A Chiltern Railways service towards Birmingham crosses the Oxford to Aylesbury freight line at Bicester as DB Schenker's 66232 crosses Gavray Junction and takes the new chord line to join the Chiltern Main Line which it will follow as far as South Ruislip. It is working empty aggregates wagons from Oxford to Acton Yard where they will join other empty wagons to complete their trip back to quarries in Somerset.
