junction between the Great Western Main Line (GWML) and the route to Oxford and the Midlands. A marshalling yard is opposite platform 5 and another was once provided at Moreton, a little to the east. Moreton is still a junction, allowing trains to pass between the main lines on the south, and the relief and Oxford lines on the north. An avoiding line runs from Didcot East Junction, behind the marshalling yard and the Didcot Railway Centre, allowing trains to Oxford to run through without blocking the station platforms. There also used to be another line at the East Junction which led to on the former DN&S railway. The track was lifted in 1967. The junction at the west end of the station which is accessible from platforms 3, 4, and 5 (the Oxford bound platforms) is known as Chester Line Junction.
