Piccadilly line closures: check your Heathrow journey before the Halloween weekend

29th October 2026

A familiar blue line on the Tube map will need a second look this week. Transport for London lists a major Piccadilly line closure for Thursday 29 and Friday 30 October, followed by a full-line shutdown over the weekend. If you are heading to the airport, meeting friends or returning from a late event, check the date and time of both parts of your trip before leaving home.

The practical point is that the Thursday arrangement and the weekend arrangement are different. A route that works today may no longer be available for the journey back. Build your plan around the actual departure time, especially if an evening out runs beyond midnight.

What is closed, and when?

TfL’s planned-works timetable lists no Piccadilly service between Cockfosters and Uxbridge from Wednesday 28 to Friday 30 October. Its live notice says trains continue between Acton Town and Heathrow, serving all terminals. For the following period, from Friday 30 October’s Night Tube through Sunday 1 November, the upgrade page lists no service anywhere on the Piccadilly line.

The transport authority says the programme combines preparations for new trains with routine maintenance. It warns that some closures extend into weekdays and that work can also affect other lines. These dates are the published plan, so make a fresh check before travelling rather than treating a saved screenshot as a live service guarantee.

Heathrow passengers: plan from your front door

For the current weekday disruption, TfL directs travellers between central London and Heathrow towards the Elizabeth line. It also identifies the Metropolitan line as an alternative between Rayners Lane and Uxbridge. Replacement buses are listed for affected areas, including links towards Acton Town, Finchley Central and Finsbury Park.

Do not assume that reaching a replacement-bus stop gives you the same arrival time as the usual train. Allow for the walk to the stop, waiting and the onward interchange. For a flight, work backwards from the airport arrival time recommended by your airline and leave a margin for an unfamiliar connection. Check the terminal printed on your booking before selecting your destination.

For a group, agree the revised meeting point in advance. A message saying “the usual station” is easy to misunderstand when different entrances or services are affected. Share the intended route and a sensible fallback, particularly if somebody is travelling with children or bulky bags.

Choose a route that you can actually use

TfL’s accessibility guidance explains that Journey Planner and TfL Go can compare journeys with fewer changes or less walking, as well as the fastest route. Options cover stairs, escalators and transport preferences. This is particularly useful when disruption turns a direct journey into several separate stages.

The authority also publishes accessibility maps, including a step-free Tube guide, and provides information for individual stations, stops and piers. Consult those details for every interchange you intend to use. A familiar destination does not make an unfamiliar connection suitable for everybody.

On the move, check station information boards and announcements and ask staff if the route is unclear. If you need a particular lift, treat its operating status as part of the journey check. Give yourself enough time to change the plan without being forced into a connection that does not meet your needs.

Make the return journey part of the plan

Before a gig, dinner or Halloween event, decide how you will get home at the expected finishing time. Check whether your outward route crosses into a different closure period on the return. Keep your phone charged and save the venue address as well as the name of the station you hope to use.

These checks need only take a few minutes, but they are more useful before you leave than on a platform with a deadline approaching.
