A date has been set for the launch of the Night Tube service - almost a year after it was first scheduled to begin.
London Mayor Sadiq Khan said the Central and Victoria lines will start on 19 August, with the Piccadilly, Jubilee and Northern lines following in the autumn.
The service will run through the night on Fridays and Saturdays.
It was due to start last September but was delayed due to disputes with unions.
Last year union members went on strike over the introduction of the all-night service, as well as their pay and conditions.
The service will run:
- Central Line: Between Ealing Broadway and Loughton/Hainault
- Victoria line: The entire line
- Jubilee line: The entire line
- Northern line: Service will not run on the Mill Hill East and Bank branches
- Piccadilly line: Trains will run between Cockfosters and Heathrow Terminal 5
