FGW wanted to remove buffets from all but the long distance sets in a move to try and improve performance by saving weight. After this proved impractical it decided to replace 15 buffets with mini buffets. It has since admitted this was a mistake and seeing that the 15 withdrawn buffets are being returned to service, albeit rebuilt as TSOs with the benefit of hindsight it would have been better sticking with the status quo.
Ahh, i see, thanks for that. It has been argued by many a manager on EC that trolleys take more revenue than buffets which may be true when both run, however i will always argue back if that you had to choose one or the other the buffet will always take more than just a trolley would.
