In TSW3, I had approx one minute to load passengers and leave, which was not enough. Most often, I would have to leave 30 seconds late, due to time it takes for passengers to load, doors to close, etc. I believe we asked for this to be extended. Just starting the last service in the first chapter on DRA, and I have 30 seconds only, and it takes one minute to load passengers. I will be late from the starting block. Thank you, DTG!
I believe newer routes are given more time, but older routes will maintain the current scheduled timetable. Because DRA didn't get a new timetable, I'm guessing the timings have not changed. You should see improvements with the actual new routes with newly built timetables.
