London’s pioneering Piccadilly Line will be turning 120 years old later this year. And having been paying its dues for well over a century, the distinguished dark blue line will be marking the monumental milestone with a rather mighty makeover.
A fleet of 94 state-of-the-art-trains are mere moments away from chugging into passenger service. But in preparation for these swanky new vehicles hitting the track, Transport for London has announced that the line will face a number of fairly significant closures over the coming months. And we’re here to clue you up on those closures, so you don’t get caught out.
When will the Piccadilly Line be closed?
There will be closures taking place on the navy blue line later this month. There will be no service between Hammersmith and Heathrow and Uxbridge throughout the weekend of October 17 and 18 (including the Friday night tube). And then two weeks later (October 30 and 31), there will be no service on the entire line. So, bear this in mind when making any Halloween weekend plans, folks.

When are the future Piccadilly Line closures taking place?
Whilst Transport for London prepares for the new-and-improved trains, there will be intermittent closures affecting the Piccadilly Line. The currently-confirmed closures are as follows:
- October 16 (Night Tube) – no service between Hammersmith and Heathrow and Uxbridge
- October 17-18 – no service between Hammersmith and Heathrow and Uxbridge
- October 28-30 – no service between Cockfosters and Uxbridge
- October 30 (Night Tube) – no service on the entire line
- October 31-November 1 – no service on the entire line
- November 20 (Night Tube) – no service between Hammersmith and Heathrow and Uxbridge
- November 21-22 – no service between Hammersmith and Heathrow and Uxbridge
The Piccadilly Line upgrade
Whilst tube line closures are undeniably inconvenient, it’s highly likely that these ones will be worth it. Over £3 billion has been invested into this highly-anticipated upgrade – and Londoners will start to see the nifty new trains enter service between December 2026 and June 2027.
The new trains will boast walk-through carriages, wider doors, enhanced digital displays, and improved step-free access. They’ll also be decked out with air conditioning, thus marking the first time that a deep-level tube line in London will have lovely, cool carriages. During the upcoming closures, upgrade preparation and routine maintenance will be taking place on the track.
As always, keep your eye on the TfL website before you travel, plan ahead, and allow extra time for your journeys.
