As I understand it, these sets are planned to be used until at least 2029 (!) before being replaced by actually new(er) trains that don't have "Leyland" logos above the insides of their doors, right?
Or, if they're supposed to be staying longer-term as "new-but-not-actually-new" trains (like the 230s and the Mark 4 sets) I think there are several things about their condition that are disappointing.
While the first one I travelled on a while ago, AT04 on a busy-ish service at a "normal" time of day, seemed fine...
...the second one I travelled on only the other day, AT02 on the early-morning 2M00 0448 Carmarthen-Shrewsbury, had several issues.
For one, the heating was faulty, apparently tripping on and off in 153528 according to the Carmarthen-Llandrindod guard, but not working sufficiently in 153353 either (granted, due to complicated circumstances - the same ones that were the reason I was travelling on that train in the first place - my top half was T-shirt-only, but still...)
Also, the interior engine sounds of the two vehicles were very different to each other. 153353's interior engine sound was completely normal, but 153528's interior engine sound was a very strange and relatively unpleasant sort-of groaning/straining sound that I don't know how else to explain, if anyone else knows what I mean, or what the cause of that would be?
Finally, there were interior condition issues on 153353, such as the wood grain-effect vinyl veneer missing from one table (therefore it had a bare Medium Density Fibreboard - or whatever - table top, complete with the stains you'd expect from the use of that), at least one rubber window seal that looked like it had somehow been chewed at, and ex-Arriva Trains Wales "Smile, You're on Camera" notices on some of the windows - would they be difficult to remove or something? (I'm not sure if the lop-sided moquette on probably a small proportion of the seats counts, but, although obviously not the end of the world, it's still not ideal from a quality standpoint).
I do appreciate the work that has been done (I know member(s) of the team that did it are on this site), and I know this is old equipment, but it would just be nice if the issues (or some of them) were "looked at"
