Piccadilly line trains will resume service at South Kensington station from next week after being closed for 15 months.
The service has been closed since February 2021 while work is carried out to replace five escalators.
South Kensington station remained open for Circle and District line customers for the duration of the works.
Visitors to the Natural History Museum, Science Museum and Victoria and Albert Museum will have easier access to the area from Wednesday June 1, when the Piccadilly line trains will serve South Kensington again.
Esther Sharples, TfL’s director of asset performance and capital delivery, said: “I’d like to thank our customers for their patience while Piccadilly line services have been non-stopping at South Kensington.
“Replacing the nearly 50-year-old escalators with new, high-performing machines will mean more reliable journeys for Piccadilly line customers for decades to come, whether they are using the station as a local resident, for work or to access the area’s world-famous cultural attractions.
“I’m delighted that the Piccadilly line will serve South Kensington again ahead of the Platinum Jubilee celebrations, which will bring more visitors to the area as they seek to enjoy all that this vibrant area of London has to offer.”
Emily Candler, executive director of Exhibition Road cultural group, said: “I am delighted that South Kensington will have a full service again making it easier for people to come to all the exciting events and activities here.
“The Great Exhibition Road Festival returns on June 18-19 and we’re gearing up for a fantastic summer with free activities for all ages, great exhibitions, and unforgettable performances.
“The station being fully open for the first time since the pandemic will make a huge difference to visitors, staff, students and residents and help us to welcome people back to London’s original cultural district.”
