Twizell a Half Century Ago

Twizell was at Marley Hill during the 1970s.   The photo shows removal of tanks in those early days.   Derek Knott is on the bunker & Peter operates the Smith Rodley steam crane (which is now at Beamish).   I'm unsure of the others, does anyone know?

Twizell's water tanks were renewed at Beamish.   Note the very open aspect.   I think the overhead wires in the foreground are shed telephone, in the distant background is the high voltage feed to Marley Hill Colliery
