Signalling and Testing on the Elizabeth line

Our plan to complete the outstanding works and bring Elizabeth line into passenger service continues to make progress but we are in the most challenging phase of the project, with software development and systems integration to be completed.

The Elizabeth line will increase central London's rail capacity by ten per cent and will carry more than 200 million passengers per year. It also represents 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 new build central section, and the east and west surface sections.
