Sticking titanium shoes on a carthorse is all very well, but it still
cant
draw a 4,000 tonne train.

A diesel engine can.


When there is fuel to run it.

Which there always will be. We already have the technology to
manufacture it from waste products, water and sunlight. It is only that
it is not economic to do so at today's prices.


yep. Carbon fuel is the ideal storage medium as a 'battery' Its just
that there are - so to speak - a lot of AAAs lying around ready charged
under the ground.

And the cycle efficiency is crap.
