The good news: brand new Piccadilly line trains are incoming. The bad news: that means a series of planned closures on the line for the rest of this year.
Ahead of the fleet of 94 new Siemens Mobility trains taking to the Piccadilly line sometime in 2025, track, points and crossings in the Arnos Grove area have to be renewed, and work carried out around Cockfosters station, Cockfosters Depot and the Arnos Grove train sidings. The new trains will also begin test runs on the line later in 2024, all of which will cause long-running disruption.
That includes:
- Sat 20-Sun 21 July: Line closed King's Cross St Pancras to Heathrow and Rayners Lane
- Sat 27-Sun 28 July: Line closed King's Cross St Pancras to Cockfosters
- Sat 3-Sun 4 August: Line closed King's Cross St Pancras to Cockfosters
- Sat 17 August-Sun 1 September: Line closed Wood Green to Cockfosters, and Rayners Lane to Uxbridge. Replacement bus services will run, though if you're travelling to central London, it may be faster to catch a local bus to an operating tube station and make your way from there.
- Sat 14-Sun 15 September: Line closed King's Cross St Pancras to Northfields and Rayners Lane
- Sat 21-Sun 22 September: Line closed Acton Town to Uxbridge
- Sat 19-Sun 20 October: Line closed Acton Town to Rayners Lane
- Sat 23-Sun 24 November: Line closed King's Cross St Pancras to Hammersmith
- Sat 30 Nov-Sun 1 December: Line closed King's Cross St Pancras to Cockfosters
- Sat 7-Sun 8 December: Line closed Acton Town to Rayners Lane
TfL recommends planning ahead and allowing more time for your journey on the above dates. As far as we can tell, the only replacement bus service will be on that two-week closure stint between 17 August and 1 September. Though not confirmed, we'd imagine disruption will continue into early 2025 — ahead of the new trains' arrival. It'll be worth all the hassle, we're sure.
