66502 Basford Hall Centenary 2001 moves onto the up relief line at Challow on 21 March 2016 with the 4L31 09:03 Bristol to Felixstowe North freightliner. This is probably my most frequently photographed freight train, principally because it runs at an ideal time for the light, and because since the announcement of the Great Western Mainline electrification scheme, I have taken every opportunity to photograph it before the wires go up and ruin all my favourite Vale of White Horse locations.
