and, in 1927, it added a crossover between the fast and slow lines. This was to play a significant role in the derailment of Royal Scot No. 6114 "Coldstream Guardsman" at Linslade on 22 March 1931 when the driver took the crossover at 50–60 mph instead of the regulation 15 mph. There had been a diversion in place on the fast lines and the driver had missed the warning signals. The engine overturned and six people were killed, including the driver and fireman. The Scotland amateur football team was on the train, but remained unscathed. In 1957–1958 the platform buildings were rebuilt and a concrete awning placed over the platform. At the entrance a larger booking / waiting hall, central heating, electric lighting and the cycle storage, parcels and loading bay were improved. The Great Train Robbery of 1963 occurred just south of this station, at near Ledburn, at a bridge on the southbound stretch towards Cheddington. Wing Yard was closed in February 1967 and it is now used as a car park, while the branch to Dunstable was closed from June. In 1989, the platforms were lengthened to accommodate 12-coach trains and a £1.8m project to rebuild the station was started.
