Japan Develops the World's First Hybrid Railcar

Wednesday, November 7, 2007 Posted: 12:16 PM JST

East Japan Railway Company has developed a railcar equipped with a diesel hybrid system with the aim of "Reducing Environmental Burden." The hybrid system uses a diesel generator and rechargeable batteries to power its motor. In a world first on July 31, 2007, the company began commercial operations with this hybrid railcar on the JR Koumi Line (from Kobuchizawa in Yamanashi Prefecture to Komoro in Nagano Prefecture).

When the new railcar, the Series KIHA E200, starts, only electricity stored in the charged batteries powers its motor. When the railcar gathers speed, the diesel engine starts and electricity from both the diesel generator and the batteries are used to power its motor. When the brakes are applied, the diesel engine stops and energy is transferred to the batteries by using the motor as a generator. In this way, the engine is used only when a railcar gathers speed, so it is not necessary to have the engine run idle while a railcar is at a standstill.

Series KIHA E200, using the hybrid system, has reduced fuel consumption and boasts nearly 60% lower emissions of nitrogen oxide and particulates when compared with the conventional Series KIHA 110, which uses only engine power via a transmission to drive its wheels.

The now legendary Sir Ernest Mason Satow (1843-1929) was a member of the British legation in Tokyo for twenty-one years. This classic book is based on the author's detailed diary, personal encounters, and keen memory. In it, Satow records the history of the critical years of social and political upheaval that accompanied Japan's first encounters with the West around the time of the Meiji Restoration. Fascinating.
