do you have any clue as to how much a train weighs? how
much HP is needed to move one?But of course I do,

The idea is to use conventional trains and use the sails to assist.

Electric trains can generate about 30% of the energy used to accelerate
while breaking.

If (on average) we could shave of (only) an extra 10% the sail would
already be interesting.

For now I think solid sails are the best solution, I've updated the
page a bit.
