 The station was entirely rebuilt by the Metropolitan Railway which doubled the line and provided a Down platform which partially obstructed the line of sight from the signal box.Winslow Road saw little passenger traffic, which may be attributed to its location a little over a mile from the village of Winslow which it purported to serve and which had its own conveniently-sited station on the Oxford to Bletchley line since May 1850.During 1939, work started on singling the line south of Winslow Road, with the double track left on a section from a pair of stops near the station to Verney Junction.
