A marshalling yard was opened to the west of the station on 30 July 1946.
It was used for many years by the British Railways' Civil Engineer and was home to a Ruston and Hornsby 0-6-0 diesel shunter, PWM652.
After the end of this permanent way work the sidings were little used, mainly being a place to store unwanted or damaged wagons.

During 2006 they were relaid and in January 2007 were returned to use.
Fairwater is now the home for a High Output Track Renewal System.
This is engaged on renewal of track on the Great Western Main Line west of Swindon, the Reading to Exeter Main Line and the Bristol to Taunton Line.
The equipment based in the yard at that time was a Plasser and Theurer High Output Ballast Cleaner, a Matisa High Output Track Renewal Train, and smaller on-track plant.
The Matisa Track Renewal Train was removed from Fairwater Yard in April 2012 after it had completed its need for use in the South West.
