It is 05:30 on 14 June 1983, and while most of the residents of nearby Oxford are still asleep, the very first glimmer of sunlight starts to illuminate the scene at Hinksey Yard. 47315 slowly weaves across from the up relief line, over the main running lines, and into the yard. The working is the 7V12 01:53 Toton to Didcot Power Station MGR, which was not booked to do this, so presumably there was some problem with the train, or more likely, with the power station. At the time the Didcot coal trains were mostly in the hands of Class 56s.
