A welcome surprise at the end of a warm summer evening at Wolvercote Junction. In the mid 1980s the standard traction on MGR coal trains to Didcot Power Station was Class 58s, with occasional Class 56s. Therefore I was very surprised to see 37147 heading north with MGR empties, just as the sun was setting on 6 July 1987. Presumably this is the 6M61 20:00 Didcot Power Station to Toton. With just the very last glimmers of the sun giving a slight pink tinge to the ballast and the A34 bridge, the light was so low that 1/250 sec was all that was available with the lens wide open on good old grainy Kodachrome 200. Despite this, I wasn't going to miss getting a picture of a 37, complete with original skirts and round buffers, hauling a rake of HAAs.
