Passing HSTs at Ashbury Crossing, Shrivenham, on 14 July 1989. 43133 heads westwards with the 1B50 17:40 Paddington to Cheltenham Spa service, while the 1A70 17:30 Bristol Temple Meads to Paddington heads in the opposite direction. They shouldn't have been passing here at all, as while 1B50 is on time, 1A70 is running ten minutes late.
