The train currently consists of nine carriages , seven of these being of the British Rail Mark 3 design , including two that were built for the prototype HST train . Not all of these are used to form a train , as different vehicles have specified purposes . Two locomotives are designated for use on the train and painted in the claret livery of the royal household , but are used for other traffic when not hauling the royal train . The carriages may be used for other Heads of State , but they can not be hired by private users . It was used to convey officials to the 24th G8 summit in May 1998 . When not in use , the train is stored in Wolverton Works , where it is maintained by DB Cargo UK
