While it would help, the electricity requirements for electric
traction of vehicles are massive.
I was surprised to read that the huge solar array on the roof of the
new Berlin Hauptbahnhof station will generate at most 5% (five
percent) of the station's electricity needs - though with hundreds of
electric trains calling every day, perhaps it's not surprising at all...
I have been involved in an informal railway think piece for years,
and we've not managed to work out how to generate a railway's
electricity requirement "internally" without large amounts of extra
land for wind turbines and biomass burning. I believe even to supply
diesel trains with biodiesel will require a huge investment in
processing facilities as those that exist already are stretched to
