B571 Sapperton Tunnel (Mid Point) 2 June 1979

A glimpse of B571 (51052, 59282 & 51080), as it briefly emerges into the light at the small gap between the two Sapperton Tunnels on 2 June 1979. It is working the 2B25 15:30 Cheltenham to Swindon service. Although obviously not noticeable from this view, this set had a Class 120 centre coach.
