Re: Hydrogen storage
A proof-of-concept ran not that long ago. In that one the hydrogen was in cylinders in the coach but it would be easy enough to get them underneath or go back to the traditional locomotive format.
With all these things starting at the bigger end is often easier as size and weight is less of an issue.
Most of the diesel powered passenger trains have a crappy bus engine buzzing away under every carriage because it was "cheaper to maintain". Now for short two or three coach units it probably makes sense but for all the long distance trains it has to be less economical.
