DB Schenker's 66232 approaches Gavray Junction at Bicester with a train of empty aggregate wagons from Oxford to Acton. Both tracks are signalled for trains in both directions and this one has run 'wrong line' all the way from Oxford to allow a passenger service from Oxford Parkway to run on the usual track. It will now switch to the left hand line before it joins the Chiltern Main Line but a passenger train from London is already waiting at a red signal at the junction for this freight train to get out of its way.
