As you may have seen from another recent post of mine, I have been looking into restaurant services on trains by using the Wayback Machine recently. One thing I wanted to ask about was the capacity of the restaurant cars on GNER. On their 225’s, they used a whole first class carriage which has 46 seats. On their HST’s however, they used the TFKB (Trailer First Kitchen Buffet) which has half of the carriage taken up by the kitchen and buffet counter, resulting in the carriage only having 17 seats. Given that HST’s are used on London to Inverness and Aberdeen services which, I would imagine, encourage people to eat in the restaurant given the length of the journey, was the capacity of the restaurant car on the HST sufficient or did it regularly get full? Did they use some seats in the adjacent carriage if required? Or, was the restaurant provision of the 225’s too generous and therefore they only used part of the carriage?
