London's new night Tube service could be rolled out line by line from this August, it's being reported.
According to the Press Association, Transport for London has not officially named dates for the delayed service to finally start, but it is understood that plans have been drawn up to introduce it line by line in the summer.
Passengers will be able to travel through the night on Fridays and Saturdays on the Victoria and Jubilee Lines from August 5 and then on the Central, Northern and Piccadilly Lines from September 23, it is believed.
The breakthrough comes after a pay deal was accepted by members of the two biggest Tube unions - Aslef and the Rail, Maritime and Transport union.
The Transport Salaried Staffs Association and Unite have yet to accept the offer, but it is understood that TfL is pressing ahead with starting the night Tube in August.
Part-time Tube drivers are currently being trained to deliver the new service, and are expected to be ready for duty by the summer.
The night Tube was originally slated to start on five lines at weekends last September.
