We're planning a major project that will bring the Piccadilly line up to date and include new trains and faster, more reliable journeys.
One signalling system and train fleet - with walk-through, air-cooled carriages - will operate on all our deep Tube lines. These will be introduced first on the Piccadilly line from the early 2020s and, following this, on the Bakerloo, Central and Waterloo & City lines.
The new signalling and trains will mean around 60% extra capacity - or room - on the Piccadilly line at the busiest times. This is space for more than 20,000 more customers an hour.
We may need to close parts of the line from time to time to keep track and tunnels in good condition.
A major project is planned at Finsbury Park station to reduce congestion and speed up journeys through the station, provide step-free access and a new station entrance.
These improvements are set to be complete in 2019. The works are being coordinated with a major new private redevelopment adjacent to the station to minimise disruption.
The staircases from the Tube to National Rail platforms will be closed to the public until the end of March 2014. Works on these staircases will double their capapcity.
Green Park station has been renovated. The station now has step-free access to all platforms, and between all lines. Platform humps provide level access to trains.
Above ground, the new, ramped station entrance provides direct access from Green Park.
Heathrow Terminals 1,2,3 station
Extensive improvements to Heathrow Terminals 1,2,3 station, made in cooperation with BAA, are now complete.
New lifts to platforms provide step-free access and platform 'humps' now offer level-access when boarding trains.
The upgrade also includes a modernised ticket office, additional gates, new signage and Help Points.
This vital interchange between the Piccadilly and Central lines is already experiencing very high demand. We have a plan to increase capacity and ensure that the station can fully support the benefits of the Piccadilly line modernisation.
By 2022, a new interchange link and a re-modelled ticket hall will reduce journey times, boost capacity and make the station step-free.
We are completely refurbishing the three lifts at Russell Square station, one at a time, to improve their reliability. While this work takes place, queues to enter and exit the station are likely, especially at busy times.
You can avoid queuing by using Holborn station instead. This is a short walk away and also close to many of the hotels, amenities and attractions in the area.
