EWS 66139 unusually doubleheads 66199 past Witham Friary working 3S13 Westbury-St Blazey Rail Head Treatment Train on Wednesday 23rd November. 66199 suffered a AWS fault in No. 1 cab hence the doubleheading. 66199 was turned later at St Blazey so No. 2 cab was on the outside so the train could work 'top and tail' for its next working (3S11).
