Foxfield Railway - crane tank demonstration. Dubs crane tank No. 4101 of 1901 is lifting some material while "Wimblebury" is moving following a points change. "Wimblebury" is an Austerity saddletank delivered new in 1956 to the National Coal Board at Cannock Wood Colliery and withdrawn in the early 1970s. This is an ideal locomotive for the Foxfield Railway as it is a colliery railway.
