A complete ex-works HST set, led by 43169, approaches the site of Ashbury Crossing, Shrivenham, on 14 July 1989 with the 1C70 18:17 Paddington to Bristol Temple Meads service. This was only booked for a HST on Fridays, and was loco hauled the rest of the week. Was this a regular running in turn for ex-works HSTs?
