Central Japan Railway Co. (JR Tokai) has announced that it will introduce a new Shinkansen bullet train model, the N700S, on the Tokaido and Sanyo lines in fiscal year 2020.
The nose of the new model is designed to reduce air resistance, noise and vibration when the train enters tunnels. The drive system will be far lighter than existing ones, a feature made possible by the use of next-generation silicon carbide semiconductors that JR Tokai co-developed with Toshiba Corp., Hitachi Ltd., Fuji Electric Co. and Mitsubishi Electric Corp.
The N700S will consume 7 percent less electricity than the N700A, which was introduced in 2013, a major Shinkansen model currently in use.
