With "IT" what do you mean specifically? And how did you come to this
conclusion?

Are you referring to public transport? :-)

So far I think it's a good idea to use the trains we already have to
transport the passengers. I was thinking to make sails the same width
and half the height of the train. Put them in sets of 4 on their own
set of wheels. carts to the front and rear end of the train. The
amount of carts you take with you depends on how brutal the wind is
that day.

The carts don't have to be heavy if they can be clamped onto the rails.

I imagine 60 mini sails could pull a reasonable size train or at least
help pull it.
