West Japan Railway to launch diesel hybrid train in 2015
WJR's hybrid train combines a diesel engine with lithium-ion storage batteries. Those batteries, which are recharged by energy produced when the train decelerates, are used to power the train's lights, climate control systems and other accessories. According to WJR, the diesel electric setup boosts fuel economy by approximately 13 percent.
Since 2009, WJR has been field testing prototypes of the diesel-electric train. The trials have verified the hybrid system's ability to reduce fuel consumption, convincing WJR to give the train the green light. The next step is to settle on critical design features, such as where to locate the batteries and whether or not to make the trains charge-by-wire capable.
