On the RB 6465 service for the DB 110 in timetable mode starting at 15:57, there is an AI service with a DB 110 on the platform adjacent to you when you arrive at your first stop about 1.5 km from your starting point. This service will not move from this spot, and other AI services going that direction will begin to stack up behind it. You can still complete the RB 6465 service but I imagine if you grabbed another service in the other direction in the same session then your way back would be blocked. I know you can use free roam tools to remove the offending service but I figure it's still worth bringing attention to.
