45678 De Robeck, Hest Bank, 26 June 1949. Single line working during track work, and the Jubilee heads north on the up main. New flat bottom rail has been laid on the down main, and a connection from the Bare Lane line has been severed in front of the loco. What was the purpose of the ground signal at bottom right?
