43131 speeds past Bremell Sidings (near Swindon) with the 1B46 17:03 Paddington to Cheltenham service on 19 July 1990. The early repaints into the Intercity 'swallow' livery had tiny numbers which made identification at speed extremley difficult. The minute number can just be seen on the off white panel behind the radiator grilles. Surprisingly, given the seemingly non-stop march of Swindon's expansion, the houses on the horizon still mark the limit of the town's development two decades later.
