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 until well into 2027, but a fairly major one will be affecting the capital city next week. From Wednesday, October 28 to Friday, October 30, there will be no services running between Cockfosters to Uxbridge – which is pretty much the entire line aside from the branch that heads out to Heathrow Airport.
Next weekend, however, the entire line will be out of action – including services to Heathrow. Next weekend is, of course, Halloween weekend. So, it’s certainly worth keeping these closures in mind when making your plans, as there’s truly nothing spookier than being stranded in full fancy dress. There will be no services at all from Friday night (October 30) until the end of Sunday (November 1). If you need to get to Heathrow Airport during that period, you can hop on the Elizabeth Line or a Heathrow Express service.

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 confirmed closures are as follows:

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.
