37254 Churchill Heath 2 November 2022

37254 Cardiff Canton passes Churchill Heath on 2 November 2022 with the 1Z22 06:44 Derby RTC to Bristol Kingsland Road Network Rail test train. 37421 is bringing up the rear. Very noticeable in the gloom as it approached was the bright light on the roof of the third coach, used to aid visual inspection of 25kV overhead electric wires. Clearly there is not much need for that on the Cotswold Line!
