do any one here have any info about the new electrical multiple unit indian railways is developing cpable of 220 km/h
here are its specifications...
While MOR conducted study of upgrading existing lines with
speeding up of loco-haul passenger coach (PC), the Consortium
proposes EMU train for upgrading of existing line for the
following reasons.
a) Light axle load : Damage to track will be reduced, and hence
longer track maintenance interval can be expected.
b) High redundant system: One traction unit failure will not
cause operation disturbance in entire line, because EMU
train can continue running by other traction unit with cutting
off failed traction unit.
c) Higher acceleration and deceleration performance: Schedule
speed will be higher and stopping distance will be shorter.
d) Profit from regenerate braking : Regenerated electricity to
be supplied to over head line will be efficiently used and
mechanical wear of pneumatic brake will be decreased.
Specification of the Proposed Train
Train Configuration 8 cars/train
Train set MT ratio 6M2T or 4M4T
Train set length Approx.200m
Car body length 26.4m(Front-end car)
25m(Intermediate car)
Car body width 3,380mm
Car body height 3,700mm
Max. Operation Speed 200km/h
Passenger Capacity Approx. 575persons/train
Train Weight (Unladen load) 400ton/train
Maximum axle load Approx.14ton
Acceleration 0.4m/s2

High-speed train sets for Rajdhani and Shatabdi Expresses
NEW DELHI: Aiming at reducing travel time in train journey, Railways is acquiring Electrical Multiple Units (EMU) train sets for premier services like Rajdhani and Shatabdi Expresses for operating at a higher speed of 130-150 km per hour.
The decision to adopt train sets technology was announced in the 2012-13 Railway Budget.
"We are working on introducing modern EMU train sets designed for operations at maximum speed of 130-150 kmph for running premium Rajdhani and Shatabdi trains, without any additional expenditure on existing track and signalling infrastructure," said a senior Railway Ministry official.
According to the official, existing rail tracks on Rajdhani routes are fit for running trains up to a speed of 150 km per hour, but average speeds of Rajdhani/Shatabdi trains is less than 90 km per hour due to large number of speed restrictions and poor acceleration of existing loco hauled trains.
The Railways are expecting that the proposed modern distributed powered EMU train sets will be free from these bottlenecks, provide faster and safer movement and will substantially reduce running time.
The proposed EMU train sets consist of 21 cars (coaches) and are estimated to cost about Rs 200 crore per train.
The Railways claim modern train sets are eco friendly, noiseless, consume 30 per cent less energy and do not pollute the environment as in case of conventional loco hauled trains.
