31181 South Moreton 12 September 1985

31181 passes South Moreton on 12 September 1985 with a complete rake of refurbished Mk 3 HST coaches, en-route from BREL Derby Litchurch Lane to Old Oak Common. Surprisingly routed along the main line, the 31 was struggling to regain speed, after weaving across from the relief line near Didcot.
