I'm trying to run trains to a schedule (so I can have more trains in peak hours etc) but I've noticed a problem with the "orders" editor. I've got an order to run a "line" and told it to start at the first stop, timing (same as enter stop) and =, exit (last line stop), timing (depart exactly at) and a time. The line takes a set time including stack, in this case 75 minutes (there is some slack which is all at the first stop on the route). I've set the first train to leave at 06:22:00 and three repeats, so trains should leave at 6:22, 7:37 and 8:52. When I check the timetable, the first two trains are correct. But the last train leaves at 8:55:28. It looks like the last train on the repeat is being delayed by the amount of time it takes to get from the last station on the line back to the first. This applies if you just set one repeat too (as it's the last of one).
