The Piccadilly line will be part-closed for "essential" engineering work during half-term next week, TfL has announced - hampering services to Heathrow.
The closure will take place from Saturday, February 10 to Valentine's Day. The line will be closed between Hammersmith and Heathrow Airport between 12.45am to 5am on Saturday, and between Acton Town and Heathrow from Saturday morning to Thursday, February 15.
However, passengers will still be able to use the Elizabeth line to reach the airport.
It comes as commuters today face disruption due to the last day of the Aslef union's overtime ban, and continued delays on the Central line because of train shortages.
