Cheddington was formerly a junction for the LNWR's branch line to Aylesbury High Street. This branch terminated in the east of the town and made no connection to the GCR/Metropolitan Railway station in Aylesbury. It closed to passengers in 1953 (freight continuing until 1964); however, the branch platform is still in situ at Cheddington and the curve of the branch is now part of the station's approach road.
