Londoners will be able to take advantage of a round-the-clock Tube service on five lines come 12 September.
The Jubilee, Victoria and most of the Central, Northern and Piccadilly lines will host a 24-hour service with trains running on average every 10 minutes or less.
The Night Tube will run on Friday nights and during the early hours of Saturday and Sunday mornings.

Approximately 2,000 jobs will be supported by the Night Tube and Transport for London (Tfl) estimates the service will boost the capital’s economy by £360m.
It also believes the scheme will reduce the demand for illegal, sometimes dangerous minicabs and improve accessibility to Heathrow Airport for passengers flying before 7am at the weekends.
Night services are expected to extend to the London Overground by 2017 and to the Docklands Light Railway by 2021. Night Tube services will also be expanded to the Metropolitan, Circle, District, and Hammersmith and City lines once modernisation programmes are complete.
A Tfl spokesman said: "This would all contribute towards a more vibrant night-time economy in London, with a greater range of uses and a wider demographic, and help to retain London's attractiveness to visitors, residents and businesses."
