Looking at my list of 197s the one and only time ive been on 197003 was January 2025. So it certainly hadnt been around for a long while. I assumed as it was a Cambrian 197 the reason it has been out of service for so long is because it was being stored, but it appears the other Cambrian 197s are being cycled as posted by @Gordonman but it being absent for so long does make me wonder if there are issues with it rather than it just being stored.
I know 197004 was out of service for a long time but came back into service recently and 197110 and 197045 have been out of service for ages.

I can't see the schedules, but I take it you can see them internally but they haven't yet "gone out"?
