I set up the rail roads and the train and the lines path and schedule but it doesnt work. it says this combanation wont drive. please help cause it sounds like a fun game.
Your train is built wrong way. The train must have a locomotive to run.
Passenger & Post trains can have an special locomotive that can be bought on Passenger & Post tab.
And check the convoy max speed.
It seems like missing locomotive.
An_dz tells truth - but not fully - and some trains have special locomotive that can be bought in Electrics tab.
Pay attention to colour bar that is under each vehicle. If any vehicle has green-yellow bar under itself, it means that some other vehicles have to be added. Some ones are added automatically (if only one car can be added) - and some not (if more cars can be added). But for this I have not any usable screenshot.
But else I agree with An_dz that your train probably has not been motorized - it has not engine (locomotive).
ya I was missing the locomotive thanks everyone.
