Wainhill Crossing Halt was a halt on the Watlington and Princes Risborough Railway which the Great Western Railway opened in 1925 to serve the Oxfordshire hamlet of Wainhill. The opening of the halt was part of a GWR attempt to encourage more passengers on the line at a time when competition from bus services was drawing away patronage.pened in 1925, the halt - the last station to open on the line - sought to encourage passenger traffic in the face of increased competition from buses. It was situated to the south of a level crossing over an unclassified road leading to Lower Wainhill and Hempton Wainhill. The lane saw very occasional traffic as it was unsuitable for motor vehicles and only served nine or ten houses on the eastern side of the Watlington and Princes Risborough Railway.
