Hey there, first of i highly appreciate your work for the mod as it helps me alot at gigabase level, so thank you very much!
To the problem: Right now you are just getting the information for the amount of trains to be build from the stationname, have you considered coding the whole request in the name? Sort of 1 3-9-3 for 1 Train consisting of 3 Locos front, 9 cargowagons and 3 Locos in the back!?
