Varsity Line

The Varsity Line (or Oxford to Cambridge Line) is an informal name for the railway route that formerly linked the English university cities of Oxford and Cambridge, operated successively by the London and North Western Railway, the London, Midland and Scottish Railway, and British Railways. A pun on the railway term main line was sometimes employed by describing the line as the "Brain Line".

Services were withdrawn from the Oxford - Bletchley section and the Bedford - Cambridge section at the end of 1967, even though the line had not been listed for closure as part of the Beeching Axe in 1963.

The only sections still in regular passenger use today are the Oxford to Bicester Line from Oxford to Bicester Town, and the Marston Vale Line operation from Bletchley to Bedford. The Bicester - Calvert section still carries freight traffic but the Calvert - Bletchley section, though extant, is currently disused. There are well-developed plans to open a short section from Bicester Town to the Chiltern Main Line as part of Project Evergreen 3 and from Bicester to Bedford as part of the East West Rail Link.

In the absence of a through rail service, Stagecoach in Bedford's X5 coach service provides a passenger service by road between Oxford and Cambridge via Bicester, Milton Keynes and Bedford.
