 16.1 Route Request

Route requests are made by simultaneously pressing the signal button and route button located on the control panel. The action of the route request is always conditional upon the down status of the other route requests. Pressing the signal button relay energizes (pick up) the relay GNR. Similarly relay UNR is energized when route button is pressed.

16.2. Route Initiation Route Initiation Reverse Route request; pick up route initiation reverse relay NRR. It is always

conditional upon the down status of the conflicting route initiation. Thus the basic interlocking is ensured at the first stage itself. Route initiation reverse, is automatically released by the train moving for main and shunt signal, but calling on, advance starter needs cancellation after the train movement. This can also dropped by applying the emergency signal cancellation.

16.3 Route Initiation Normal Route initiation normal relay is always picked up with condition of NRR drop &

ALSR pick up. When route is initiated, NRR drop and subsequently route initiation track circuit yellow indication is lit on the concerned first replacement track using TPR pick up.

16.4 Overlap Initiation Reverse Route initiation; pick up overlap initiation reverse relay OVNRR. Overlap

initiation reverse, is released when route initiation reverse is 16.5 Overlap Initiation Normal Overlap initiation normal relay is always picked up with condition of OVNRR

drop & OVSR pick up. When overlap initiation reverse relay is picked up subsequently OVNNR DROPS.

16.6 Point Initiation (NLR/RLR) Route Initiation, Initiates points operation on the route and overlap sections.

Point initiation, NLR/RLR is released when point ordering WNR/WRR is picked up and point initiation repeater relay NLPR/RLPR is released when point detection NWKR/RWKR is picked up. Normal point Initiation pick up the relay NLR & NLPR and reverse point initiation, pick up the relay RLR & RLPR.

16.7 Point Chain (WWR) Due to power feeder constraints, all the points in the route and overlap are not

switched on at a time. They are made to switch on in succession. Pont initiation, pick up the first point chain relay WWR, second point chain relay WWR pick up after the first point ordering WNR/WRR pick up. The first point detection is not required, to order the second point.

16.8 Point Order (WNR/WRR) Point is usually ordered by route request using point chain relay. Point may

also be ordered by manual point requisition. By route request or manual

20 of 94

request normal point order, pick up the relay WNR and reverse point order, pick up the relay WRR. The point order is always conditional upon the free status of the point. Normal point operation through manual request or route request is always conditional upon the free status of the point track and axle counter. In case of any failure in the track circuit or axle counter point is ordered through emergency point operation. Point order is released, only when point is initiated to opposite position. Once point is ordered, point normal/reverse flash indication will come up to detection comes from field. Once detection comes, point normal/reverse steady indication appears.

16.9 Route Check Once the points NWKR/RWKR are picked up in the required condition, then

the route setting is completed [UCR (↑)].This is conditional upon all the controls needed to clear an aspect except track condition[CHNR (↑),LXNR(↑),KTNR (↑)]. In Route check relay UCR, second stage interlocking is achieved through proving of down status conflicting UCRs with same point setting & same signal post other signal. Route check relay UCR, is released when route initiation relay NRR is released by the train movement or by applying the emergency signal cancellation.

16.10 Route Lock After route is checked, it is locked by dropping the route locking relay ALSR.

Once ALSR is dropped whole route set yellow indication is lit. Locked route gets release only after ensuring the following conditions.

• The signal control functions are normal. This is achieved by proving of

concerned UCR HR, UR and DR drop. • The signal is ON. This is achieved by proving of concerned HECR,

UECR & DECR drop. • The train has passed the route sequentially. This is achieved by

proving of pick up of UYRs and back lock tracks. OR

The route cancellation. This is achieved by proving of JSLR and JR will pick up only after 120 seconds of cancellation, provided all the back lock tracks are picked up. Respective route release & up or down route release indications are lit up to 120 seconds.

Bobbing of track circuits and dropping of any one of the associated relays

should not drop the ALSR. This achieved by providing a self stick path. ALSR drops only when UCR picks up. After ALSR picks up, whole route set yellow indications and route release indications disappear.

16.11 Overlap Lock Once route checking relay UCR picks up, overlap locking relay OVSR will drop

immediately and lock the overlap section. Once OVSR drops, overlap track circuit yellow indications appear. Due to the train movement, back lock track is dropped and subsequently the train arrives to the berthing track. Now ALSR & TRSR/TLSR will pick up and release the route section but the OVSR remains drop. When the train pass the ahead signal sequentially, OVSR pick up and release the overlap section. If the train has stopped on berthing track for some more time, OVJSLR pick up immediately and subsequently OVJR picks up after 120 seconds. Now OVJR picks up OVSR which releases the overlap section and also overlap track circuit yellow indications disappear.

21 of 94

16.12 Automatic Route Release

The locked route for a train movement gets release only after ensuring that the train has arrived on proper signal in proper direction and the track circuits have been sequentially actuated by the train. This is registered by the setting of sequential proving logics of UYRs. The UYRs pick up proving are used to pick up ALSR in the normal route release path. The UYRs are picked up in a pre-determined fashion to ensure the sequential operation of tracks by a train.

16.13 Emergency Route Cancellation It a route is to be cancelled, which will drop the particular NRR, UCR, HR and

subsequently signal goes to danger. Then SM applies route cancellation, this will pick up EGNR which subsequently pick up JSLR immediately and JR after 120 seconds. JR picks up ALSR and ALSR picks up TRSR/TLSR & OVSR immediately. Thus the route is cancelled completely and route set indications disappear.

16.14 Point Lock Point lock logic WLR pick up indicates that the point is free. Locking relays

ALSR, TRSR/TLSR, OVSR pick up are used in WLR logic. The freeness of the point from route setting/overlap setting is ensured by proving locking relays pick up of all the signals which are leading over the point.

16.15 Track Stick Track stick logic TSR, is used to ensure One Train movement on One Signal

clearance. Each signal has TSR logic with the signal number. TSR relay is normally picked up through the signal replacement track pick up and NRR, UCR, UR and HR drop proving. One this TSR picks up, it gets a stick path by passing NRR, UCR, UR and HR drop proving. When the route is initiated NRR picks up, even then TSR remains pick up through its and HR drop proving. When the route is initiated NRR picks up, even then TSR remains pick up through its sell stick path. When the train passes the signal and occupies the replacement track TSR drops. After this train clears the replacement track, TSR cannot pick up till such time the respective route NRR drop. This logic ensures that after the passage of the train, the signal cannot re-clear automatically.

