This is where the mainline from Marylebone diverges into two main lines: the Chiltern Main Line, which runs towards High Wycombe and Birmingham, and the London to Aylesbury Line. The Aylesbury Line used to be the main route of the Great Central Main Line, until the Chiltern Main Line was built to replace it, rejoining the old route north of Aylesbury. The Great Central ran to Rugby, Leicester, Nottingham, Sheffield and Manchester until it was closed due to the Beeching axe in 1966.
