The impressively large Corby gates signal box is the first

block box out of Carlisle on the route to Newcastle. Built by British Railways in 1955 it is a non-standard design replacing a previous structure across the River Eden to the west in Wetherall. The box has been extended witnessed by the different shades of bricks in the base. As well as controlling the semaphores it also operates the level crossing that is unusual in that it has no audible or visual warnings relying solely on the observation of the signalman. Notice the historical George V postbox incorporated into the base.