16.16 Crank Handle Control Crank handle is kept locked in an EKT and crank handle logic CHNR pick up

normally. Once CHNR picks up crank handle KEYIN steady indication appears. When the crank handle is to be extracted because the point cannot be operated electrically, station master applies transmit, CHRR will pick up provided no signals over the point controlled by this crank handle group are being cleared. Once CHRR picks up crank handle KEYIN flash indication appears. CHRR enable the lock to be released and the crank handle key can be taken out. Once the crank handle transmit is applied and CHRR pick up. CHNR drops. CHNR drops. CHNR dropping will prevent any concerned signal being cleared and any concerned point being operated.

Once crank handle is taken out and points are operated manually, the crank handle can be restored back. Now crank handle KEYIN flash indication appears. After seeing the KEYIN flash indication, station master applies release control. Now CHNR picks up and crank handle KEYIN steady indication appears and one circuit becomes normal.

22 of 94

16.17 Level Crossing Control For the train movement over the level crossing, the level crossing gate is

closed and the key is deposited in the EKT at the location of the gate. This will pick up LXLR. After getting gate closed flash indication, station master applies release control. This will pick up LXNR. Once LXNR picks up, gate closed steady indication appear. LXNR will ensure that gate closed and locked, this is proved in UCR and HR circuit.

Station master initiates the route. LXLR drops when the route is initiated and subsequently gate locked indication appears. After the train movement, using pick up of concerned ALSR/OVSR/TRSR/TLSR the LXLR picks up. Once LXLR picks up gate locked indication disappears. Now station master will apply transmit control. This will pick up LXRR. Once the transmit is applied LXRR picks up and LXNR drops. This will pick up LXRR. Once the transmit is applied LXRR picks up and LXNR drops. This will ensure that no signal can be cleared which involves movement over this level crossing. Once LXRR picks up gate closed flash indication appear. Now LXRR with pick up slot relay at location and gate man will extract the key.

Once gate is closed, GFRR also comes from the field in addition to the KTINPR. GFRR is proved in HR when GFRR is made available from field as vital input, GFKE indication will appear in the Panel/VDU. This GFRR is to be put back to normal (dropped using hand lever near the gate) to raise back the concerned UP & DN signals to `ON’ in case of emergency.

16.18 Signal Control; The following conditions are required to clear a signal i.e. to pick up HR of a

concerned signal. • Initiation of route and overlap. This is achieved by proving of NRR,

OVNRR pick up. • Checking of route and overlap. This is achieved by proving of UCR pick

up. • Locking of route and overlap. This is achieved by proving of ALSR,

TRSR/TLSR & OVSR drop. • Detecting & locking of route and overlap points. This is achieved by

proving of concerned points NWKLR/RWKLR pick up. • Unoccupied condition of Route and overlap section tracks. This is

achieved by proving of route and overlap tracks pick up. • Crank handle key in and locked is achieved by proving CNHR pick up. • Level crossing closed is achieved by proving LXNR pick up and ground

frame reversing GFRR pick up. • Siding point set to normal and key is in and locked is achieved by

proving NKR and KTNR pick up. • One train on one signal. This is achieved by proving TSR pick up. • Concerned cancellation timer is normal. This is achieved by proving of

JBPR pick up. • Ahead signal aspect is given if any. This is achieved by proving ahead

signal ECPR pick up. • Route indicator is lit before signal is taken off for turnout. This is

achieved by proving UR & UECR pick up. • Block control is available for last stop signal. This is achieved by

proving LCPR pick up.

23 of 94

The caution aspect of a signal is controlled by relay HR. Attention aspect of a signal is controlled by relay HHR Clear aspect of a signal is controlled by relay DR. The ON aspect maintained through down proving of HR. Signal indication is given through respective lamp proving relay ECR. Common OFF aspect indication is provided for all OFF aspects viz. HG, HHG & DG.

16.19 Calling On Signal Control Normally when any track circuit fails, a calling on signal can be used to receive the train. Calling on signal will be cleared only after satisfying the following conditions.

• All points in the route of the calling on signal are correctly set and

electrically locked. • The main signal above the calling on is at ON. • The train has come to a stop at the foot of the calling on signal. In order to prove that the train has come to a stop, a short approach track circuit is used. The calling on route in checked by C1UCR. C1UCR picks up after getting point detection. Now ALSR drops and hold the route. Now whole route set yellow indications appear. Calling on signal clearance timer C1COJSLR will pick up only when C1UCR is pick up, approach track occupies and main signal above the calling on signal is at ON. Now AJKE indication will flash upto 120 seconds. After 120 seconds time delay, C1COUR will pick up through JR and the signal C1HR will be cleared. Common ALSR is used for main and calling on signals. For calling on route release manual cancellation is always required. If sequential proving relays UYRs are picked up route will be released by applying signal cancellation, immediately. If sequential proving relays UYRs are not picked up the route will be released only by applying route cancellation, after 120 seconds time delay. Upon calling on signal cancellation by the station master, C1A/B NRR and C1UCR will drop. Once calling on route cancellation is applied. EGNR picks up and this will pick up JSLR. This is common JSLR used for Main signal emergency cancellation as well as for calling on emergency cancellation. Now AJKE indication will flash upto 120 seconds. After 120 seconds time delay, ALSR will pick up through JR and the route will be released. Now whole route set yellow indications disappear.

17.0 Alarm Alarm logic is available for signal failure, point failure, point failure and

button stuck. 17.1 Signal failure alarm and indication

In signal failure alarm. Whenever any of the signals becomes blank due to signal lamp fusing, signal failure alarm will come. MFFR picks up through any one of the ECRs pick up of all the signals proved in series. Hence this relay is normally picked up. This is made slow to release 10 seconds, to prevent dropping during aspect change over. If any signal becomes blank, MFFR drops and alarm rings. Alarm will continue till such time it is acknowledged by the station master and MFFMR is picked up. The visual indication will appear as soon as MFFR drop. This indication remains till such time the failure is rectified and MFFR pick up.

