British Rail
Long-distance trains from Marylebone began to be cut back from 1958 after the line was given from BR Midland Western to the BR Midland Region. Then BR Midland Region thought it was an unnecessary rival of their Midland Main Line. By 1960 there were no daytime trains running to destinations north of Nottingham and only a few still ran at night. Many Express services were cut. By 1963, local stopping services beyond Aylesbury were cut. In 1965 freight services were ended. Between 1963 and 1966 only a few remaining long distance services stayed in use. A large part of the former Great Central Railway was closed as part of the 'Beeching axe'. This meant that Marylebone was now used only by local trains to Aylesbury and High Wycombe. After the 1960s, lack of investment meant the station itself became run down.
