Not sure but I think it requires a bit of knowledge on scripting the game code.You could try giving driver commands such as "drive to station 1 & "load" to pick up passengers.
Have you tried running any of the routes that are included in TRS06 to get a feel for how the game works?
I'm not sure I understand what you are trying to do (to me timetables and waybills are very different things). Could you give us a better idea of what you are trying to achieve?
