In 1975 the London-South Wales railway line was closed between Wootton Bassett and Westerleigh to allow upgrading in readiness for the introduction of the High Speed Train, or Inter City 125 as it became known. This meant that the traffic had to be diverted via Bath. Trains then took a right just before reaching Temple Meads Station in Bristol and proceeded north through Lawrence Hill, Stapleton Road and Filton Junction to regain their normal route.
Here the 1315 London Paddington-Cardiff train, a regular working for Class 52 locomotives almost until their demise, takes the curve to join the line north out of Bristol at Dr Day's Junction. Monday 19th May 1975.
