Mine. You've said "any route". So it's GCC then only? Cathcart has depot moves only for the 385 anyway, no services hence no PIS. It would need Cathcart having PIS info for Edinburgh e.g.
Quick check, AI service to Alloa OK Make some more checks and refine your bug report so it's reproducible. (Of course, I am not on Xbox and results may be different on my end.)
Can anyone reproduce the issue on Xbox Series S/X with the broken PIS on AI Trains it’s Worked only for my own 385 Train when i start a Journey or timetable but Not for the AI
