43037 bursts out from under the bridge at Hay Lane near Swindon on 15 September 1979 whilst working the 13:45 Paddington to Weston-super-Mare service. Hay Lane was once the site of a temporary terminus for the Great Western Railway during the course of its construction between London and Bristol, nearby Swindon being only an insignificant village at the time. Between 17 December 1840 (when the line was extended from Challow) and 3 May 1851 (when the extension to Chippenham was opened) this remote spot was a hub of railway activity.
