There were some serious delays this afternoon but I can only assume the issues (and pilot man) are because Bromley Cross an loop are effectively disconnected while the signalling work goes on at Bolton. Bromley Cross was left as a fringe box for a long time between Piccadilly an Preston power boxes, how ever it now only controls a foot crossing at the station when the systems were made to talk to each other. I would imagine the pilot man rides into what has effectively become a long siding temporarily from Hall ith Wood to Bolton station.
