I only have a few hours until now, really like the concept. However:
As a dispatcher, I find the timetable view to be pretty useless, unless everything runs on time and without issues. In my opinion, it should be possible to edit the cells (locally, not shared with other players in any way), especially the cells for Real Arrival / Departure, which should start out empty, allowing them to be filled by the dispatcher once the train actually arrives/departs.