24 of 94

17.2 Point failure alarm and indication

In point failure alarm, whenever any of the points becomes fail, point failure alarm will come. PTFAIL picks up through any one of the NWKR/RWKR pick up of all the points proved in series. Hence this relay is normally picked up. This is made slow to release 20 seconds, to prevent dropping during point is running. If any point becomes fail, PTFAIL drops and alarm rings. Alarm will continue till such time is acknowledged by the station master and PTFMR is picked up. The visual indication will appear as soon as PTFAIR drop. This indication remains till such time the failure is rectified and PTFAIL pick up.

17.3 Button stuck alarm and indication In button stuck alarm, whenever any of the following button becomes stuck, button stuck alarm will come. NNCR picks up through GNCR, UNCR & WNCR high status. GNCR picks up through down status of all signal buttons, UNCR picks up through down status of all route buttons and control buttons & WNCR picks up through down status of all point buttons, UNCR picks up through down status of all route buttons and control buttons & WNCR picks up through down status of all point buttons. Hence NNCR but is normally picked up. This is made slow to release 10 seconds, to prevent dropping during button operation. If any above button becomes stuck, NNCR drops and alarm rings. Alarm will continue till such time it is acknowledged by the station master and BHAR is picked up. The visual indication will appear as soon as NNCR and GNCR/UNCR/WNCR drop. The indication remains till such time the failure is rectified and NNCR pick up.

17.4 Block Signaling The Block signal is controlled by station A and also by Double Line Block

Instrument at station B. After getting Line clear at station A the Block signal can be cleared. As soon as the train occupies the track circuit in advance of Block signal, it is replaced to ON and train entering indication comes at station A. Station master at A given train entering signal on the bell plunger to the B station master. B station master turns the handle to TOL position. The block handle at B is now locked at TOL position.

Station master at B clears Home signal for receiving the train. When the train reaches the block clearance point in advance of the Home signal, door lock coil is released and station master turns the handle to Line closed position. Station master at A after observing the Line Closed indication on the block instrument, applies Block signal cancellation.

17.5 LVV Reset

IThe block sections are provided with Last Vehicle Verification using digital axle counter. If after train clear the block section, the digital axle counter ACPR fails to pick up, the LSS and IB signal cannot be cleared. In such a case the reset of digital axle counter will be carried out. Due to inherent property of digital axle counter, ACPR will pick up only when subsequent train has been passed on paper clearance and equal counts have been received.

39.1 TESTING OF OUTDOOR GEARS Testing of outdoor gears consists of: - a) Signals b) Motor operated points c) Track circuits d) LC gates (Interlocked) e) Sidings f) Slots

39.2 COMMISSIONING OF PANEL

Commissioning of panel consists of: - a) Testing all signals from panel and correspondence of b) Checking the correspondence between the points and their panel

indications.

c) Checking the correspondence between the track circuits and its panel indications.

d) Testing of sidings, its electrical transmission of EKT, panel indications.

e) Testing of LC gates, its electrical transmission of EKT, panel indications.

39.3 TESTING OF RELAY INTERLOCKING ENERGISATION OF RELAYS BY

CONNECTING SIMULATION PANEL: 39.4 For major yards, it is preferable to energise relays, circuitwise and sheetwise,

since it involves number of routes and parallel movements. For way station, it is preferable to energise the circuit, route wise. Before taking up the above energisation, the following work should be

completed. a) Wire to wire bell-test of all sheets before soldering and after soldering. b) Plugging of all relays as per contact configuration.

Before plugging of relays, all fingers are to be checked. Any finger found loose or not properly hooked is to be set right.

41 of 94

c) Power supply arrangement with batteries. d) Connecting the simulation panel.

i) It should be possible to control all TPRs, NWKRs/RWKRs, CHLRs,

KLCRs, LXCPRs etc., from the simulation panel by energising all the relays.

ii) It is desirable to have the simulation panel adjacent to control panel so

that the panel indication can be observed simultaneously while testing. 40.0 CONNECTING SIMULATION PANEL Simulation panel consists of two Boards:-

A.) BOARD NO. 1:-

It depicts the yard (painted) with points, track circuits, LC gates and slots. Switches are fixed on the boards to simulate the conditions of the points, track circuits, interlocked LC gates, slots etc.

Track circuit switches are fixed on the track. Point control switches are fixed nearer to the points, for small yards. For major yards the switches are grouped as point switches and track circuit switches. Functions requiring ON and OFF switch (with make and break facility i.e. two wires only) with facility to pick up a relay in one position and drop the same in other position. Example: Switch OFF - Track Down - TPR dropped. Switch ON - Track pick up - TPR picked up. For controlling the following function the above type switches should be used: - i) Track circuits ii) Siding point iii) Crank handle iv) Slot v) LC gate

Points require ON and OFF switches with facility to pick up conflicting relays (i.e. NWKR and RWKR) in two positions. (These switches require three wires).

B.) BOARD NO. 2:-

To simulate the signals the following bulbs are used as dummy loads for the ECRs to pick up and also to observe the aspect of the signals during testing. ON aspect 110 V 40 W OFF aspect 110 V 25 W Route aspect 110 V 75 W (Jn. type Route Indicator) C.) Wiring simulation panel to the relay room side wiring at MDF.

42 of 94

Disconnect all the links on cable termination rack. Wires from the switches are connected to the relay room side termination. Similarly the wires from simulation panel board No.2 consisting of lamps are connected to the relay room sides termination. Multicore 0.6mm dia. cable is used for wiring the simulation boards. To reduce the voltage drop, more conductors are used for supply taken to the test panel and also to the negative since common return is used.

41.0 TESTING AND COMMISSIONIONG OF OUTDOOR EQUIPMENTS 41.1 Cable meggaring and pairing up of conductors should be done.

41.2 All the power cables should be made through and power supply should be

extended to all locations.

41.3 After the power cables are energised, check up each limb of the power cable whether any earth fault exists using multimeter. Thus will indicate whether any cable conductor is faulty (i.e. earthed).

42.0 TESTING OF SIGNALS

i) Signals should be initially tested from the LOC box to attend to minor troubles of bulb holders, wiring etc.,

ii) All the aspects should be checked by giving 110 V AC feed from Loc.

Box and then the test should be repeated by giving feed from Relay room CT rack. This test should be done for each aspect, route and pilot lamp of shunt signals.

iii) Care should be taken to ensure that no train is approaching during this

test to avoid misleading information to drivers.

iv) Ensure that signal number plate is provided and unit back door is fastened and locked properly. Door locking is very important to prevent sun rays falling on to lenses to give phantom indications.

v) Focus the signal aspects, record the aspect voltages and ensure that it

is within the permissible limit (90% of rated voltage of the bulb).

43.0 TESTING OF POINTS

I.) POINTS

Should be tested first locally from the location box when point contactor unit kept in location. Before commencing this test, ensure 110 V DC, 24 V DC are available in location box. If it is cross over point, it is preferable test one by one and then test both at a time.

II.) SIEMENS POINTS CONTACTOR UNIT

After the point operation is completed, drop RWCR, WCR by disconnecting the supply.

ii) Check up whether outgoing RWKP supply is available in location box.

For reverse to normal operation, change the polarity on W1 & W2 and check.

Care should be taken to check whether correct wiring is done with regard to polarity.

iii) Check up whether the cross protection wiring is done on the electrical detector.

iv) Check up whether snubbing is effective in case of GRS, 5E point machine.

v) The following tests should be carried out on Pt. Machines:-

a) Obstruction test b) Detection contact break test. c) Out of correspondence test (in case of cross over point). d) Track locking test (to be done when operated from panel). This test is to

be done for both N to R and R to N operations. e) Whether point can be hand cranked with interlocked crank handle. f) Check the correspondence between point position at site, both the ends

in case of crossover and NWKR / RWKR in relay room (to be done when tested from panel).

44.0 TESTING OF TRACK CIRCUITS

i) All the track circuits should be energised and outgoing TPR voltage checked.

ii) Check whether cross protection wiring is done for TPR circuit. iii) Shunt the track circuit at various places on the track and check whether

the track relay drops every time it is shunted. (Especially near fouling marks).

iv) Check the correspondence between TR and TPR in relay room.

44 of 94

v) Track circuit should be adjusted properly and readings recorded. TSR value should be recorded.

vi) Check whether the track circuit is protecting the fouling point. vii) Ensure that atleast one polarity rail is in series connection. viii) Check up in put AC voltage to the track feed charges is sufficient and

battery is getting charged.

44.1 Check up the interlocking of L.C. Gates, siding points.

a) Check up for the proper functioning of electrical transmission of key transmitters.

b) Check up the panel indications.

c) Connect magneto telephone communication between SM and LC

gate/siding.

d) Ensure that respective signals cannot be taken off if LC/siding controls are not available with SM (i.e. on panel).

e) Ensure that when the signals are taken off, respective LC gate/siding

key cannot be extracted from the EKT.

45.0 TESTING OF SLOT CIRCUITS

Wherever end panels are available, inter cabin slot circuits should be tested. Slot circuits can be tested similar to that of signal HR circuits.

SLOT CIRCUIT RELAY SIMILAR RELAY IN HR CIRCUIT a. SLRR RR b. SLUCR UCR c. OVSR ASR d. OVYR HR

Negative tests, approach-locking tests, back lock/route holding tests, cancellation of slots should be tested similar to that of any signal in the yard as given in table of control.

46.0 COMMISSIONING OF PANEL Check up all signal aspects by directly feeding from cable termination rack

(110 V AC). Check up operation of points from C.T. rack and check whether NWKR/RWKR

incoming feed is available (by connecting 24V DC to W1, W2, W3 & W4 as explained earlier).

45 of 94

Check up the incoming feed of TPRs in the C.T. rack. The above checking will confirm the pairing of cable conductors.

Remove the wiring connection of simulation board on cable termination rack

and make through the links of all TPRs, WKRs and signal circuits. First test the points from panel individually and conduct all tests discussed

earlier including track locking test, correspondence between point position and NWKR/RWKR in relay room.

Check whether all TPRs have picked up and check up the panel indication by

individually by dropping each track circuit correspond correctly. Check whether all other required relays viz., CHLR, LXPR, KLCR have picked

up.

Test all the signals from panel.

Check the correspondence between relay from and signal aspects, which is most important. For checking the aspect s of home signals, distant signals, staff (not below the rank of Site Engineer) should be deputed to site with walkie-talkie or Magneto telephone and check the correspondence.

Remove the signal bulb at site of every aspect and check whether indication disappears on the panel and ECR drops in the relay room.

Open all the registers and make entries of counter numbers before handing over to operating staff.

47.0 THE FOLLOWING REGISTERS SHOULD BE HANDED OVER TO OPERATING STAFF.

a) Relay room key register, b) Route cancellation register, c) Crank handle register, d) Axle counter reset register, e) Diesel oil consumption register (Generator working register).

existing telecommunication facilities, to work out the exact requirement of the 6

quad and derivation/PIJF cable and materials required for different items of

work, finalize all the drawings and site plans required for the execution of the

work and also to examine the details collected during preliminary survey and to

affect necessary changes/modifications, if any.

2.6 MAIN ITEMS OF WORK

The following are main items of work, which should constitute the detailed survey: -

2.6.1 Closely examine the proposed cable route and prepare cable route plans.

68 of 94

2.6.2 Sighting of areas for loading / unloading of cable drums and siding facilities for the EMTs (Engineering materials, trains for the project ).

2.6.3 Preparation of route charts for derivation, PIJF cables with the size and length of the cables for each tapping and termination arrangement.

2.6.4 Estimating of requirement of special cable lengths of cables for long girder bridges.

2.6.5 Deciding location of each joint and preparation of a joint schedule.

2.6.6 Determining earth resistively measurement of each cable section along the proposed cable route.

2.6.7 Working out the exact length of derivation, PIJF cable required.

2.6.8 Preparation of material schedule required for different protective works.

2.6.9 Arranging isolated telephone circuits to be provided in the cable.

2.6.10 Investigation on special problems of the section and finding out proposed solution thereof.

2.6.11 Examination of chemical composition of soil to see whether any special precaution are to be taken to protect cable from soil corrosion.

