Here is how I see Multiplayer maybe happening in TS but not sure how everything would work. I am going by how the game is right now. 1. First everyone that would enter a Multiplayer session would have to have the same trains and the same route, unless it was possible to create regions. For example a German region that connects all cities together. I am mainly focused on Passenger trains but Frieght could go where every yards are created. 2. The Network could have people acting as route and Junction controllers this way a load of traffic could be organized and managed. 3. The Network could display somehow the routes that each player is taking. For instance if I go Frankfurt to Koln then it would display something like this. ChooChooKeith ICE3M Frankfurt Pl 1 to Koln Pl 5 it might give waypoints as well which would be neat like a timetable board. 4. When you connect to the Multiplayer session you need a way to place the train on the platform that you are leaving and arriving. 5. Voice/Communication. this could be apart of the network or a 3rd party audio app that would allow you to communicate with other players. please add anything else to this and again I am just throwing things out there and I really do not know what can and cannot be done.
