Part-closure will begin on Saturday 10 February and last until Wednesday 14 February
A partial closure will affect Piccadilly line customers from Saturday 10 February until Wednesday 14 February for ‘important engineering work’, Transport for London have announced.
Vital upgrade works to points at Northfields will be completed during the closure, improving the line infrastructure alongside the introduction of ‘transformative’ new trains from 2025. Other important work will also be completed, including infrastructure work at Heathrow Airport stations.
The Piccadilly line will be closed between Hammersmith and Heathrow Airport from 12.45am to 5.00am on Saturday 10 February, meaning there will be no Night Tube west of Hammersmith station. From Sunday until the start of normal service on Thursday 15 February there will be no trains between Acton Town and Heathrow.
The points at Northfields are on a complicated stretch of track where trains come out of Northfields depot to enter service. The track in this area features some components from the 1930s and must be replaced as the assets are unreliable and maintenance is costly.
TfL say the closure will take five days because it is not a like-for-like renewal, which means that once the first section is removed, the rest of the track in the area must be removed and replaced. Replacing the track will not only address the ongoing issues but will also mean a better, smoother ride once the new Piccadilly line trains are introduced.
London Underground customers are encouraged to plan ahead during the works, using real time travel tools such as TfL Go and Journey Planner, to check before travelling and to allow more time for their journeys.
Customers travelling to Heathrow Airport should use Elizabeth line services. There will be rail replacement buses serving local stations from Acton Town to Heathrow Airport, as well as many local buses.

Closure crucial to make way for upgrades to Piccadilly Line due in 2025
The new Piccadilly line trains are part of a £2.9bn investment to modernise the Piccadilly line, rolling out 94 brand new trains from 2025 onwards to help the line run more reliably, safely, inclusively and sustainably.
The new trains will feature walk-through carriages, air-conditioning, wider all-double doorways to help customers get on and off more easily, enhanced digital display screens for customer information, on-train CCTV cameras for additional customer security and will, for the first time on a Deep Tube train, provide air conditioning. They will increase capacity by 10 per cent and will also improve energy efficiency and accessibility.
The points are located beneath a bridge, which means they cannot be replaced quickly during engineering hours. This has meant the need for a closure of the line to carry out the work. With the line closed, infrastructure work will also take place around Hounslow and at stations at Heathrow Airport so that TfL can minimise future disruption.
Richard Jones, Director of Asset Performance Delivery for TfL, said:
“We thank customers in advance for their patience during this vital closure of the Piccadilly line. The track at Northfields has to be replaced and doing so will make journeys smoother and more reliable, as well as enable us to deliver as much of the improvements made by the upgrade to the Piccadilly line as possible.
“The Elizabeth line will help customers reach Heathrow Airport during this closure but we will also be operating rail replacement buses in Hounslow and the surrounding areas. Customers should check before they travel and leave more time for their journeys during this work.”
