43084 County of Derbyshire leads the 1M25 16:16 Bournemouth to Manchester Piccadilly service past Cholsey on 22 July 1994. 43084 is one of the eight HST power cars fitted with buffers in 1987 in connection with DVT trials on the East Coast Main Line. It is a busy moment at Cholsey station in the background, as both the 18:19 Didcot to Paddington and the 17:23 Paddington to Oxford services can just be seen calling at the station.
