Japanese Trains With Batteries

If Bombardier in Derby and the Germans in Chemnitz (Karl Marx Stadt to Jeremy and the Corbedians)  are addressing battery technology, you could be sure that the Japanese would have ideas and there is this article in Railway Gazette, which is entitled Emergency batteries for Tokyo Metro trains.

This is said.

Nippon Sharyo Series 1000 trainsets operating on Tokyo Metro’s Ginza Line have been fitted with Toshiba onboard emergency batteries so that they can reach the next station under their own power in the event of a traction supply failure.

Toshiba says the SCiB lithium-ion battery is well-suited to emergency use, being resistant to external shock, internal short circuits and thermal runaway. It recharges rapidly, has a long life and a high effective capacity over a wide range of environmental conditions.

The battery draws power from the third rail during normal operation, and can supply the traction system in the event of power outage or other emergency. It can also be used for train movements within depots.

I also said this in Bombardier’s Plug-and-Play Train,

I wouldn’t rule out that all Class 345 trains were fitted with some form of onboard energy storage.

The main reasons are all given in the article about Japanese trains.
