I think in Germany they did some tests with hydrogen trains and came to the conclusion that catenary electrification is cheaper in the long run and also more efficient, so greener.
Interesting. Do you know, if they added the creation and maintenance into the the calculation of the catenary lines?
So I was a bit wrong, they didn't come to the conclusion that full electrification was cheaper, but that battery trains with catenary islands are cheaper to operate than hydrogen. If they really added everything to the calculation I can't really say, but I hope so.

Thanks for looking it up, i appreciate it. As i understand it the main discussion is about the price and not which of them are greener. But i see the versatility of rechargeable batteries - you don't need to have contact wires everywhere.
