[3] In 1837 the first Bill for a railway to Abingdon was laid before Parliament; it would have brought a direct line from Didcot to Oxford through the town.
[4] Located at the point where the branch diverges from the main line, Abingdon Junction was provided purely for interchange for services to Oxford, Culham and Didcot and was not shown in timetables.
[5][6][7] No proper road access to the station was provided and only modest passenger facilities were afforded consisting of two facing wooden platforms[8] with a small building constructed on the up main side and a run-around loop for branch services and connections with the main line.
[8] Following the conversion of the branch to standard gauge in November 1872, works began to extend the line a further ¾ mile northwards alongside the main line to reach a new station at Radley where it terminated in a bay platform on the station's west side.
The station building from Abingdon Junction was transported to Radley, where it was sited just south of the road bridge, most likely on the down side.
