The London Underground’s Piccadilly line will be almost completely shut for two weekends in March

Regular users of London’s Piccadilly line, heads up. The navy blue tube service will be severely disrupted for two weekends over the next month or so, with huge sections of the line completely down from Friday night tube all the way through to late Sunday night.

On March 6-8 and then again on March 20-22, there will be no Piccadilly line trains running between Cockfosters and Uxbridge. That means the entire central London section of the line will be down (with trains only running between Acton and Heathrow on the western end).

TfL says that the closures are so that the Piccadilly can get ready for its long-awaited new trains. The brand-spanking-new carriages, which were revealed back in 2021 and will be walk-through and air-conditioned, were supposed to be introduced in late 2025 but that was delayed to 2026. You can find all the features that the Piccadilly line’s new trains will – and won’t – have here.

The March weekend closures won’t be the only disruption to Piccadilly line services in the coming months. A bunch of other closures have been confirmed for between April and July, though few are quite so severe and long-lasting as the ones in March.

When will the Piccadilly line be closed in March?

These are the dates on which you need to watch out for Piccadilly line closures next month:

• March 6 (night tube only), all day March 7 and 8.
• March 20 (night tube only), all day March 21 and 22

Will the entire Piccadilly line be shut?

Nope, but the bulk of it will be. All stations will be shut between Cockfosters in the north and Uxbridge in the west, though the Acton Town-Heathrow section will stay open.

How to get to Heathrow airport during the Piccadilly line closures

When the Piccadilly is (mostly) down, you’ll still be able to use train routes like the Elizabeth line and Heathrow Express to get to Heathrow. Or you can still use the Picc, though you’ll need to get to Acton Town on the District line.

Of course, you can get to Heathrow by other means, too – like coach, taxi and your own car.
