Your first class All Line Rover doesn't count towards qualifying, in case you were wondering.
By the way, I thought there is a vast overprovision of first class on Pendolinos, the accommodation is always empty, converting Coach G to standard class is not enough and it would be best to convert Coach H too leaving only Coaches J and K (55 first class seats, down from 99 with H, down from 145 with G). Right? Right!?
In my experience, 9-car Pendolinos popular with business travellers operating pre-10am arrivals / 15:00-18:45 departures at Euston, which don't call at Milton Keynes, tend to be more densely populated in first class than standard class. Sometimes full in first with plenty of seats of standard. 9-car Pendolinos have 370 standard class seats, 99 first class. They had 294 standard class, 145 first class before Coach G was converted to standard.
11-car Pendolinos have a good balance of 444 standard class and 145 first class seats, which is how all Pendolinos should have been had the DfT not been cheapskates when lengthening them.
