Transport for London (TfL) have finally unveiled a map showing the stations and lines that will be in use once the Tube goes 24-hour on 12 September this year.
TfL say they have implemented this round-the-clock service to "support London's 24-hour lifestyle".
The service won't be running seven days a week, instead trains on selected lines will run on Friday and Saturdays throughout the night.
The lines that have been chosen are the Jubilee, Victoria, and sections of the Central, Northern and Piccadilly.
Trains will be running on average every 10 to 20 minutes on most lines and will run throughout the night.
Standard off-peak fares will be in operation during these times.
24 hour tube services:
Jubilee and Victoria lines - trains will run across the entire lines
Central line - trains will run between Ealing Broadway and Loughton/Hainault
Northern line - trains will run between Morden and High Barnet/Edgware
Piccadilly line - trains will run between Cockfosters and Heathrow Terminal 5
TfL say: "The Night Tube will cut night-time journeys by an average of 20 minutes, with some cut by more than an hour. It will also play a vital role in opening up London's night-time economy, supporting almost 2,000 permanent jobs and boosting the economy by £360m."
However the new plans for a 24-hour service have not pleased everyone as Tube drivers have voted to strike over its introduction as well as their pay.
According to the Evening Standard, Aslef union members backed industrial action by 97 per cent last week. The workers will go on strike from 9.30pm on July 8.
