Over the next two days more than 700m of track is being replaced at Turnham Green and engineers will also renew a set of signalling points at Acton Town.
As a result there will be no service on the Piccadilly line between Hammersmith and Northfields / Uxbridge and no service on the District line between West Kensington and Ealing Broadway / Richmond this weekend.
TfL says customers travelling to Heathrow from central London should go to Ealing Broadway Tube station, via the Central line, and board the express replacement bus which will take them to Boston Manor where they’ll be able to join the Piccadilly line and continue their journey.
To travel into central London from Heathrow, customers can get the Piccadilly line to Boston Manor and change for the rail replacement bus to Ealing Broadway for the Central line.
Piccadilly line trains through central London will run at reduced frequency and will be very busy and passengers are advised to use alternative Tube routes where possible.
Additionally, for travel to and from west London customers should use Circle line services between King’s Cross St. Pancras and Hammersmith.
TfL is promising trains will be able to run faster and more smoothly through the area while points failures will be much less frequent following the work.
David Waboso, LU’s Director of Capital Programmes, said: “Our engineers will be working around the clock this weekend to carry out this vital improvement work.
“I am sorry for the disruption to customers during the closure, which we are keeping as short as possible.
“When the work is completed by the early hours of Monday morning, the track will be immediately more reliable and trains will be able to travel faster through the area.”
