The Bakerloo line will be one of the last lines to be upgraded, but you can look forward to changes like faster journeys and a more reliable service as part of our improvement plan.
Right now, we're working on some other lines, and once we've done that we'll be able to move onto the Bakerloo line. In the meantime, we may need to close parts of the line occasionally, to keep the track and tunnels in good condition.
Also, as some of the tracks are looked after by Network Rail, they may ask us to close it for the same reasons.
We'd love to start work sooner, but with 11 lines to improve, we need to plan it so we keep disruptions to a minimum. In other words, we can't do it all at once.
Once we do start, you'll begin to notice some changes that'll make your journey more pleasant. There'll be new, more comfortable trains, with passenger information and security features to help you during your journey.
Lift replacement at Edgware Road
As part of our plan the lifts at Edgware Road are being replaced with more modern and reliable equipment. Both lifts must be replaced at the same time, which requires a full station closure.
Station closure: Saturday 25 May to late December 2013 inclusive.
We'll also be working on a new signalling system and control centre which will help make travelling on the line faster and more reliable. Average journey times will be reduced by more than two minutes and your trains will run more regularly.
And more frequent trains means more capacity - or room - on the line. That's good news, because as London keeps growing, there'll be more people using the Tube.
Paddington station (Hammersmith & City)
More than 60,000 passengers currently use the Hammersmith & City station every day and demand has already increased dramatically as a result of the extension of the Circle line to Hammersmith.
We need to prepare for further increases in demand in advance of Crossrail services in 2018.
