' A North Eastern Railway gantry signal box. A similar one at Hexham is a listed building. Probably built in the 1870s, after the requirement for the interlocking of railway points and signals came into place. These gantry boxes gave excellent sighting of trains under the signalman's control, but also provided a solution to adding boxes to an established system, where space was limited. '
