The Tube carries more than a billion passengers each year, with nearly five million journeys each day. To help us meet increasing demand, we are investing into boosting capacity across the Tube network.

The Four Lines Modernisation programme is a £5.4 billion project to modernise the trains, track and signalling on the oldest parts of the Underground – the Circle, District, Hammersmith & City and Metropolitan lines. This work will improve journeys on 40 per cent of the Tube network, and is the largest single upgrade in the history of the Underground. It will result in greater capacity and improved frequency, as well as improved journey times, better reliability and better customer information. Customers have already seen the benefits of brand new walk-through air conditioned trains on this part of the network.

We also plan to replace trains and signaling systems across the four 'Deep Tube' lines - the Piccadilly, Bakerloo, Central and Waterloo & City lines. Our major improvement programme includes new trains for these lines with more capacity and a faster, more frequent service. These trains will also feature air conditioning with walk-through carriages helping to ease extra demand at peak times as well as improved accessibility with step-free access at platform level.

The Central line fleet is undergoing a programme of improvement to ensure that the line can operate with the best possible service until the new trains are introduced. The Central Line Improvement Programme (CLIP) will see motors replaced, accessibility improved and CCTV installed on Central line trains. This will improve reliability and the journeys of thousands of people every day. The project will see trains removed from service, with a new timetable in operation, and will be complete in 2023.
With the projects outlined above, around two-thirds of our lines are being or have been upgraded. We also have a programme of work underway to increase frequencies on upgraded lines even further with new, improved timetables.

Please see the attached requested information, which also references our Renewals and Enhancements Programme to improve stations and introduce step-free access. Further details of these improvements can be viewed via the following link to our website at:
