    Freight Wagon Designs for

    Indian Railways

    By G.C. Budhalakoti

    Ex. Dir. Wagon, RDSO

  • Historical Background

    Pre-independence (upto 1947)

    25 types of wagons designed by M/s Rendol Palmer in 75 years

    Axle load was 16.3 t

    Pay to tare ratio ranging from 1.09 to 2.64

    Post-independence (upto 1960)

    9 wagon designs developed by various designers from all over the world.

    Some of the important wagons are BOBS, BWS

    Axle load max. 22.9 t

  • Historical Background

    Post-independence (upto 1960)

    After formation of RDSO in 1957, responsibility of development of design taken by RDSO.

    First wagon designed by RDSO was BOX wagon in 1960

    Between 1960 & 1980 wagons with vacuum brake having UIC bogies were designed by RDSO.

    In 1980, BOXN wagon with air brake, Casnub bogie. CTRB & CBC was introduced.

    Since then BOXN and other wagons like BCN, BTPN, etc. having Casnub bogie became workhorse of IR freight transportation.

    Max. Axle load 20.32 t, Max. speed 100 Kmph

    Wagon

  • DOUBLE STACK CONTAINER

    OPERATION ON FLAT WAGONS

    Double stack container operation on flat wagons started in March06

    Limitation of axle load (20.32 t) & speed (max.75

    Kmph), resulting in restriction in container loading

    Bogie upgraded and Speed certificate for operation at 22 t axle load and speed of 100 Kmph issued in 2007.

  • Road Railer trains (Development with M/sKPC) Can be converted into trailer hauled by a truck and

    into normal wagon

    Carry white goods, automobiles, manufactured

    goods, perishables, fragile cargo,part load,etc.

    Faster turn around time

    Trials already done on IR

    Number of wagon per rake- 50

    Articulated Bogie, Slackless coupling

    Kirloskar Pneumatic Co. manufacturing one rake

    for braking distance trials

  • ROADRAILER CHASSIS IN ROAD MODE

  • ROADRAILER CHASSIS IN RAIL MODE

  • Double Stack Container Train entering in Botad Yard

  • Flyash Wagon (New traffic)

    Recently designed wagon for bulk

    transportation of flyash

    Special features are:-

    - Pay to tare ratio 2.14 for Flyash (3.02 for Cement )

    - No. of wagons/rake 58

    - Stainless steel (IRSM 44) underframe & body

    - Rake throughput of 2732 t

    - Can carry cement-rake throughput 3875 t

    - Axle load 22.9 t max. with Cement

  • Autocar WagonsDedicated wagon for transportation of autocars

    New Design Bi-Level Autocar Wagon type BCACB -

    Features

    - Can carry upto 294 autocars.

    - New bogie design with lower wheel dia (760-700 mm)

  • Ro-Ro Under Wire

    With the new bogie of 700 mm wheel dia

    of Autocar wagon, it is now possible to

    run Ro-Ro services under wire.

    RDSO has also undertaken the design of

    such Ro-Ro wagon.

  • Dedicated Freight Corridor

    Following two new corridors dedicated to

    freight traffic movement are being

    constructed:-

    Eastern Corridor-

    Main traffic- Coal & Ores

    Western Corridor-

    Main traffic- Containers

    Axle Load - 32.5 t (Final target)

    - 25 t (Starting)
