3. Introduction to Indian Railways
 Railways 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.

5. Introduction to Locomotive
Workshop Lucknow
 This 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

6. Tracks And Guages
 Indian railways uses three gauges
 the 1,676 mm (5 ft 6 in) broad gauge
 which is wider than the 1,435 mm (4 ft 8 1⁄2 in)
standard gauge;
 the 1,000 mm (3 ft 3 3⁄8 in) metre gauge; and two
narrow gauges
 The total length of track used by Indian Railways was
about 114,000 km .

8. Section of Locomotive
 Locomotive Engine is divided into five Section
* Nose : Small section where Batteries are placed
* Driver’s 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

10. 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 gauge
 The 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

11. Nomenclature of Locomotive
The 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

12. TRANSMISSION TYPES OF
DIESEL LOCOMOTIVES:
 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

13. Indian Locomotive Class WDM-2

14. Indian Locomotive Class WDM-2
 The 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.

16. Power Pack Assembly of Diesel
Locomotive

17. Main Parts & Accessories of
Power Pack
 The 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.

18. pumps
 LUBE 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.

20. TURBOSUPER CHARGER
Turbochargers 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.
