50008 Thunderer & 50015 Valiant have just emerged from Box Tunnel on 19 October 1991, and are about to enter Middlehill Tunnel with the Pathfinder Tours 1Z16 07:58 Paddington to Cardiff 'Hoover Hoop' railtour. I was surprised at the number of people on the road bridge at Box, as clearly the picture of the train exiting the tunnel would be completely ruined by shadows!
