Battery powered trains can actually add a lot of flexibility to rail infrastructure.
Having worked on railways all over the world from small city metro to Shinanksen HSR, the vast majority use overhead catenary wires. However this is by no means cheap or simple. The power subsystem is often one of the most expensive and complex, especially since most also use regen power to feed back in to the network.
An on board battery would most likely be used in a hybrid situation. You run HV catenary for a few KM to charge the battery, then run on battery to the next catenary section. You can then charge the battery when breaking rather than reverse feed. Also not having to connect the catenary sections over long distances has a lot of advantages in terms of power management.
