fantastic idea, however....

I don't think that standard factions should get them.

Perhaps Aulé created these in the beginning and they were broken and their parts were strewn over ME during the First War with Melkor? Then you could find parts in ruins? (however, i think that the dwarves could have 'rediscovered' them & also as some of the legendary hobbits (Isumbras?) traded with the dwarves, they got the parts and made them?)

The trains would naturally have to be clockwork/steamy to have even an inkling of time period.

THese trains would be extremely useful if a player spanned them over Rhún!

I think that the goblins and those of Isengard should also have trains but more crude-looking like you mentioned, perhaps look at Warhammer 40k for inspiration?

Having different carts behind would be very cool - eg barrel carts which can hold 4 barrels?

anyways, a brilliant concept!
