With the closure of the Oxford to Bicester line for major engineering works in connection with the new link to the Marylebone line, the Didcot to Bicester MoD train has had to take a massive detour via London, stretching the normal 50 minute trip to not far short of five hours! A Network Rail worker carefully watches the recently installed point (clipped for the passage of this train) at Gavray Junction, Bicester, on 19 June 2014, as 66115 gingerly negotiates the new trackwork with the 6A49 07:32 Didcot to Bicester MoD stores. In the background 70802 waits with a ballast train.
