This document provides information about air brake systems used on Indian railways. It discusses the history of air brakes, which were invented in 1872. It then explains the working principles of single pipe and twin pipe air brake systems used on trains. The key components of these systems are described, including compressors, reservoirs, brake pipes, valves, cylinders and more. Advantages of air brakes are their reliability and effectiveness even with leaks. Limitations include higher maintenance needs and initial costs compared to other brake types. In conclusion, air brakes are well-suited for heavy-duty applications like trains and mining due to their performance.

3.  This fail-safe air brake system is based upon a design
patented by George Westinghouse on March 5, 1872.
 An Air Brake is a conveyance braking system actuated by
compressed air.
 Before 1872 a piston like plate was used on the train wheel
for continue the braking system.

4. After 1872 by using air braking system
baker's are use to brake the wheel.

 In Indian railway there are different type of
coaches which are manufactured by
different units
 ICF
 RCF
(Integrated Coach Factory), Chennai
(Rail Coach Factory), Kapurtala
 BEML (Bharat Earth Movers Limited),
Bengaluru

6. What is brake ?????
6
A brake is a device by means of which
artificial resistance is applied to a moving
machine member, in order to slow or stop
the motion of a machine.
What is Air Brake system ?
Brakes applied with the help of air pressure
are called Air Brakes and the system
actuated to apply this phenomenon is
called as Air Brake System.

7. Air Brake Concept
7
Basically air brake’s are uses on heavy
vehicle's.
There are two type’s of air braking
system.
Single pipe braking system.
Twin pipe braking system.

 Compressor:
The pump which draws air from atmosphere and
compresses it on the train.
 Main Reservoir:
Storage tank for compressed air for braking and
other pneumatic system.
 Feed Valve:
To ensure that the brake pipe pleasure remains at the
required level.

11.  Brake pipe:
The pipe running the length of the train.Which transmits
the variation in pressure required to control the brake.
 Angle cocks:
At the end of the each vehicle angle cocks are provided
to allow the ends of the brake pipe hoses.
 Brake cylinder:
Each vehicle are at least one brake cylinder.
Sometimes two or more are provided.
11

12.  Auxiliary reservoir:
There is always a source of air available to operate the brake
auxiliary valve is connected on one side of the piston of triple valve.
 Brake bloke:
This is frictional material which is pressed against the
surface of the wheel.
 Triple valve:
The orientation of the brake on each vehicle is
controlled by the tripled valve.

13. 2.Twin pipe braking System
Twin pipe is the advanced process on which
it is possible to use of the air in the auxiliary
reservoir more quickly then brake pipe can
recharge it.
 Basically there are two pipes are use
on the each vehicle.

15. Advantages
15
 Air is available everywhere in
atmosphere so the brake can never run
out of its operating.
 Air does not corrode the metals so the life
of pneumatic brake is more.
 Air brakes are effective even with
considerable leakage, so an air brake
system can be designed with sufficient
fail-safe capacity to stop the vehicle safely
even when leaking.

17. Conclusion
 Due to it’s maximum effectiveness in terms of
performance, it is mostly preferred for high end works
like supercars, mining work etc.
