Both of the HRR trains (BR 425 and BR 422) have strange lighting effects from time to time (multiple times per service). They are mostly seeable on the desk but I also saw the floor having these issues occasionally. Here are a few screenshots of the issue:
It also has these strange effects on PS4. I don't remember this happening in TSW 2020. Maybe something that happened when the route got preserved? Hopefully it get fixed when the preservation team gets to HRR.
It seems to be a similar effect like that in the cab of the Baby Bullet (MP36PH) on Peninsula Corridor.
