 Both the Queen and Prince Philip were on board at the time, but were undisturbed by the accidental discharge, only becoming aware of it the following morning when notified by staff.Although railways often had nominated locomotives for hauling the Royal Train (with special high maintenance regimes), no locomotives were dedicated solely to the train until the 1990s, when two Class 47 locomotives were painted in the claret livery of the Royal Household and were dedicated solely to Royal Train duty until they were replaced in 2003 by two Class 67 locomotives, both operated by EWS (now DB Cargo UK).The new locomotives are often used for special charter train services and on other occasional passenger services when not required.
