This is the same issue that some players experienced a few months ago where you'd pick a service and it would load you in at a station miles from where there service started and not in the loco. I paused and clicked the restart button 3 times and the issue didn't resolve. This is on the 13: something 08 pilot service at Penzance. I think the month was July with clear Weather.
I did that but selected a different service and it worked. It's just annoying when this sort of thing happens. What with all the crashes and bugs of rush hour I've ended up spending a lot of time loading in and out of things
