Editing Timetable

First of all, great work on this sim.

Sadly I can only run the Grundolf map as the main map is too much for my computer. I was wondering is it possible to edit the timetable to allow more than one bus to run on the timetable?

I appologise if this has already been mentioned or this in the wrong section.

Cheers.

Load berlin with "load without busses" option, and it will be better. The default situation in berlin is bugged. I got 7 fps with that, but after i reloaded it without busses option i get 30 fps.
