Piccadilly Line Faces Weekend Closure for Train Upgrades
HNL visual fileLondon

Passengers using the Piccadilly line face another three-day closure from August 25 to August 27. Transport for London (TfL) has announced that the section of the line between Cockfosters and Uxbridge will be suspended to allow for essential upgrade works. This disruption is part of a larger programme to prepare the route for a new fleet of trains.

During the closure, there will be no service on the Piccadilly line between Cockfosters in the north and Uxbridge in the west. However, the line will continue to operate between Acton Town and Heathrow Airport, serving passengers travelling to and from the airport.

Track work and repairs will disrupt services across central and south London.

Replacement Services and Alternative Routes

To assist passengers, TfL will be running replacement bus services. These include the PL4, which will operate between Acton Town and Rayners Lane; the PL5, running between Finchley Central and Cockfosters; and the PL6, connecting Finsbury Park with Arnos Grove. TfL advises all travellers to check their journey plans using the TfL journey planner before travelling.

Alternative Tube lines have also been suggested for those affected. The Metropolitan line between Rayners Lane and Uxbridge, and the District line between South Kensington and Ealing Common, may offer suitable routes. Passengers are strongly encouraged to plan ahead and allow extra time for their journeys.

Signalling issues and a fire alert cause widespread disruption across multiple Tube lines on Tuesday morning.

New Trains and Capacity Increase

The current closures are a necessary step in the Piccadilly Line Upgrade project, which aims to replace the line's ageing 1970s trains with 94 new ones. These new trains are scheduled to enter passenger service between December 2026 and June 2027. They will feature modern amenities such as air-conditioning, walk-through carriages, and digital information displays.

Once the new fleet is fully operational, TfL anticipates a significant increase in peak capacity through central London. The number of trains running per hour is expected to rise from 24 to 27, leading to a projected 23 per cent increase in peak capacity compared to the current service. Each new train will also offer approximately 10 per cent more passenger capacity.

The wider upgrade programme includes track and power system improvements, as well as enhancements to maintenance facilities at Cockfosters and Northfields. Further planned closures for the Piccadilly line are scheduled for September, October, and November as this extensive upgrade work continues.
