37254 Cardiff Canton passes through Ascott-under-Wychwood station on 4 October 2023 with the 1Z22 07:49 Derby RTC to Bristol Kingsland Road Network Rail test train. 37175 is bringing up the rear. Apart from the RHTT running in darkness in the early hours, this was the only train to traverse the Cotswold Line on this day, due to ASLEF strike action. Consequently, with nothing to get in its way, this was running 42 minutes early. With no other trains, the signalman in the box in the background had an easy day!
