<a href="//commons.wikimedia.org/wiki/Beamish_Museum" title="Beamish Museum">Beamish Museum</a>, County Durham, England. This is wagon No. BSC 66, seen here inside the Beamish Engine Works on the <a href="//commons.wikimedia.org/wiki/Beamish_Museum:_Colliery" title="Beamish Museum: Colliery">Colliery</a> railway, looking towards the door in the front. It's a former Great Western Railway Macaw B bogie bolster (flat wagon), later converted to a well wagon, as seen here. It has since been further modified by Beamish with the addition of I-beams across the top of the well, to return it to a type of flat wagon, for use as a carrier for an ice rink chiller unit.
