Londoners are being warned of closures to six Tube lines over the Easter holiday.
There will be no trains on the Hammersmith & City Line and parts of the District Line from Good Friday to Easter Monday to allow the removal of a disused ticket hall at Whitechapel.
Some sections of the Piccadilly Line will also be closed for engineering work.
TfL’s Chief Operating Officer, Andy Lord, said: "Easter is a brilliant time to get out and explore London.
"I’d encourage customers to check before they travel as there are some closures, but the majority of the public transport network will be open over the Easter weekend, meaning people can enjoy everything the capital has to offer.
"We’re seeing more and more people using our network again, which is a great sign, and we’re pleased to welcome them back."
