<ol><li> 1. DIESEL LOCOMOTIVE WORKS DIESEL LOCOMOTIVE WORKS PRESENTATION Shubham Vishwakarma Mechanical 3rd year AIMT Greater Noida </li><li> 2. INTRODUCTION - Diesel electric locomotives were introduced on Indian railway in 1950's. - Diesel Locomotive Works ( DLW ) was established in 1961 in collaboration with M/s ALCO, USA in the ancient city of Varanasi. It is spread in 300 acres area at Varanasi. - it is a production unit owned by Indian railway, for which it manufacturers diesel -electric locomotive and its spare parts. - DLW is an ISO 9001:2008, ISO 14001:2004 and OHSAS 18001: 2007 Certified organization. </li><li> 3. First Locomotive was flagged off by Late Shri Lal Bahadur Shashtri on 3rd February 1964. </li><li> 4. - In order to upgrade the technology, Indian railways entered into an in 1995, with M/s General Motors, USA for transfer of technology for the manufacture of 4000 HP, fuel efficient WDG4/WDP4 locomotives at DLW. - At present the latest locomotive produced by DLW; I.e WDG5 has capacity upto 5000 HP and trying to make it 5500 HP - DLW is supplying locos to PSU's &amp; industries like NTPC, COAL, INDOGULF etc. - DLW has also supplied locomotives to other countries such as Sri Lanka, Bangladesh, Malaysia, Vietnam etc. </li><li> 5. SOME FACTS ABOUT DIESEL ELECTRIC LOCOMOTIVES - DLW's annual Production - 25 - Cost of one loco - 12 to 14 crore (EMD) - 8 crore (ALCO) - Weight of one loco - 121 ton - Fuel consumption; At full load - 540 lt/hr. Idle load - 40 lt/hr. - Max. Speed - 160 Km/hr. - Dia. of wheel - 1092 mm - Wheel to wheel distance - 1596.5 mm - Length of under frame - 19962 mm </li><li> 6. DIESEL ELECTRIC LOCOMOTIVE In a diesel - electric locomotive, the diesel engine drives an electrical generator or alternater whose output provides power to the traction motors. There is no Mechanical connection between the engine and the wheels. </li><li> 7. CLASSIFICATION OF LOCOMOTIVES - Locos, except the older steam ones, have classification codes that identify them. This codes is of the form WDG5A "| Gauge || power || load || series || subtype |" - THE FIRST LETTER (Gauge) W - Indian broad gauge Y - Meter gauge Z - Narrow gauge (2.5 ft) N - Narrow gauge (2 ft) - THE SECOND LETTER (Motive power) D - Diesel C - DC electric ( can run under DC traction only) </li><li> 8. A - AC electric ( can run under AC traction only) CA - Both DC and AC ( can run under both AC and DC traction) B - Battey electric locomotive ( rare) - THE THIRD LETTER (Load type) G - Goods P - passenger M - mixed traffic; both goods and passenger S - used for shunting U - electric multiple units ( E.M.U ) R - Railcars </li><li> 9. - THE FOURTH LETTER ( Series) The series digit identifies the horsepower range of the locomotive. Example. For the series Letter '3' means that the locomotive has power over 3000 HP but less than 4000 HP. - THE FIFTH LETTER (Subtype) An optional letter or number that indicates some smaller variations in the basic model. For Ex. 'A' for 100 HP 'B' for 300 HP </li><li> 10. PRODUCTS WDG-5 - High adhesion Diesel-electric 5500 HP main line heavy goods service locomotive, with GM ( AC-AC traction) WDG-4D - High adhesion Diesel-electric 4500 HP main line heavy goods service locomotive, with GM ( AC-AC traction) </li><li> 11. WDP-4D - High adhesion Diesel-electric 4500 HP main line heavy pessenger service locomotive, with GM ( AC - AC traction) WDG3A - 3100 HP main line heavy goods service locomotive, with uprated 16 cylinder ALCO engine ( AC -DC traction ) </li><li> 12. WDS6 - 1350 HP Diesel- electric shunting/short haul locomotive with 6 cylinder. 2.4 MW DG Sets - 2.4 MW DG Set using 16 cylinder, 3600 HP ALCO Diesel Engine. </li><li> 13. PRODUCTION SHOPS AT DLW 1.

Conventional Machine 2. NC Machine 3. CNC Machine - CONVENTIONAL MACHINE : It is a simple machine which is now an Old technique. - NUMERICAL CONTROL MACHINE : Numerical control is defined as a system in which the actions of the machines are controlled by the Insertion of the numerical data. In other words number Controls the action. </li><li> 17. COMPUTERISED NUMERICALLY CONTROLLED MACHINE - In CNC the control system further energized With a mini computer or a post processor. - The control unit stores the programmed Information of the work piece, the travel Limits, collision zones and the diagnostic information etc. it also gives a feedback to The operator about the current position and distance to be travelled etc. - CNC Machine have ability to edit or alter the existing program in no time. </li><li> 18.
