37116 passes Kemble Wick on 24 November 2020 with the 1Q15 06:50 Derby RTC to Swansea Network Rail test train, with 37219 bringing up the rear. This had been running late all day, but when the sun started to come out, I decided it was worth a look, and hoped by the time it got to me it would have recovered some time, as it often does. Unfortunately it just kept getting later, and was running 71 minutes late here, and the sun had long since disappeared!
