Yes, I perfectly understand how difficult it is to implement, but I think in any case it would be better and more realistic than just fast movement, and you can make a map with ready-made railway tracks on a prepared map, it seems like the game already has several ready-made maps, but at random on the generated maps, the paths would be laid by the players.
Yes, but the game already has a car, a motorcycle and a gyroplane, so a moving train is of course a dream, but definitely not a fantasy
