A General Electric “NR” class loco is re-railed after an “argument” with a Dual-guage turnout at the rail welding facility at Clapham yard.What started out as an easy lift, soon turned into a drama ,as the lip on the back face of the centre wheel snagged on the head of a bolt. To make things a bit more interesting ,the wheel had also jammed itself between the Narrow gauge and Standard gauge switch rails!.
