I don't know if this has already been reported, but if so, just ignore it. Today I did a short service on SPG (Y101 at 9:05 am) and started it in journey mode. The game put me in a SD40-2, everything ok. I finished this service without any hassle, but the debriefing made me wonder. The APs from this service were credited to the GP38-2, and this should be considered a bug. Then I was getting curious and checked the timetable mode, where this service is available for both locos. That may be part of the problem.
