Running 65 minutes late, after a 99 minute late departure from Derby, 37175 passes Churcham on 19 February 2019 with the 1Z97 09:39 Derby RTC to Cardiff Canton Sidings Network Rail test train. 37418 is bringing up the rear. I was really surprised to get this in the sun, as an hour earlier the forecast mass of dark clouds had rolled in from the west, and I thought that was it for the day. Literally just a few minutes before this was due the sun reappeared.
