TfL estimate the line will be used by 200 million passenghers each year and increase rail capacity in the capital by 10 per cent.
Mayor of London Sadiq Khan said: ‘It’s truly exciting that in only a year London will see the opening of one of the biggest new transport projects in a generation.
‘The new map being unveiled shows how the first phase of the Elizabeth line will connect to key parts of the transport network in the heart of central London, substantially reducing congestion on other key Tube lines as London’s population grows.’
All new trains will have a walk-through feature and be fully air conditioned, with live information and free WiFi. All 41 stations on the line will be step-free from street to platform. Ten new stations have been built to serve the new line, while the other 31 have been refurbished.
Rail minister Paul Maynard said: ‘Seeing the Elizabeth line on the Tube map for the very first time is exciting confirmation that we are closer than ever to delivering a transformative change in London’s rail network.
‘That means better, faster journeys for over half a million passengers per day, as well as offering new connections that will link people to Heathrow, Gatwick and Luton.’
