Diesel Hybrid

The World’s First Hybrid Train


・60% reduction in NOx and other harmful exhaust

・10% improvement in fuel efficiency

・30dB reduction in noise when stopped at stations

Diesel hybrid railcars offered by J-TREC utilize an innovative concept incorporating diesel engine generator and onboard storage batteries.

Electricity stored in the large lithium-ion batteries along with the diesel engine generator collaboratively work together to power the vehicle.

Combination of two power sources brings many benefits and advantages over the traditional diesel multiple units,
most notably in reduced exhaust emission, better fuel efficiency and quieter ride.

Vehicle maintenance can also be made simpler and easier by sharing common parts with electric multiple units 

Example Technical Specification

Diesel Hybrid – Regional Transport

    Passenger Capacity    117 (46 seated)
    Maximum Speed 100 km/h
    Hybrid Propulsion IGBT inverter control 3 phase induction motors 2x 95kW
    Lithium-ion batteries 15.2kWh
    Internal combustion engine 1x 331kW
    Generator 1x 270kW
    Brake System Pneumatic tread brake, regenerative brake feeding back to batteries, exhaust brake, security brake & parking brake


Battery Hybrid

EMUs on Non-Electrified Lines

Sustina Battery Hybrid

・Eliminating catenary and associated facilities for minimal groundside infrastructure

・Long traveling range with “charging stops” along the route

・Interoperable between electrified and non- electrified lines

Together with JR East, J-TREC has developed battery-powered electric multiple unit. Internal combustion engine is removed from the vehicle and large capacity storage batteries are installed instead.

With a pantograph equipped on the roof, the train is capable of operating on electrified line withpower supplied from catenary wire and also on non-electrified line from power supplied solely by the onboard storage batteries.
