Regular users of Class 175's will know that the seating is exceedingly comfy (I believe the seating is similar on Class 180's). Could this seating be replicated in Standard Class on other trains, such as the 185's, 220/221/222's, 350's and 390's? Perhaps on even more Classes? The 350's and 185's in particular serve a very similar purpose to the 175's - they serve plenty of short distance passengers, whilst also serving a good number of long distance passengers. The seating on 175's is ideal for both categories of travelers, and whilst the seating on 185's and 350's is "adequate" for short distance passengers, both are not at all ideal for long distance passengers! Much too hard... What do people think? Could this be feasible when each Class goes in for a refurb in the next few years? PS. Please don't comment if you have no experience of the 175's! Thanks.
