The changes to London Underground running times take effect from 19 August.
Yet, the Hillingdon area is missing out, with no trains running as far as the borough during the new night hours at all, on either the Central Line, Metropolitan or Picadilly.
The nearest station to Hillingdon where night tubes are set to run is Ealing Broadway on the Central Line. The trains will run to the end of the line on the east side of London, however, to Hainult and Loughton.

Asked by Hillingdon is Here when commuters from this part of west London might be able to benefit from the all night tube, Transport for London said an extension of the service may be considered, but only once upgrades to the Met line are completed in 2023.
The London Mayor's office is yet to respond to questions submitted last week.
Hillingdon is Here asked TfL and The London Mayor's office why West London hasn't been included in the initial roll out.
We also asked if there were plans to extend the night tube out to stations such as West Ruislip, Uxbridge, Hillingdon, Eastcote, Ruislip and Ickenham and if not, why.
TfL provided a statement, which read: “When the initial night Tube network is up and running, we’ll keep it under review and would hope to extend it in future.
“On the Circle, District, Hammersmith & City and Metropolitan lines there is a major modernisation programme underway which will continue to require a higher level of overnight engineering work.
“Once the modernisation work on the Circle, District, Hammersmith & City and Metropolitan lines is complete in 2023 we will look at introducing night Tube on the parts of those lines where there is a demand.”
The Mayor's office has not provided responses to the questions.
Asked whether there would be any additional night bus services running to West London locations where the night tube is unavailable, TfL stated: “No decisions will be taken until new bus ridership levels have settled down after the night Tube has opened.”
The Night Tube will operate on Fridays and Saturday nights from:
Central line: between Ealing Broadway and Loughton/Hainault
Victoria line: entire line
Jubilee line: entire line
Northern line: entire line except on the Mill Hill East and Bank branches
Piccadilly line: between Cockfosters and Heathrow Terminal 5Central and Victoria lines to go live first, with Piccadilly, Jubilee and Northern to follow in the autumn

The first 24-hour weekend Tube travel in the capital's history starts on the Central and Victoria lines on 19 August.
There will be six trains an hour through central London on all night Tube lines between 12.30am and 5.30am.
The Jubilee, Northern and Piccadilly lines will follow in two separate phases later in the autumn as new Tube drivers complete their training and final preparations are made, the Mayor's office said.
Officials claimed that the all hours Tube will support around 2,000 permanent jobs and boost London's night-time economy by £360m.
The Mayor of London, Sadiq Khan, said: "The Night Tube is absolutely vital to my plans to support and grow London's night time economy - creating more jobs and opportunities for all Londoners. The constant delays under the previous Mayor let Londoners down badly.”
London’s Transport Commissioner, Mike Brown, said: “It is good news for London that the first ever all-night Tube service will be ready on 19 August. More than half a million people use the Tube after 10pm on Fridays and Saturdays, and the introduction of the Night Tube, which will support London's businesses and jobs, is a historic step in our modernisation of the Underground and our work to support London’s economic growth."
