Transport for London (TfL) has confirmed severe disruption for passengers heading to Heathrow Airport on the first weekend of August. Trains will not run between the airport and Cockfosters on both Saturday and Sunday due to ongoing upgrade works on the Piccadilly line. The Night Tube on Friday and Saturday is also suspended for the same reason. Rail replacement buses will operate, TfL said.
Piccadilly line closures
On Friday, July 31, there is no service between Cockfosters and Uxbridge due to line upgrades. The entire line is closed during Friday Night Tube. On Saturday, August 1, and Sunday, August 2, no service runs from Cockfosters to Heathrow Airport, including during Saturday Night Tube. Until late 2026, westbound trains will not stop at Barons Court due to staircase and canopy improvement work.
Overground line closures
Network Rail maintenance work will shut sections of the Lioness, Mildmay, and Windrush lines on Sunday, August 2. On the Lioness line, no service runs from Euston to Kilburn High Road until 12pm and after 8.30pm. On the Mildmay line, no service runs from Camden Road to Stratford after 10.15pm. On the Windrush line, no service runs from Wandsworth Road to Clapham Junction; trains will call at Battersea Park instead.
District line and DLR
Until late 2026, westbound District line trains will not stop at Barons Court due to improvement work. On Sunday, August 2, there is no DLR service from Tower Gateway to Shadwell due to third party works.
Charing Cross and Waterloo East closures
Charing Cross and Waterloo East stations remain closed until mid-August for major track renewal. Engineers are replacing 1,800 metres of aging track, rebuilding platform foundations and surfaces, improving drainage, and completing repairs on the Hungerford Bridge. Southeastern trains are being rerouted to Victoria, Cannon Street, and Blackfriars, with other services terminating at London Bridge.
