• Three phase A.C. induction motor
• Fail safe braking system with regenerative braking.

15. Car Body:
RS-2 trains have three different car bodies, one for each type of car in the train set.
• DT car body
• M car body
• T car body
The function of car body shell is to carry and protect the passengers, staff and various
subsystems of the train. The car body shell distributes the accelerating and braking forces
generated by the bogie.
• FUNCTIONS OF CAR BODY:
• To carry passengers and the payload.
• To protect the passengers and the payload against external forces.
• To protect the passengers and the payload against moisture, heat, cold, vibration and noise
etc.
• To support other subsystems.
• To transfer tensile and compressive loads between cars.

gangway halves, is the flexible part
of the train, allowing relative
movements between the cars and
offering passengers a secure and
comfortable passageway.
• All intermediate car ends are
connected via intercommunication
gangways to allow free and safe
passenger movement between cars,
including when the train is in
motion. Passengers can stand
within the gangway with a high
degree of safety and comfort.
Furthermore, the gangway design
ensures

23. Coupler
• Automatic coupler
• The main task of the automatic
coupler is to allow mechanical
and pneumatic coupling. These
are fitted at the outer ends of a
train set and are links between
train units.
• Semi-permanent couplers
• These couplers are used
between the cars within a 2-car
unit, which are joined together
with a separate muff fixed with
screws and nuts. The couplers
mechanically connect one car to
another and form a rigid and
slack free connection.
• Intermediate Automatic
coupler
• The main task of the coupler is
to allow mechanical coupling
between the cars in the train
set and to transmit
compressive and tractive
loads.

24. Brake and pneumatic system:
• The brake system is a combination of mechanical and electronic devices operated by
compressed air, arranged in a system and controlled manually, pneumatically or
electronically by means of which the motion of cars is retarded or stopped.
• The brake system includes-
• Friction brake
• Electro Dynamic (ED) brake
• Parking brake
• Holding brake
• Wheel slide protection (WSP)

25. Air Supply System
The air supply system supplies compressed air to consumers, such as the brake
system, secondary suspension and pantographs.
The main air supply unit is the subsystem of train and is fitted in the underframe of
each M-car which supplies compressed air to the complete train via the Main
Reservoir Pipe (MRP).
Air supply unit basically consists of:
• Compressor
• Air treatment
• Filter units

27. Heating, Ventilation and Air-Conditioning (HVAC):
• The Heating, Ventilation and Air-Conditioning (HVAC) system is used for heating, cooling
and ventilation of the saloon area as well as cab area.
• The primary function of the HVAC unit is to achieve and maintain acceptable indoor
climate and air quality for the passengers.
• Secondary functions are:
• To protect the passengers from smoke in case of smoke outside the train, and
• To secure the CO2 levels inside the train if auxiliary power fails.

28. Major components:

29. Doors
A door in a train is a panel or barrier, usually hinged or sliding, that is used to cover an
opening in a train. Exterior doors are doorways that allow entrance or exit from a train.
There are three types of exterior doors available in RS2:
• Cab or driver’s door
• Passenger door
• Detrainment door
• Cab doors
• The function of the cab or driver’s door is to provide access to the cab for the driver.
