World's biggest signalling project

This article outlines the work required in resignalling more than half the underground railway system in London, UK. In one area, the company is installing a radio-based Automatic Train Protection system with Automatic Train Operation (ATO), using fixed blocks and a distance-to-go system. The train systems know where the train is through transponders and odometry, and can work out how fast it can safely move. In another part of the network, different ATO is being installed using a transmission-based moving block system but retaining cab-based train operators. This works with inductive loop cables which transmit information to an antenna under the train. A test track facility has been constructed and the first stage of testing has been completed. Both systems have the advantages of increased capacity and the ability to overlay the new system on the old. On the Jubilee Line the upgrade project will include the addition of an extra car to all trains.
