there is a lot of over reactions in this thread. I have not tried a GWR set yet but have been up and down the East Coast recently in both First and Standard on the IETs. I had no problem with the comfort in either class and was impressed with the legroom in standard, yes there was a rough ride but over the same stretches the ride was just as rough in the HSTs and Mk4 sets so more an issue with the trackwork than the trains. My only complaint really was when i was on a pair of 5 car 801 sets on a Leeds service, i'm not sure how the air con works but there was a fair bit of what sounded like exterior noise coming from the ceiling area?
