The newest prototype is a single rail car with an onboard engine and
employs a series-hybrid system with the future potential of being adapted
to fuel-cell-driven rail cars. The design incorporates regenerative
braking to further enhance efficiency.
The test train will be made up of a single car and carry two
65-kilowatt fuel cells, the report said. It can travel at 100 kilometers
(62.5 miles) per hour. The company plans to operate fuel-cell trains
sometime in mid-2007 on its lines in mountain regions west of Tokyo, the
report said.
The company has been working to develop rail cars that have lower
environmental impacts through innovation of the propulsion system, by
incorporating hybrid technology and fuel cell technology. Based on a
hybrid diesel-electric design, the original NE Train was the first step in
evaluating feasibility and energy efficiency of the new system.
The motor is powered solely by electricity when starting, and the
diesel engine starts during acceleration, generating additional
electricity. This electricity plus the electricity stored in the battery
drive the motors. A regenerative braking system also charges the battery
when braking, thus enabling the engine to be stopped while the train is
arriving at and departing from the station.
