Transport for London (TfL) first unveiled plans for a 24-hour Tube service in September 2014 – the bright idea of then-Mayor of London Boris Johnson.
But the service has been delayed by a year, due to conflicts over pay and conditions with the RMT Union.
TFL has confirmed that there will be "an enhanced policing presence during the overnight services", with more than 100 police officers being deployed to patrol the 144 stations that will be open throughout the night each weekend.
Ready to get going? Here’s everything we know so far.
Which lines are included in the launch?
The first lines to open will be the Victoria and Central lines, with the Victoria Line running through the entire route while the Central line trains will run between Ealing Broadway and Loughton / Hainault
Central Line trains are expected to run every 10 minutes between White City and Leytonstone, and approximately every 20 minutes between Ealing Broadway and White City, and Leytonstone and Loughton/ Hainault.
There will be no Night Tube services between North Acton and West Ruislip, Loughton and Epping, or Woodford and Hainault.
Meanwhile, the Victoria Line will run every 10 minutes.
Other lines to be added later in the Autumn include:
- Jubilee line: trains will run on the entire line.
- Northern line: trains will run on the entire line except on the Mill Hill East and Bank branches.
“We also plan to expand the night time service to parts of the Metropolitan, Circle, District, and Hammersmith & City lines once our modernisation programmes are complete” TfL has said.
