Building the last Main Line Railway
Catesby Tunnel and Viaduct: gcrcs182
View of the timber head gear and winding cable employed
during the sinking of Pit Shaft No 7. Catesby Tunnel in Northamptonshire was
the largest tunnel on the London Extension, and required several shafts to be
sunk in order to excavate it fully. The pole with steps leading to the 'Y' at
the top was installed as a safety feature because it supported the winding rope
and prevented it from being tangled on the ground when slack. The head gear is
partially screened by wooden planking, while in front of it stands several
mineral and tipping wagons. The wagon on the right is lettered 'T O & Son'
indicating its owner as being Thomas Oliver - the contractor responsible for
this section of the line.