2.7 FINALISATION OF CABLE ROUTE PLAN.

The following are the guidelines for finalizing the route and preparation of the cable route plan:-

2.7.1 Prepare the “5 Km. charts” as explained above showing the relevant chainages and details in the “5 Km. charts”.

2.7.2 Actual measurement by 30M steel tape or chain along the route is necessary only in case of important locations to be terms as “special terrains” for example, approach to repeater station/Cable hut, long bridges, big yards, sharp diversions in the cable route from its parallel course along the main railways track due to obstruction, cutting etc.

2.7.3 Inspect and decide the portions of route falling in category of “special terrains” i.e. where actual longitudinal measurement is necessary.

2.7.4 The remaining portions of the route i.e. other than the portion decided as “special terrain” are to be terms as “straight runs”. Actual chaining along the route is not necessary for such ‘straight runs’ and these can be marked on the ‘5 Km. charts’.

69 of 94

2.7.5 For the ‘straight runs’ on the cable route an allowance of 3.5 % of the drum length should be made for the contours, joining etc. and each drum length should be considered to cover a route of 0.965 x cable drum length.

The cable route should be started from a repeater cable hut station. Actual measurement along the route should be done by means of a 30M steel tape for a few drum lengths up to a convenient point along the main line where from the distance along the route may be reckoned from the Plan. A termination allowance of 5M cable inside the repeater station/cable hut building should be made, in addition to a length of about 10M being kept in a pit just put side the building.

2.7.6 It should be ensured that both “special terrains” should consist of full drum lengths, so that the position of joints (other than ‘T’ joints) is fixed without difficulty in both cases.

2.7.7 Actual measurements of the separation distance from the center line of the reference should be made where necessary. In case of special terrains, the separation distance at some points on the route may also have to be reckoned from some other permanent structures depending upon the site conditions.

2.7.8 The separation distance of the cable route from the nearest track on the “straight runs “ should be 10M. The deviating from this standard separation of 10M should be kept to the minimum and as soon as any obstruction has been negotiated, the route should again follow this standard separation distance. It is desirable from the point of view of calculating the induced voltage that the uniformity of the separation is maintained for the maximum possible length of the main cable route.

2.7.9 Separation distance should be marked on the “straight runs” portion of the cable route plan (5 Km. chart) at intervals of not more than 250 M. In addition, the separation distance at points of change in the cable route such as diversions, track crossings, approaches to bridges, culverts, etc. should invariably be marked on the cable route plan in such a way as the intended cable route is clearly defined for “special terrain” the separation distance should be marked at as close intervals as is considered necessary depending on the site conditions.

2.7.10 The route should be decided by walking along the track. On long stretches “straight runs” a push trolley moving slowly may be used. The trolley should be on the track closes to the proposed route.

2.7.11 Actual measurement should be made for the protective works required for the cable passing over the culverts, under tracks, over long girder bridges, level crossings, rocky areas, under the bed of culverts.

70 of 94

2.7.12 Once the cables are laid the actual length of cable as per the printed marking on the cable is required to be indicated at every kilometer of cable route, at diversions, crossings, approaches of bridges and joints for quad cables.

2.8 FINALISATION OF TAPPING DIAGRAM

2.8.1 The survey team should visit each location such as cabin, SM,s offices, Loco sheds, cabins, gate lodges, etc. and verify the details collected during the preliminary survey of all the existing telecommunication facilities, and additional telecommunication facilities to be provided.

2.8.2 The position of each tapping should thus be finalized and a final tapping diagram prepared.

2.9 ISOLATED TELEPHONE CIRCUITS

It is necessary that all the telephone circuits such as isolated quarry sites, gate lodges, etc. are taken note of and provision made for transferring the overhead alignment into cables wherever considered necessary.

2.10 LENGTH OF 6 QUAD CABLE

The cable length is worked out on following basis to arrive at the locations of

the straight joints:-

a) Route length as per actual measurement plus contour allowances of 2.5%.

b) Extra length for track crossing including 2.5M loop on each side etc.

c) Extra length on approach/crossing of the bridges and culverts as per measurement in the detailed survey.

d) 10M of cable to be kept on either side of major steel bridges and 5M on minor bridges.

e) At every joint a loop of 10M on either side.

f) In cable hut a loop of 10M in the cable pit.

2.11 SIZE & LENGTHS OF DERIVATIONS/PIJF CABLE AND ROUTE CHARTS

The derivation/PIJF are required to laid from ASM’s office to cabins, enquiry &

other operational points, depots, supervisor’s residence etc. for extending

control tapings. The plan and requirement of different sizes PIJF/derivation

cables shall be suitably worked out. As for as possible derivation/PIJF cables

71 of 94

shall be laid in the trenches for main telecom cables and branched off at

suitable locations.

2.12 PREPARATION OF JOINT SCHEDULES

The details of type and number of joints in main 6 quad cable is required to be worked out based upon the, obligatory locations, LC gates etc. The typical drum lengths of 6 quad telephone cable is 1 Km. and therefore, it shall generally be possible to combine straight through joints.

2.12.1 No isolation transformer is considered necessary for LC gate & other location telephones up to a distance 7.5 Km. on 6 quad telephone cables.

2.12.2 The jointing schedule shall be made as straight-line diagram indicating the locations of various joints with reference to chainages. The length of 6 quad cable from leading cable hut /ASM’s office shall be specifically indicating taking into account the factory printed markings on the cables.

2.12.3 The requirement of termination boxes for cables at various locations shall be worked out.

2.13 MATERIALS REQUIRED FOR PROTECTIVE WORKS

2.13.1 The cables are meant for direct burial underground and no special protection is required in plain and normal territory. For building, masonry platforms, culverts,

crossing of tacks, level crossings and roads etc. special protection works are specified in the following drawings: -

i) For girder bridges, G.I. pipe / HDPE pipe medium grade with ISI mark as per drawing.

ii) For cable entries to cabins, ASM’s office etc. through GI pipes Drg.

iii) For cable terminations in ASM’s office

iv) For cable jointing pit the cable trench

v) For laying cables over arch bridges brick channeling Drg.

