Yes the high density tombstone seats on the GWR HSTs made for a horrible travelling environment. The IETs are much nicer to sit in, if only they would sort the seat bases!I agree. I hate to say it but the carriage ambience is better than the old GWR HSTS with the high backed seats. But the actual seating on IETs needs addressing as with age it has got ALOT worse. There was this idea 5 years ago that the seating would get more comfy with age as more people sat on it softening it up. However the opposite has happened and the base of the cushion on many many seats has worn down to the point it is uncomfortable for 5 minutes, let alone 5 hours. The question is, will anything get done about it?
