can´t you just clone the aircraft code to make it work as trains?... to add it into AM, not to develop a new game
Aircraft dont follow fixed routes as such, trains do. Very distinct difference that changes the entire concept of the game. 
I don´t get it, what´s the difference between a virtual lisbon-madrid route and a skyline route?, isn´t it a simple "a to b" route thing?
don´t mind answering, I would be wasting your time with tons of questions :wink:
