The 125 Group 1Z43 09:12 Paddington to Swansea 'The Journey Shrinker' railtour passes South Marston on 3 October 2026, with 43025 Exeter leading, and 43159 bringing up the rear. The tour was organised to mark 50 years (almost to the day) of Western Region HST services. The official launch was on 4 October 1976. Luckily 800006 & 800007 with the 1A14 09:30 Bristol Temple Meads to Paddington GWR service have just managed to get out of the way in time!
