66750 Bristol Panel Signal Box runs alongside the Kennet & Avon Canal near Crofton on 23 August 2016 with the late running 6V42 08:13 Wellingborough to Whatley Quarry stone empties. Until recently Foster Yeoman and ARC (latterly Mendip Rail) had a monopoly of the Somerset stone traffic, now there is this GBRf interloper!
