[Suggestion] Auto Timetable

[TheOofertaffy]

It would be cool if we could set certain crews to apply certain timetables at set times throughout the day. For example, the player could setup a passenger train, and it would go along it's timetable, and once it was fulfilled, the crew would then autoswitch timetables to the defined one by the player once the time of day has been reached.

This specifically would help me for my Alarka branch passenger service, there it needs to frequently switch timetables when going to the junction, and back to the station when transferring passengers from the mainline express services I have.
