Right, my bad. I should have looked more into that. I just got some nostalgia, there are lots of game that have trains, but as Atomix said a lot of them won't work.
That is almost impossible without thrusters. One of the fastest trains only goes 442 kph, so it would be unrealistic. Anyway, I am going to dream about what I could do when this is done.
Im not gonna lie the work effort put into this would be immense and i really appreciate this as i have been looking for a train mod since i got the game thank you
