The Elizabeth line will connect 41 stations, across over 100km of track, 42km of which is new and in tunnels under London. When fully open, the new railway will increase central London's rail capacity by ten per cent and will enable more than 200 million passenger journeys per year. It is also the first-time national rail lines to the east and west of London have been connected through an underground metro system.
The Elizabeth line consists of three sections - the newly built central section, and the east and west surface sections. Part of the complexity of the Elizabeth line, and the reason that testing and systems integration is a very important part of the process, is that each of the three sections has a different signalling system. All three signalling systems need to successfully work together, including smoothly transitioning from one to another whilst trains are moving across London.