2.13.2 Actual measurement should be made for the length for which special protection is necessary and the requirement of materials for the protective works should be worked out. The requirement of materials based on the actual protective works should be shown in the cable route plan at the appropriate place.

2.14 COMMUNICATION ARRANGEMENT IN MAJOR YARDS & STATIONS

72 of 94

In big yard and major stations involving large cabins/Depot/Tapping points, it

may not be practicable to lay independent derivation cables for various

locations. Therefore one main cable shall be laid to transverse in a zigzag way

through the yard involving frequent tapping points. Lead sheath derivation, 6

quad or higher size PIJF cable may be laid for this purpose. The circuits

should preferably be tapped through V.F. transformers.

2.15 SPECIAL PROBLEMS OF THE SECTION:

2.15.1 Certain Sections may present special problems such as presence of chemically active soils, marshy areas deep cuttings in the rocky areas, requirement of specially constructed platforms for distribution of cable drums along a high embankment etc.

2.15.2 Approaches to large bridges may also present special problems due to high embankment as well as deep ravines.

2.15.3 The survey party should inspect and report to Engineer in- charge such problems at the outset so that suitable solutions can be worked out.

TECHNICAL SPECIFICATION AND INSTRUCTIONS FOR TRENCHING AND LAYING OF UNDERGROUND TELECOMMUNICATION CABLE AND PROTECTIVE WORKS

3.1 SCOPE:

This chapter deals with the specifications under which the various work for trenching & laying of underground telecommunication cables coming under the purview of the contract are to be executed by the contractor.

3.1.1 SUPPLY OF TAPPING & ROUTE PLAN

Cable route plan, Tapping plan and jointing schedule for jointing of cable will be prepared and supplied by the contractor in consultation with the engineer before the commencement of the work. This shall give a fairly accurate idea of the number & locations of the various tapings required on various circuits and the quantities and type of various equipment to be fixed, wired and commissioned. These shall be got approved from the Engineer.

3.2 INSTRUCTION FOR EXCAVATION & BACK FILLING OF TRENCHES

3.2.1 The representative of Engineer in charge of the work will mark the route of the cable in white chalk or lime as per the tapping and route plan and the instructions given to him by the Engineer, not with standing the cable route shown in the tapping and route plan to meet the requirement of local conditions at site, if any and as required shall be taken by the contractor to be final. The contractor shall be present at the time of marking and he shall furnish to the engineer's representative required quantities of lime, rope labour etc. for carrying out this work. The marking will be given on the track side of the trench at a distance approx. one meter away from the center line of the trench. In the difficult terrains such as water-logged areas, the position of the cable route will be specified by off sets from the center line of the nearest track.

3.2.2 Trenches for telecommunication cable shall normally be done as per Drg. Digging to a depth of one meter or as specified in schedule of work. The width of the trench shall be 300 mm. In places where underground pipes, electric

74 of 94

mains etc. come in the way, trenches deeper than one meter shall be dug as necessary and HDPE pipes shall be placed to protect the telecom cables.

3.2.3 Metal led, macadamized, concrete and stone paved roads shall also be cut to a depth of at least one meter. The cable shall be laid through HDPE pipe as per Drg. No.RITES/LKO/PO/TELE-1. The road surface shall be restored to original.

3.2.4 The bottom of the trench where the cable is to be laid shall be thoroughly prepared and shall be free from any stones. The bottom of the trench shall be horizontal and shall in no case be undulating. When the cable bed changes from solid to soft surface or from the bridge to soft soil, tamped fill at the transition point shall be provided so that cable is not pressed against the edge of a hard surface.

3.2.5 In the entire cable route brick covering is required to be provided as per the approved 'Tapping route plan' or as per the instruction by Engineer the contractor shall arrange supply and distribution of well burnt bricks of standard size at site along the excavated trenches and after uniformly covering the cable laid in the trenches by Stone-free sieved soil up to 50 mm height above the cable, he shall arrange to place the bricks flat and position them breadth wise so that on an average, 8 bricks shall be laid in a meter length.

NOTE: In order to be certain that the full requirement of bricks has been arranged by the contractor for placing on the top of the cable to be laid on any day he shall arrange to spread the bricks side by side on the top of the trenches before the depth of the trenches are inspected by the Railway representative.

3.2.6 The back filling of trenches shall be done by tamping and consolidation the excavated soil in layers of 15-20 cm at time. All the soil that is excavated shall be put back to the trench and care shall be taken in consolidation to ensure that the back filling does not suffer any sinkage in monsoon. The left out earth if any within station limit has to be thrown out from Railway premises by the contractor at his own cost.

3.2.7 Wherever the Engineer's representative considers it necessary to adopt shoring, the contractor will be required to adopt shoring for which the contractor shall have sufficient quantities of shoring material on hand. Where the direction of trench has to change, it should be done in a gentle curve of not less than one-meter radius and not at sharp angles.

3.2.8 Places where back filling is not done properly are likely to get water logged with the first rains after completion of the work, the contractor and engineer's representative will inspect the entire section soon after the first monsoon and the contractor will arrange to set right such areas.

75 of 94

3.3 TRACK CROSSING

All cables crossings across railway tracks shall be done in G.I. pipes, taking the cable through these pipes. The contractor shall track by excavating trenchless track upto required depth where ever necessary to cross the track. Two G.I. wire of 10 SWG size shall be threaded through G.I. pipe, one to pull the cable one for future use.

3.4 ROAD CROSSING

3.4.1 When crossing road ways it is necessary to lay the cables in such a manner as to avoid the necessity of handling the cable sharply and minimize the excavation of road surface as far as possible. Where cable is laid in surfaced trucking the trucking alignment should be curved down to the pipes and proper bricks or concrete joint should be made between trunking and pipe

3.4.2 The crossing of main roads often involves difficulties especially if traffic is heavy, precautions to avoid accidents to workmen, pedestrians and vehicles should be taken. On minor roads, which can be temporarily closed to traffic, it is possible to open up and cross the entire width of the road. Pipes should be installed quickly in the cutting, which is then filled in there by reducing to a minimum time for which the road is closed.

