Overpowered? 70804 passes Bourton on 4 March 2014 with the 6M50 07:55 Westbury to Bescot engineers train. This was the second day of Class 70 operation on this service. Such is this class's poor reliability, that 70804 managed only two days of trouble free running on this working, before failing at Hinksey the day after this picture was taken. Terrible performance for a new loco! Just visible underneath the bridge in the background is a track worker waving his chequered flag as a warning of this train's approach to fellow workers.
