A stranger on the Cotswold Line! Prototype Class 230 DEMU 230001 crosses over from the up to the down line at Moreton-Marsh on 6 July 2017, after arriving with the 5Z30 09:40 Long Marston to Moreton-in-Marsh test run. After a brief wait in the station, it would head north with the 5Z31 10:30 Moreton-in-Marsh to Long Marston. The event was so noteworthy that one of the track workers by the signal box went back to his van to get his camera to record the event!
