There have been persistent delays on the line since November 2023 after trains with faulty motors were taken out of service.
This meant a reduced service and crowded trains for passengers, with an interim timetable introduced while repair work was carried out.
Transport for London (TfL) has now confirmed that it will finally be restoring the line’s previous weekday timetable from Monday (January 27).
During morning and evening peak times, there will be between 25 and 28 trains per hour on the core route between White City and Leytonstone. Currently, only 21 trains run at these times.
Matthew Hancox, head of customer operations for the Central line, said: “This uplift has been possible because the repair work on the motors continues to progress thanks to the hard work of our teams, who have been working tirelessly with suppliers to return faulty trains back to service as quickly as possible.
“I’d like to thank Central line customers for their understanding while this work has been going on.”
He added that customers using the line between North Acton and Northolt as well as between Leytonstone and Loughton should also see more trains.
The Ealing Broadway branch is expected to have greater frequency compared to current service levels too.
Despite the uplift, the number of trains available still remains lower than is necessary to run a full timetable.
As a result, the reduced weekend timetable will remain unchanged.
TfL has said it continues to carry out repair work on Central line trains and will “monitor and review when further improvements can be made to the timetable”.
It comes amid progress to upgrade the whole fleet that runs along the line, with a second refurbished train having recently entered service.
This £500 million project is unrelated to the increase in Central line services, but will see trains fitted with new lighting, seating and CCTV.
An increased timetable will also be restored on the Waterloo & City line, providing 21 trains an hour compared to the current service of 18.
