I still think that to replace some 7 and 8 coach sets with just 5 is a mistake. Yes, these 5-car Class 804 units will have more standard seats, however peak hour services formed of just 5 cars will go from having more than 100 first class seats (7-car 222) and similar for 8-car HST to says 36 or 48 maybe? (which is the GWR and LNER 5-car Class 800 provision) which won't be enough. plus 5 car compared to 7 or 8 has less standing room, luggage storage, bike storage etc. Simply put 5-car services in the peak hours will struggle.
