I travelled on 350401 on a lightly-loaded service (BHM-BHI) so managed to get some interior photos.
The pantograph (intermediate standard) car has two lavatories and a cycle space and, as a result, has lots of inward facing tip-up seats. Not suitable, one would think, for Euston-MK-Northampton commuters - whoever thought that arrangement acceptable on Anglo Scottish trains?

And here's the first class. Perhaps LNwR are ashamed of it; there is no reference to it being first on windows or doors. Presumably one of the sliding doors was dropped during the modification, the obscure glass being replaced by plain glass. Can't be extravagant.
