It looks like in that coach it's just four tables. That is just wrong - why do designers have to make a train interior like an airliner? We had the mk1's,2's and 3's (was there a couple of two's?) with just tables and bays, and we managed fine, a pleasant airy environment. This looks cramped - wouldn't be so bad if the seat backs weren't so high and the headrests tapered in at the top. It puts families off traveling by rail if they can't sit together.
By all means have perhaps a third of the coach two's, spaced out, but not this many - how many bays with tables are there in the other coaches?