3.4.3 Track crossing and crossing at busy roads should be done through trenchless method according to schedule of work.

3.5 CABLES OVER STEEL GIRDER BRIDGES

3.5.1 Where the cable has to cross the girder bridges, the cable shall be protected with G.I. pipe/ HDPE pipe fitted on the girder bridges with suitable clamps without drilling holes in the girders.

3.5.2 When laying cable on long bridges, the question of longitudinal expansion caused by temperature differences should be taken into consideration and suitable cable loops should be provided at the pillars of the bridges.

3.5.3 The laying of the cable on the bridge is to be done with much care and planning. It is necessary that the cable drum to be laid on the bridge is inspected and tested thoroughly so that damaged cable is not installed.

3.5.4 As the laying involves movement of large number of staff over the bridge the line should be blocked and flagman posted on either side on a double line near which the cable is being laid should be blocked but care should be taken to see that staff are aware of this and measures taken to prevent staff from staying on to the unblocked line.

76 of 94

3.6 CULVERTS & ARCH BRIDGES

3.6.1 Wherever possible the cable shall be laid under the bed of the culvert through HDPE pipes. Similar arrangement shall be provided for taking the cable in water logged areas and drains.

3.6.2 In case of wet culverts or unfriendly terrains where it is not possible to lay cable under the bed of culverts the cables may be laid over the culvert in GI pipes/ HDPE pipes.

3.6.3 The protection of cable on Arch bridges and approach to culverts & bridges should be as per Drg Number

3.7 CABLES IN MARSHY AREAS

3.7.1 In marshy area where it is not possible to divert the cable route the cable shall be suitably laid and protected as per decision of Engineer depending on site condition, like laying cable in RCC pipe/ HDPE pipe supported on masonry pillars/ iron channels etc.

3.8 LAYING OF MAIN/ DERIVATION CABLE IN MASONARY BUILDINGS & CABINS

3.8.1 Derivation cable/PIJF will have to be led inside any masonry building such as cable hut, ASM's room at a depth of 0.75 M by cutting the masonry structure of the wall. After the cable has been laid inside the masonry wall the floor inside shall be duly repaired and plastered.

3.8.2 When a derivation cable has to be taken and terminated on the Ist floor cabin it shall be first laid inside the ground floor of the cabin by cutting the masonry structure of the wall of the cabin and then it will be taken through a HDPE pipe fixed vertically on the inside of the cabin wall by suitable clamps to be embodied on the wall as directed by engineer-in-charge.

3.9 LAYING OF CABLE IN SPECIAL CASES

3.9.1 NEAR POWER CABLE

When the contractor comes across any other cable already laid, he shall first report the fact to the engineer & cable should be identified by the Engineer as a power cable (Lt or HT) the trench shall be dug as far away from the route of the power cable as practicable.

77 of 94

3.9.2 CROSSING OF TLECOMMUNICATION CABLE WITH ANOTHER CABLE.

Crossing of the telecommunication cable with another cable shall be avoided wherever possible. Where however, this is not possible, the telecommunication cable shall be laid in cement or asbestos cement pipes. The length of pipe to be provided on either side of the crossing shall be at least one meter.

3.9.3 LAYING OF OTHER THAN TELECOM CABLE IN THE SAME TRENCH

No other cable shall be laid in the trench for the telecommunication cable. Where, however, exceptional circumstance exit, the telecommunication cable may be laid along with another cable in the same trench provided a specific permission of each such case is obtained in writing from Engineer. When telecommunication cable and L.T power cable/ Signalling cable have to be laid in the same trench they shall be shall be separated by placing a layer of brick between them vertically (approx. 16 bricks/ meter) or laid in HDPE pipe.

3.9.4 LAYING OF CABLE THROUGH PIPES.

i) The cable shall be laid through G.I./ HDPE pipes at the locations marked on the tapping and route plan and as advised by the Engineer or his representative.

ii) Laying the cable through pipes galvanized steel wires of a cross section not less than 10 SWG shall be used as a lead wire. Two such lengths of wires shall be laid through the pipes, so that after the cable is threaded through the pipe, one lead wire is permanently left in the pipe with a suitable overlay at two ends, to eagle the cable to be pulled out at a later stage if required to do so.

iii) On arch bridges and culverts bridges the cables will be threaded through GI/ HDPE pipes etc. while threading the cable through these pipes the contractor shall do the trenching to the required depth wherever necessary for which no extra charge will be paid.

3.9.5 LAYING NEAR ONLY SURFACE.

If during the excavation of trenches for laying cables the contractor or his representative notice the presence or oil or oily substance or any other chemical which is likely to cause the deterioration of the cable protective material he shall bring the matter to the notice of the engineer or his representative and on the latter's decision he shall choose an alternative cable route or he shall protect the cable in such places in such a manner as advised in writing by the engineer or his representative. No additional charges are payable.

78 of 94

3.9.6 SPECIAL SOIL CONDITION

Cable should not be run through abnormally high acidic or alkaline soil or through sewages. If this is unavoidable special measures should be taken against corrosion as advised by the engineer in charge.

3.9.7 PROTECTION AGAINST DAMAGE DUE TO SHARP EDGES

When cable is laid in trucking care should be taken to see that no ballast or stones have been dropped inside the trunking, should be cleared of all ballast and stones before the cover is secured. When the ends of covers are joined together with cement plaster a piece of paper or wood should be placed under the joint to prevent the cement plaster from falling on the cables.

3.10 HANDLING OF CABLE DRUMS & LAYING OFF CABLES

3.10.1 The drums shall be unloaded by the side of the Railway Track from either a crane or any other suitable means very carefully so as not to cause any damage to the cable. The drums at site shall be protected until they are laid.

3.10.2 On each drum there are two ends, A&B. The 'B' end of one cable length shall meet 'A' end of the next cable at a joint. The 'A' end shall be normally on the top unless indicated otherwise on a drum.

3.10.3 The drums shall always be kept upright i.e. axle in parallels position to the base.

The drums shall not be set by jerks but shall be handled slowly and with care. The walls of the drums should not be damaged while moving the drums if required for unrolling.

