Current/Prev location

I've had a couple of TCFs which I had to work around by abandoning the timetables of some trains. I've noticed that, even though they're still moving around (off timetable), the 'Current/Prev location' field on the train list sticks at where they were when I abandoned the timetable - I'm fairly sure it keeps updating on other sims.

Perhaps relatedly: one TCF was stopping trains on the Down Camp Hill from turning left at Bordesley Junction, just as I got a load of class 5s from New Street going back to Tyseley. I parked a few of them up around Duddeston and Landor Street Junctions to keep them out of the way of other trains on the Down Camp Hill. Now the track circuit has been fixed and I'm starting to move them again, they're all phoning in 'incorrect route'. Interestingly I hadn't abandoned these from their timetables, just reversed them, but now I have because answering 'Bypass Bordesley Jn and then keep to timetable' doesn't seem to work.

If you reversed them have you A> turned them back to travel in the correct direction again?

B> checked that Bordesley Junction is their next location otherwise they would be trying to reach whichever location is next on their timetable prior to "Bypass Bordesley Jn and then keep to timetable" kicking in.
