165001 races through Denham Golf Club station on 26 March 2017 with the 1H06 09:03 Bicester North to Marylebone Chiltern Railways service, passing the instantly recognisable GWR pagoda huts, once so common on Great Western lines, but now exceedingly unusual on the national network. Coincidentally, just over an hour later, another of Chiltern Railway's lowest numbered class members passed through, when 168001 worked the 1Y15 10:11 Oxford to Marylebone service.
