Hi
Thats possible in Cities In Motion 2 game. Trams can use the metro tracks, but they cant use Metro stations in that game. Anyway, its a nice extra thing. When the trams runs on the metro tracks they also speed up like in real life.
Yes,… Ive taken the tramtrain around in Den Haag. Was a nice thing! Really! Also took Underground/Metro from Rotterdam to Den Haag. That was indeed cool!
