Generator van clag! The generator van seems to be doing more work than the loco, as 56071 emerges from Dove Holes Tunnel on 8 February 2003 with the Pathfinder Tours 1Z27 04:43 Bristol Temple Meads to Buxton Sidings 'Folly Forester' railtour. 20312 & 20306 are out of sight in the tunnel, on the rear of the train. Unfortunately the dull winter day, and the dark location only allowed an exposure of 1/250sec f1.4, which explains the very poor technical quality.
