1. A
PRESENTATION ON
RAILWAY WORKSHOP
JAGADHRI,

3. In 15th century stone slabs or wooden baulks were laid flush wit
h the road surface for carriage of heavy goods loaded on carts and drawn
by animal. These were called ‘Tram ways’. These tram ways were extensi
vely used in 16th century in means in central Europe for carriage of coal
and others minerals.
The timber baulks were replaced by iron plates to reduce wear a
nd these were called ‘plate ways’. William Jessop in of U.K. in 1789 repla
ced iron plates with cast iron beams having stone supports at end of batt
er working .
HISTORY OF RAILWAY

4. Carriage and Wagon Workshop,Jagadhri
Jagadhri Workshop is a Periodic Over
Hauling(POH) unit under ministry of
Railway.
Jagadhri workshop was founded in 1865
and it is one of the oldest C & W worksho
p in india.
The foundation stone of this workshop w
as laid on 8-12-1952 with bare minimum
facilities for undertaking the POH work for
3 unit of coaching stock and 9 unit of
goods stock per day

5. Body:
The body of the vehicle usually has a
continuous under frame for carrying
the weight of the body and the
commodities passengers. The body
comprising of the under frame,
sidewalls, and end walls and its
dimensions also the interior is
designed according to its use.
IMPORTANT SYSTEMS & COMPONENTS OF ROLLING STOCK

6. Coaches:
Vehicles designed for carrying
passengers are called coaches.
In addition, certain other
vehicles attached to
passenger trains are also
covered under the coaches.
COACHES:

7. Wagons:
Vehicles designed for carrying
various commodities are called
wagons. These may be open,
covered, flat, tank or other
types depending upon the
commodity to be transported
WAGON:

8. LOCOMOTIVE:
Traditionally, locomotives pulled
trains from the front.
However, push-pull operation has
become common, where the train
may have a locomotive (or
locomotives) at the front, at the
rear, or at each end
LOCOMOTIVE

9. Train:
Train is the group of
Vehicles and one or more
locomotives moving on
rail which needs line clear
to enter a block Section.
TRAIN:

10. Diesel Multiple
Unit:
This is similar to the EMU concept
except that these are powered by a
Diesel engine for operation on non-
electrified routes.
DIESEL MULTIPLE UNIT:

11. ELECTRIC MULTIPLE UNT:
ELECTRIC
MULTIPLE UNIT:
An EMU is usually formed of two
or more semi-permanently
coupled carriages, but electrically
powered single-unit railcars are
also generally classed as EMUs.

12. Bogies:
Super structure of any rolling stock
normally rests on bogies through the
medium of center pivot and side
bearers on the bogie bolster; the
bolster normally is supported on the
bogie frame. This arrangement
provides independence of movement
between the super structure
BOGGIES:

13. Wheels:
These may be solid or fitted with
types of special heat treated steel
shrink fitted on to the vehicle. With
conical surface and negotiate the
permanent way. These carry the
way load of vehicle. These can be
either cast or forged.

24. Ultrasonic Rays:
Are those rays whose frequency range is beyond hearing range i.e. greater than 20,000 cycles p
er sec.
Principle:
This test is based on the principle of piezoelectric effect i.e. if a material is subjected to mec
hanical vibrations their will be an e.m.f. generated at both surface or vice -versa.

25. 1.VACUUME BREAK SYSTEM
2.AIR BREAK SYSTEM
BREAKING SYSTEM:

26. As the term indicats vacuum is the moving is the working medium. The equipment consists of a vac
uum brake cylinder with piston and brake rigging provided under each vehicle. The amount of vacu
um maintained on one side of piston in the vacuum cylinder to operate the brake System IS about th
e 29 Inch of mercury which gives an effective working pressure of about 100 Lbs per Square inch on
the piston when brake are applied. The 'vacuums, Cylinder are designed to give the required amount
of brake power at the wheel the vacuum cylinders are continuously evacuated by exhausters provid
ed the locomotive.
VACUUM BREAK SYSTEM:

27. In it, compressed air is used for operating the brake system. The locomotive compressor charg
es the feed pipe and the brake pipes throughout the length of the train,. The feed pipe is conne
cted to the auxiliary reservoir and the brake pipe is connected to the brake cylinder through the
distributor valve. Brake application takes place by dropping the pressure in the brake pipe
