With Didcot Power Station dominating the background, 37215 & 37294 pass Milton on 24 October 1989 with the 6B33 10:03 Theale to Robeston Murco oil empties. Both locos are in the same Railfreight Petroleum livery, but it is obvious which one has seen the washer most recently! Both locos at this time were in Cardiff Canton's FPEK petroleum pool, and were frequent performers on this train.
