Please see below for an email from TfL, setting out details of track renewals they will be carrying out on parts of the District and Circle line between 04 and 12 August 2021.
The track renewals are required to deliver the increased frequency and reduced journey times of the Four Lines Modernisation Programme (4LM), alongside the new signalling also being installed. Once complete, the 4LM programme will improve journey times, frequency and reliability across the four lines. It will allow us to run up to 32 trains per hour and carry up to a third more customers.
The complexity of the planned works means they cannot be undertaken as part of weekend closures. Therefore, between 04 and 12 August 2021:
- There will no service between Edgware Road and Aldgate (via Victoria) on the Circle line, and there will be no service on the District line between Earl’s Court and Aldgate East, for the duration of the works
- The following stations will be closed during the nine-day closure: South Kensington, Sloane Square, St James’s Park, Embankment, Temple, Mansion House, Tower Hill
- There will be a National Rail service only at Blackfriars and Cannon Street
- South Kensington will be completely closed throughout the nine-day closure due to the Piccadilly line currently non-stopping to facilitate the renewal of the escalators (this work started on 27 February 2021 and is planned to last for 13 months)
- Frequent bus services run between South Kensington and nearby Knightsbridge station on routes 14, 74, 414 and C1
- During the weekend, of 7 and 8 August, the District line will also be closed between Earl’s Court and Wimbledon, Kensington Olympia and Hammersmith for track renewal works
A comprehensive customer communications and travel demand management campaign will focus on re-routing, re-timing, re-moding and encouraging customers to use available active travel options such as walking and cycling. We will inform customers via a range of methods, including emails, posters and PA messages at stations, and roll out targeted communications to manage the busiest alternative routes.
We are also developing a package of mitigation measures at key locations – including the use of additional staff - to minimise any customer disruption.