3.10.4 The drums shall normally be unrolled at the same place and the cable carried by workmen near the trench. The drums shall not be dragged in any case, but where drums of cable have to be moved would always be rolled in the direction of the arrow, otherwise the coils tend to unwind and the cable may get battered. In case no direction arrow is marked on the drum remove several battens and determine the direction in which the cable is coiled. The arrow should then be painted on the drum pointing in the opposite direction in which the upper cable end is coiled so that future handling of the cable drum is facilitated and then replace the battens carefully.

3.10.5 The drum should be properly mounted on jacks (or on a cable wheel) making sure that the spindle is strong enough to carry the weight without bending and

79 of 94

that it is laying horizontally in the bearings so as to prevent the drum creeping to one side or the other while it is rotating. Before attempting to pull off the cable, remove the end protection box attached to the flange of the drum and cut the security ropes so as to leave the cable and free to move.

3.10.6 If a portion of the cable only is taken out from the cable drum, the battens should be immediately replaced to prevent damages to the balance of the cable. This is important.

3.10.7 With armored cables having Hessian serving it is possible under extreme conditions for the bitumen to soften and cause adjacent turns of the cable on the drum to stick to each other. In such cases, particular care must be taken to pull the cable of these drums very slowly and to free the cables carefully from the adjacent turns on the drums. Snatching of the cable to cause it to break away may result in kinks and damage, small size cable require care in this respect.

3.10.8 The use of steel bars between the bolt heads to 'jump' or turn the drum around is dangerous to staff and likely to damage the drums. A better method is to use two steel plates with grease between them by standing the drum on these greased plates; it can be easily turned round to the desired position.

3.10.9 All care should be taken in handling cable drums with a view to ensure safety not of the cables but also of the working party handling them. The man should not be allowed to brake the cable drum by standing in front but only from side.

3.11 REWINDING AND REDRUMING OF CABLES.

i) If for any reason it is found necessary to rewind a cable on a drum, cable drum, cable drum with a proper barrel diameter not less than of the original drum should be chosen.

ii) The drums should be mounted on cable jacks during rewinding operations using proper size of spindles passed through the flange holes, which will not buckle under the lead.

The cable should not be bent opposite to the set it is having already.

iii) In the redruming operation the full and empty drums should be so turned that the cable passes from the bottom of the original set as little as possible.

iv) Replace all the laggings on the cable drum.

3.12 CABLE LAYING

80 of 94

3.12.1 It is advisable to employ the same people at the same place or job while cable is being laid.

3.12.2 Before commencement of the laying inspection of the trench and inspection of protection works should be carried out so as to ensure their conformity with the specification. The trench bottom should be clean, smooth and free of small stone. When the soil contains stone or pieces of rock and therefore cannot be raddled, sieved earth about 10 cm thick should be used both for the bedding on which the cable is laid and for covering the cables.

3.12.3 The cable drum should be brought as close to the cable trench as possible. It should be lifted with the aid of cable jacks firmly mounted on a support of stone or wood. The spindle should be minimum of 55mm diameter and lower edge of drum should be 5 to 10 cm above the ground.

3.12.4 Where necessary the cable drum may be placed at such a point so that 2/3 of the cable is laid directly and the balance in other direction. Care should be taken in such a case to see that there is no kinks or loops in the cable.

3.12.5 The wooden battens on the drums should be carefully removed shortly prior to laying and before the drum is mounted on the jack. The nails on the lagging should be carefully removed.

3.12.6 While rolling a cable drum for laying the drum shall be supported on an axle running through its center the height of the axle being such that the end frames are free to rotate and do not touch the ground at any point. The cable shall be carefully uncoiled by gently pulling the cable assisted as necessary by carefully turning the drums quick pulling of the cable or turning the drums shall be avoided at all cost. Each cable drum shall be broken while laying is in progress to prevent sharp bending or buckling, particularly when the cable coils are sticking together.

3.12.7 The following personnel shall be employed near the drum.

1 Man : for handling the brakes.

1 Man : for permanent observation of the uncoiling of cable.

2 Man : for uncoiling close to the drums.

3.12.8 The method of mounting the brakes is shown in Drg. No.RITES/LKO/PO/TEL/21.

3.12.9 When drums are turned for change of direction, wooden blocks shall be carefully put under the drum bolts, which stand out from the drum discs.

3.12.10 It is customary for the mate to stand in a commanding position where he can view the entire route and shout evenly timed calls to his men to pull. If

81 of 94

there is proper synchronization between the mate's calls and the pulling by the men, the cable will leave the drum without difficulty. It is important that the cable should be pulled with steady and even pulls and not be unnecessarily jerked or strained. On no account should a cable be allowed to twist or kink, as this is likely to spring the Armour and fracture the paper insulation and outer serving of the cable. When pulling cable around bends, one or two men should be stationed to give the cable the correct bend when it passes.

3.12.11 When the cable drums are exposed to great heat before laying, them danger exists that the individual coils and layers stick together in spit of the half overlay.

Special attention should be paid to see that no buckling of the cable occurs while pulling the cable. A man should stand near the drum and loosen the cable carefully by hand and shout a warning whenever the cable cannot be loosened. Separation must be affected as close to the drum as possible as otherwise kinks may result. The rate of pulling should also be slow to prevent possible damage to cable that is being carried when the paying out stops. The drum should be kept in shade where possible.

3.12.12 While laying the cable employ adequate number of men such that the cable can be conveniently carried by them in both hands without stretched arms. The distance between any two persons carrying the cable shall be from 2 to 10 metres depending upon weight of cable such that the maximum sag of the cable between any two persons is not more than 0.5 meters.

3.12.13 The cable shall be gently drawn by pulling the cable, which may be assisted as required by smoothly, and slowly turning the winch. The cable shall not be twisted on any account.

3.12.14 Before laying is commenced the cable shall be uncoiled first in a straight line supported by men and then carried to the trenched and laid gently & carefully. Cable should be laid as per engineer-in-charge directives.

3.12.15 While the laying work is in progress one man must continuously observe the cable and feel along its length in order to determine whether any indentations holes or other damaged parts are apparent. Such damaged parts have to be protected immediately by the cable jointer provided with the laying party.

3.12.16 When two or three turn of cable are left on the drum the pulling should be stopped and the inner end of the cable removed from the slot in the drum. Pulling should then be continued. If this is not done the cable end is likely to be stretched and damaged.
