| Live News reporter Published July 30, 2026 3:00pm Updated July 30, 2026 3:00pm After a rare weekend without any disruption, delays are back on the London Underground (Picture: Getty Images) Londoners are being urged to check before they travel this weekend as an entire Tube line is set to be shut for engineering works. The Piccadilly line faces major disruption on both Saturday and Sunday, with certain sections of the route completely closed as Transport for London carries out planned upgrades. The biggest change will see no Piccadilly line trains running between Cockfosters and Heathrow from around 4am until the end of the service on August 1 and August 2. A reduced service is expected to continue to operate between Acton Town and Uxbridge, however. There will also be a complete closure of the entire Piccadilly line overnight between 12.30am and 4.30am on the weekend. The closures come after a rare weekend without any major planned disruption across the TfL network.

Meanwhile, Finsbury Park station will remain closed throughout the weekend. Anyone travelling across the capital is being urged to allow extra time for their journeys. Earlier this week, TfL was accused of ‘sheer incompetence’ after the scale of fare dodging was revealed. In one year, the practice cost the network £165million – practically wiping out the £168million in extra revenue raised from fare rises on buses and Tubes. Latest London news Ameer Kotecha, from the Centre for Government Reform, which released the figures, said passengers were told the price rise was necessary to improve the network.
