INTRODUCTION
 In 1849 GIPR (great Indian peninsula railways) was established by East India Company
 Railways were first introduced to India in the year 1853 from Mumbai to Thane
 It is one of the largest networks in the world.
 IR runs more than 13,000 passenger trains daily, on both long-distance and suburban routes,
from 7,349 stations across India
 In the year ending March 2018, IR carried 8.26 billion passengers and transport 1.16 billion tonnes of
freight
Nomenclature of LOCOMOTIVE
The name of the locomotive are provide according to the gage, type of fuel and load. Generally 4 or 5 letter are
used.
First letter are denote the size of the gage
Letter Gage type Size (mm)
W Wide gage 1676
Y Miter gage 1000
Z Nero gage 762
N Nero gage 610
Second letter is used for the type of fuel
D Diesel
A AC current
C DC current
CA Dual traction (AC/DC)
Third letter is used for the type of the load
P Passenger
G Goods
M Multipurpose
S Shunting
U Multiple unit
R Rail car
Fourth letter is used for the horsepower
1 1000 HP 1A 1100 HP
2 2000 HP 2A 2100 HP
3 3000 HP 3A 3100 HP
General Introduction of Diesel Loco
Diesel locomotive is a self-propelled vehicle running on rail tracks, which pulls the train by transforming the thermal energy to
mechanical energy
In India, Diesel loco is currently working in energy transmission of 500HP to 5500HP.
Parts of the Diesel locomovite-
• Prime Mover(Diesel Engine) – It is used to generate mechanical energy in diesel loco.
• Storage Tank- For the accumulation of fuel
• Transmission Mechanism - for transferring mechanical energy form the engine to the wheel
• Control System- for regulating the energy generated
• Breaking System
• Lighting System
• Alert Mechanism
• Auxillary Device –to encriese unit efficiency
Prime Mover(Diesel Engine)- Diesel Engine is equipped with 16 cylinder
It has the followings parts
i. Engine Block
ii. Crank Case or Crank Shaft
iii. Cylinder Linear
iv. Connecting Rod
v. Cylinder Head
vi. Cam Shaft
vii. Valve
viii. Valve Assembly
ix. Lifter Assembly
Storage Tank
The feature of the fuel oil system in the loco is that in the appropriate amount, at the right time,
with high pressure, the fuel is sprayed in the cylinders for the ignition.
In the loco, the fuel tank is made by welding plates of steel between the two bogies.
Type of LOCO Capacity in Liters
WDM2 5000
WDG3A 6000
WDP3A 6000
Capacity of Fuel tank
To know the amount of fuel in the tank, glow rod gauges are formed.
Transmission system
Mechanical Transmission-
In this system the torque generated by engine is transported as mechanical energy to the wheels through gears,
chain-pull, belt, ratchet etc. This mechanism was used in steam loco. It is currently completely obsolete.
Electrical Transmission-
In this system the mechanical energy generated by the engine is
transmitting by the alternator
Is sent to traction motors, through the controller tips and regulatory
devices. Nowadays, this type of mechanism is used in
All types of loco. In this, the movement of loco is controlling the
current given to the traction motors and direction can be changed.
Brake System
There are 2 types of braking system used in the railways
1. Air Brake
2. Dynamic Brake
Air Brake
When loco engine driver made upto pressure of BP
5kg/cm^2, the air finally enter into distributer valve through
brake pipe and R-Charger.
When the driver decrease the pressure of brake pipe then
the pressure in brake cylinder increase, this is happened
because auxiliary reservoir gets connected to brake cylinder
via distributer valve where air pressure push the piston of
brake cylinder outside.

Wagon
Wagon is a rolling stock which is used by Indian railways for transporting goods from one place to another place.
Wagons are classified into following categories
Type of Wagon Life (Years)
Open Wagon 30
Covered Wagon 35
Guard Wagon 25
Tank Wagon 40-45
Flat Wagon 30
Different types of wagon names
BOXC – B means Bogie type, O- open Wagon, X-High Sided, C-Axle Load of 20.32T with Centre Buffer Coupler
BCN - Bogie type Covered Wagon Fitted with Air Brake System
BVG – Brake Van Guard
BTPN – Bogie type Tank Wagon for Petroleum products fitted with Air Brake system
Bogie Shop
A bogie is a chassis or framework that carries a wheelset, attached to a
vehicle-a modular subassembly of wheels and axles.
Type of bogie are used in wagon and freight vehicles are-
1. Diamond Bogie
2. UIC Bogie
3. CASNUB Bogie
Diamond and UIC bogies are now absolute because they have fabricated frame which was difficult to machine
Wheel Shop
Maintenance work of wheel, axle and bearing is also important. As it is known the wheel wears,
through its life. When at work, the profile and the diameter of wheel continuously change.
Diameter of different wheel machined in wheel shop-
Type New disk size
(mm)
Shop leaving size

BOXN Wagon 1000 919 906
BLC Wagon 840 793 780
DEMU 952 885 877
Initial diameter of axles – 252 mm
Last permissible diameter – 246 mm
