I would like to see a possibility, to build Tracks on a Wall, like here:
This would make it much easier to build tracks in urban areas. When this would be implemented, I would like to see, that the game instead of RR crossings make a bridge over the street. The possibility to buold the tracks on a wall should be choosable like the type of RR crossing or like a bridge. I also would like it, if the game could show me, when I’m in the right high to cross another Railway or when I have to switch from going up to straight to have the perfect high for a bridge over another track.
