165010 & 165034 pass underneath the Chiltern Line at Gavray Junction on 10 June 2018 with the Branch Line Society 'Sopwith Camel' railtour. I'm not quite sure what headcode this is running under, as the 1Z17 15:40 Aylesbury to Bicester Signal OB1792 took it to just out of sight behind the bridge, but the 1Z18 17:10 Gavray Junction to Aylesbury obviously starts a few yards further on! This complicated itinerary saw it visit Bicester Village station twice within a few minutes. Apologies for the schoolboy error of taking this picture from the shadow side, but that was the only way possible to record this unusual move.
