37419 Agamemnon passes Uffington on 1 October 2026 with the 1Q23 06:43 Bristol Kingsland Road to Derby RTC Network Rail test train. 37422 Pegasus is bringing up the rear. This was running 24 minutes late, after a longer than booked stop at Swindon. This late running was worrying, as although at the booked time there was hardly a cloud in the sky, by now there was masses of clouds, and I was lucky to get this in the sun.
