Development of catenary and storage battery hybrid train system

East Japan Railway Company has been developing a catenary and storage battery hybrid train system to decrease negative environmental impact by diesel trains operating on non-electrified lines. A quick charge test and final running test have been under way since the beginning of 2011. The functions of the catenary and storage battery hybrid train system on a non-electrified section and an electrified section and the results of test runs are shown in this paper.
