New subway stations at Battersea Power Station and Nine Elms are slated to open in just over two weeks.
The Northern Line expansion worth $ 1.1 billion
Transport for London (TfL) has confirmed that the two new Zone 1 stations will open to the public on Monday 20th September.
Originally the project was supposed to open at the end of last year, but in December 2018 TfL postponed the opening date by nine months.
At the time, TfL said the opening of the new line had been “realigned” to coincide with the opening of the Bank Station expansion, creating more capacity on the line.
But when the pandemic halted construction, the schedule for the Bank train station expansion, which postponed completion for at least the middle of next year, suffered.
Services on the Northern Line extension, which operate from Kennington Station at the Charing Cross branch, will begin with a peak time of six trains per hour and will increase to 12 trains by mid-2022. During off-peak hours, five trains per hour will run, and next year there will be ten trains.
Major construction on the 3 km long double tunnel railway began in 2015, with the joint venture winning the £ 500 million prime contractor the year before.
