This document provides a summary of a presentation on practical training taken at the NWR Coach Care Complex in Jaipur from May 15 to June 30. The presentation covered the history of Indian railways, introduced different types of railway coaches including ICF and LHB coaches, discussed their advantages and disadvantages, and described couplings, toilets, braking systems, and train maintenance procedures. Key points included that Indian railways was founded in 1845, LHB coaches have higher speeds and capacities than ICF coaches, and different maintenance schedules are followed including washing, sick, IOH, and POH routines.

3. HISTORY OF INDIAN RAILWAY
● Indian Railway founded 8 may 1845 (172 year ago)
● In 1849 GIPR(Great Indian Peninsula Railway)
was established by East India Company.
● First train in Indian Railway between Mumbai to
Thana on 16th April 1853.
● Now 17 Railways Zones one is NWR Jaipur and
Jaipur junction established in 1875 and in 2002 it
made a NWR Zone
● One of India’s most famous and luxurious train
The Palace On Wheels stop at Jaipur.

4. RAILWAY INTRODUCTION
● Minister of Railways – Piyush Goyal.
● Indian Railway runs around 11000 trains every day of
which 7000 are passenger trains.
● Presently 9 pairs of Rajdhani and 13 pairs of shatabdi
Express trains run on rail tracks of India.
● Indian railway is 3th largest railway network in the
world having route length of 66,687km(41,437).
● 6,909 Total stations in Indian railways.

5. TYPES OF RAILWAYS
COACHES
• Mainly used in Indian railways
coaches
• ICF Coach
• LHB coach

6. ● Integral Coach Factory ( ICF COACH)
● The Integral Coach Factory is located in Chennai.
● Max. Speed of coach – 110km/h
● Noise level 100 decibels
● Frame is made of mild steel.
● srew coupling is used to COUPLE
two coaches.
ICF COACH

7. ● Linke Hofmann Busch (LHB) coaches
● that have been developed by Linke-Hofmann-Busch
of Germany
● Noise level of 60 decibels
● Max. speed of coach-160 km/h
● Made of aluminum so light in
Weight.
● Center buffer coupling (CBC) is
two couple two coachs

8. ADVANTAGES OF LHB COACHS
 These are formed at Kapurthala, Punjab and in Raebareli.
 These are 1.7m longer than ICF coach thus inhance seating
capacity.
 These coaches used FIAT bogies instead of ICF bogies.
 These are employed with disc brakes.
 Controlled discharge toilet and bio toilet are used in these
coaches.
 Overall maintenance and manufacturing cost of these
coaches is less than ICF coaches.

9.  ICF coaches are over climb over another
and crash badly at the time of accidents
so that no. of people were killed.
 But LHB coaches don't climb over
another, they were derail at the time if
accidents, they have anti telescopic
design so there is minimum chances of
crashing.

11. Disadvantages of LHB coaches
● LHB coaches is not self
generating like ICF, they are
working on EOG system ( end
on generation).
● It uses two generator or power
cars in full rake one at each
end.
● Each supplies 3 phase 750V
AC power.
● This voltage is stepped down
to 3 phase 400V and supply to
coaches.
● It produces very loud noise.

12. In ICF coaches ● ICF coaches are self generating
(SG).
● They have collection of batteries
under the coaches.
● One batteries is of 110V DC
supply and cell is of 2 V.
● Alternator is mounted on axle of
bogie provide current to these
batteries after discharging .
● Batteries have a life of 3 years.
● VRLA batteries are used .
● These are different from lead acid
batteries .

13. ICF bogie
FIAT
bogie

14. Bio toilet
● It has seven chamber containing
high grade bacteria.
● Waste goes from one to last
chamber is decompose by
bacterias.
● After this waste convert into
water and methane and
discharged when train is at high
speed.
● These bacterias are self
generating.

15. Coupling
screw coupling in
ICFcoaches
center buffer coupling in LHB
coaches

16. ● Direct release air brake system
● Graduated release air brake system
● Types of Graduated release air brake
system
● Single pipe and
● Twin pipe
Classification of air brake

17. ● DIRECT RELEASE SYSTEM
● Air released immediately in single pass, as soon
as releasing of brakes is initiated.
E.g.: freight trains
● GRADUATE RELEASE SYSTEM
● Brake cylinder pressure can be reduced gradually in
steps in proportion to the increase in brake pipe
pressure.
E.g.: passenger trains

18. ● Washing line :-
■ after every 2500 km
● Sick line :-
● Schedule “A” maintenance- 1
month
● Schedule “B” maintenance- 3
months
● IOH- 9 months or 2,00,000 km
● POH- 18 months or 4,00,000 km
● Platform Train Duty:-
■ on starting & ending stations
Train maintenance
