That is an interesting alternative.

You need a battery that tolerates many many cycles, and being charged at 100x its usual discharge rate. Maybe a molten CaSb battery, from Ambri.

I guess if all the cars can be wired to take in power, you just need a short stretch of 3rd rail at each charge point, say 60 m, not 1600. If each car has its own battery and drive motors, they don't need to be wired together. Relative charge rate goes to 10,000x, but the grid load stays the same.

It's cheaper to just electrify the gaps. His views are fundamentally nonsensical and shows that he hadn't really thought about the problem. Hydrogen trains are for remote tracks, sometimes thousands of miles of unelectrified rail. If you can't justify ever electrifying those tracks, then hydrogen trains are the obvious answer.

Ammonia trains might be a better answer.
