While I accept that they have been somewhat unreliable at times, I am disappointed that the current Red Arrow fleet is to be replaced - I find them to be very comfortable, quiet and pleasant vehicles in which to travel and to some extent they do justice to the premium TrentBarton charge for the service. Having said that, whatever the Yutongs offer I will continue to use the train between Derby and Nottingham when its feasible. This is because on most occasions CrossCountry advances are available at very short notice, and with a rail card they are usually much cheaper than the exorbitant (by comparison) cost of a ZigZag when I only need to do a return between the two city centres.
