In late 2007 the Cotswold Line was about to become a largely HST operated railway, although the class had operated a number of peak hour services over the line since 1984. 43177 is pictured here passing Chilson on 7 January 1989 with the 11:10 Paddington to Worcester Shrub Hill service. Unlike many of the First Great Western operated services today, which use exactly the same infrastructure and rolling stock, this train was running exactly to time.
