As of August 2023[update], construction of a new station nears completion and is scheduled to be served by East West Rail, as part of the plan to reinstate the Oxford–Cambridge service.

[6][5][8][9] The line was subsequently extended westwards to Islip, to a temporary station at Banbury Road and then to Oxford, opening throughout on 20 May 1851.

[19] Architecturally, the brick station resembled the stone structure provided at Bicester Town, particularly its twin symmetrical gables covered by ridge tiles and its portico.

[21][22] A stationhouse was also provided for the stationmaster and this was situated just beyond the main station building and arranged around a circular driveway at the centre of which was a large horse chestnut tree.

[19] In the wake of the abandonment of a plan to develop the Varsity Line as a freight link from the East Coast ports to South Wales, including a marshalling yard near Swanbourne, Winslow station was listed for closure in the Beeching report[28] which called for the closure of all minor stations on the line.

[29] This followed the introduction of diesel trains in an attempt to reduce operating costs after a failed proposal to close the line, which had been put forward in 1959 but successfully resisted by local authorities.

[29][30] With the line's expenses amounting to £199,700 against a revenue of £102,200 in 1964,[29] Winslow duly closed to goods traffic on 22 May 1967[31] and to passengers on 1 January 1968;[3][4] the signal box followed one month later.

[4] The station building, which was by then in a very derelict state, survived long enough to see the first visit of a Class 43 on 13 February 1993, but was demolished very shortly afterwards.
