47583 County of Hertfordshire approaches Bridgefield Bridge near Stonesfield on the Cotswold Line with the 13:35 Paddington to Hereford service on 7 May 1989. Although running more or less on time at this point, this train would have to wait at Ascott-under-Wychwood as engineering work on the double track section between there and Moreton-in-Marsh was overrunning slightly.
