Parliamentary authority to extend the Wycombe Railway's single track line beyond Princes Risborough to Oxford was given on 28 June 1861.

[8] A single siding equipped with a 2-ton yard crane handled goods traffic which consisted of watercress and English elm boles for trawling nets made locally in Longwick.

[11] On the basis of an estimated saving of £34,372, British Railways withdrew passenger services between Oxford and Princes Risborough from January 1963 but the line remained open for freight traffic.

In September 1965 Bledlow level crossing was converted to automatic half-barriers[12] enabling the signal box to be closed.

[13] Freight traffic was withdrawn and British Rail closed the line between Thame and Princes Risborough in October 1991.
