INTRODUCTION
 Planning for the metro Started in 1984,when the Delhi Development
Authority and the Urban Arts Commission Came up with a proposal
for developing a multi-modal transport system for the city . The
Government of India and the Government of Delhi jointly set up the
Delhi Metro Rail Corporation(DMRC) in 1995.Construction Started
in 1998,and
 The first Section, on the Red Line, opened in 2002,

 Followed by Yellow Line in 2004,
 The Blue Line in 2005,its branch line in 2009,
 The Green and Violet Lines in 2010 and
 The Delhi Airport Metro Express in 2011
The network comprising six lines with 140 metro stations.
Rolling stock
 The first wave of Rolling stock was manufactured by a consortium of companies
comprising ROTEM, Mitsubishi Corporation and Mitsubishi Electric Corporation. Initial sets
were built by ROTEM in South Korea, with later examples Completed in India by public
sector undertaking Bharat Earth Movers Limited(BEML).
 BEML is also responsible for the manufacturing coaches under technology transfer
agreement. The air-conditioned trains consist of four 3.2m wide ,stainless steel, lightweight
,although six and eight coaches is possible. The trains have automatic doors, secondary air
suspension and brakes controlled by microprocessor. Delhi Metro has fleet of 280 coaches,
which DMRC Runs as 70 trains everyday. Each train can accommodate about 1,500
people,240 seated. Maximum speed is 80km/h (50mph),with a 20-second dwell time at
stations.
 Train depots are located at Khyber Pass , Najafgarh, Shastri Park , Mundaka , Sarita
Vihar and Yamuna Bank.
 A Phase I board gauge train, supplied by Hyundai Rotem-BEML(RS-1).
 A Phase II board gauge train, supplied by Bombardier(RS-2).
 The Metro Rolling Stock of two different gauges. Phase I lines use 1,676mm (5.499ft) broad
gauge rolling stock, while three Phase II Lines use 1,435mm (4,708 ft)standard gauge rolling
stock.
Broad gauge
The broad Gauge rolling stock is manufactured by two major suppliers Hyundai Rotem ,
Mitsubishi Corporation and MELCO . The coaches were initially built in South Korea by ROTEM.
Standard gauge
The initial trains were made in Germany and Sweden, the remainder will be built at
Bombardier’s factory in Savli , near Vadodara. The coaches posses several improved features like
Closed Circuit Television(CCTV) Cameras , charging points in all coaches for cell phones and
laptops, improved air conditioning to provide a temperature of 25 degree Celsius even in
packed conditions and heaters for Winter.
RS-2 TRAIN OVERVIEW
TRAIN FORMATION:
One train set consists of 4/6/8 cars. Three types of cars (DT,T and M) are used to form a train set. At
each end is a “DT” car which is a trailer car with driver ’s cab and pantograph. The other type is an “M”
car, which is a motor car without pantograph and “T” car with pantograph.
-4 car
The 4-car trains consist of driving trailer car with pantograph (DT) and motor
car (M), in the following configuration DT-M + M-DT.
- 6 car
The 6 car train consists of driver trailer car with pantograph (DT), motor car
(M) and trailer car with pantograph (T), in the following configuration DT-
M + T-M + M-DT
- 8 car
The 6 car train consists of driver trailer car with pantograph (DT), motor car (M)
and trailer car with pantograph (T), in the following configuration DT-M + T-M +
T-M + M-DT.
SALIENT FEATURES:
• Broad gauge (1.676 metre )
• 25 KV Supply Voltage System
• Light weight stainless steel structure
• Three phase A.C. induction motor
• Fail safe braking system with regenerative braking.
TYPES OF COUPLINGS BETWEEN COACHES
1 Front Automatic Coupling (FAC)-is used at both ends of the metro train i.e., in front of
the DT car & is very useful in rescue operation
2 Semi- permanent Coupling (SPC)-between the DT and M cars. Since the DT and M cars
serve as one unit, they are not usually required to be separated. Hence, a semi- permanent
coupling is used between the two.
3 Intermediate Automatic Coupling (IAC)-This coupling is used between two M cars in order
to facilitate easy engagement of coaches especially when the number of coaches has to be
increased.
Train Integrated Management System
 Train Integrated Management System (TIMS) provides a centralized function
to monitor the train borne systems and devices. It also provides the operators
interface via a Video Display Unit mounted on the operator desk.
Additional information about other systems can be checked by driver by touching the soft keys at the bottom of
the screen display.
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)
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
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/emergency door
 Partition door
 The function of the cab or driver ’s door is to provide access to the cab for the driver. Only
DT car is equipped with two cab doors.
Passenger door
 The function of the passenger door is to prevent passengers from entering or
leaving the train.
 Each car has 8 passenger doors
 Each door consists of two door leaves
 Sliding externally on the car body wall
 Electrically operated
Detrainment/Emergency door
 The function of the detrainment door is to provide evacuation of passengers and
crew to track in case of emergency.
 When detrainment door opens it becomes an emergency ramp from cab floor
level down to track level.
 The detrainment door is bolted into the cab structure.
 The door is located in the front of the cab.
 Free opening width 750 mm.
 Free opening height 1900 mm.
