						the steam and smoke from Catesby tunnel. Photographed around 1897, these two
						navvies are dressing the ground after the shaft has been completed. The shafts
						were also used during the construction of the tunnel providing access to drive
						the bores and deliver materials and men. A quite imposing structure in its own
