Will the rail system support tunnels through the mountains? I would love to be able to see a scene like this in AH3:
If its not possible to place actual RR tunnels in AH3 terrains, would it be possible to create RR spawn/de-spawn points that look like tunnel entrances? That way, you could simulate a mountain tunnel by having the train disappear car by car as it reached the tunnel entrance, and then have it re-spawn, car by car a little later at the entrance to the tunnel on the other side of the mountain?
Will it be possible to lay dual track? As in, side-by-side tracks with opposite direction train traffic? Can each country have more than one train operating at a time?
