They're in such a state now; while everyone's entitled to their own opinion and I don't have anything against anyone personally, all the comments saying they're "the best" and "nice" are utterly baffling! I'd agree if it was still 2021, but not in 2025.
I really am looking forward to riding on one of the refurbished East Midlands Railway 158s sometime (even though, again, I think these trains shouldn't stay in normal service for more than about 7 more years).
Personally I don’t find that at all with the TfW 158s, which I travel on fairly regularly. They certainly show some signs of minor wear but are still a high standard overall from what I see.
