Re: Not as green as 25kv overhead
Why not try using an overhead wire (as in a trolley) to provide electricity to the train?
This electricity could be used to "crack" water (Hey! The oceans ARE FULL OF IT!) provided to the engine, in much the same manner as was provided to Steam Engines 100 years ago. Don't knock this. - it is tried and proven!
The H2 could be used to power the fuel cells with their exotic platinum catalysts! These would then drive ELECTRIC MOTORS at each wheel! Any oxygen produced (I'm told there may a bit of it) could be captured, bottled, and used to treat elderly people with asthma, and those unfortunates with Covid-19.
It's a Win-Win-Win-Win! And a 5th Win for good luck!
Suggest this method to your local politician or MP. I bet
he.. uh, she will most certainly go for it! After all, It's HYDROGEN!
