Introduction to Indian RailwaysRailways serve the people of India since 1853. Indian Railways are the biggest organization in our country, which is engaged in transportation.

Indian Railways has more than 64,215 kilometres (39,901 miles) of track and 7,083 stations. It has the world's fourth largest Railway network after those of the United States, Russia and China.

Introduction to Locomotive Workshop Lucknow Front View of Workshop

Introduction to Locomotive Workshop LucknowThis Locomotive Workshop was established by the princely state of Oudh & Rohilkhand Railway (O&RR) at Lucknow in 1867.After about sixty years, that is in the year 1925 the O&RR was taken over by the Eastern Indian Railway (EIR) along with all assets and liabilities Subsequently in 1952 the EIR merged with Northern Railway. Currently, the periodical overhauling (POH) and maintenance of diesel locomotives like WDM-2, WDM-3A and WDM-3D is done in the workshop

Tracks And GuagesIndian railways uses three gaugesthe 1,676mm(5ft6in) broad gauge which is wider than the 1,435mm(4ft812in) standard gauge; the 1,000mm(3ft338in) metre gauge; and two narrow gaugesThe total length of track used by Indian Railways was about 114,000 km .

Tracks And Guages

Section of LocomotiveLocomotive Engine is divided into five Section* Nose : Small section where Batteries are placed* Drivers Cabin : Next to Nose all controls are in this section* Power Pack Assembly or Engine : Main section of locomotive * Compressor section : Compressor are attached with crank shaft via coupling *Radiator : Last section from where thermal energy in of locomotive discharge outside

Classification of Locomotive

In India, locomotives are classified according to their track gauge, motive power, the work they are suited for and their power or model number. It comprises 4 or 5 letters. The first letter denotes the track gaugeThe second letter denotes their motive power (Diesel or Electric) The third letter denotes the kind of traffic for which they are suited (goods, passenger, mixed ).The fourth letter will denote their horsepower range.The fifth letter generally denotes a technical variant or subclass or subtype. For example WDM 2A

Nomenclature of LocomotiveThe code is of the form [gauge][power][load][series][suffix] GUAGE- W(BROAD) Y (METRE) Z (NARROW,2.6) N (NARROW,2) POWER D = Diesel C = DC traction A = AC traction CA = Dual-power AC/DC B = Battery electric (rare)

LOAD- M = Multipurpose P = Passenger G = Goods L = Light Duty (Light Passenger) R = Railcar

SERIES- 1 over 1000 hp less than 2000hp 2-over 2000 less than 3000 3--over 3000hp less than 4000hp 4-over 4000 less than 5000

SUFFIX-A-100HP B-200HP C-300HP D-400HP


Unlike steam engines, internal combustion engines require a transmission to power the wheels. The engine must be allowed to continue to run when the locomotive is stopped.The Transmission are of two types DIESEL-MECHANICAL DIESEL-ELECTRICAL

Indian Locomotive Class WDM-2

Indian Locomotive Class WDM-2The class WDM-2 is Indian Railways' workhorse diesel locomotive. The first units were imported fully built from the American Locomotive Company (Alco) in 1962. Since 1964, it has been manufactured in India by the Diesel Locomotive Works (DLW), Varanasi. The model name stands for broad gauge (W), diesel (D), mixed traffic (M) engine.

Dimensions of WDM-2

Power Pack Assembly of Diesel Locomotive

Main Parts & Accessories of Power PackThe POWER PACK (engine) of the diesel locomotive consists of various parts and accessories fitted and attached to it.

The LUBE OIL SUMP, ENGINE BLOCK and HEADER are combined together to form the power pack during the assembling process of the power pack.

pumpsLUBE OIL PUMP : This pump helps in the circulation of the lube oil to various parts and accessories of the power pack for the purpose of lubrication. It draws the lube oil from lube oil header and circulates it with required optimum pressure to various parts

WATER PUMP: It is a type of centrifugal pump whose main function is to circulate water through parts and accessories of the power pack necessary to cool and reduce the temperature by absorbing heat.

LUBE OIL SCREEN: It acts as a filter which helps in filtering of the lube oil coming to the sump after circulation to various parts. It separates impurities and metal parts from the lube oil.


TURBOSUPER CHARGERTurbochargers were originally known as turbosuperchargers when all forced induction devices were classified as superchargers. Nowadays the term "supercharger" is usually applied only to mechanically driven forced induction devices. The key difference between a turbocharger and a conventional supercharger is that a supercharger is mechanically driven by the engine, often through a belt connected to the crankshaft, whereas a turbocharger is powered by a turbine driven by the engine's exhaust gas.
