Here's something you don't see everyday - Class 60 clag! The driver of 60059 Swinden Dalesman applies the power as he passes Wolvercote on 22 July 2012 with the 6E38 17:03 Colnbrook to Lindsey Oil Refinery aviation fuel empties. Luckily this was running exactly to time, as the foreground shadows were advancing rapidly across the line.
