North Weald station, with its original concrete footbridge, pictured on 22 July 1993, just over a year before the line closed. The conductor rails, and cables crossing the bridge clearly indicate that this was part of the London Underground network, but the rural Essex location is just about as far removed from most people's idea of the underground as it is possible to get. In 1993 trains only operated during the morning and evening peaks. After closure the line became the Epping Ongar heritage railway. Although the station building and signal box survive, unfortunately the footbridge's internal steel reinforcing rods were suffering from serious rust due to water ingress, with the result that bits of concrete were dropping off. The decision was taken to demolish it and replace it with a steel bridge recovered from Churchfields on the Central Line.
