The latest modelling suggests that annual passenger journeys on the extension are expected to continue increasing and may reach up to 10 million trips per year in 2024/25.

The new Tube stations at Battersea and Nine Elms see 80,000 and 40,000 trips each week respectively.

Battersea Power Station is the busier of the two new stations with approximately 80,000 trips per week and almost 15,000 trips routinely recorded on the busiest day of the week (Wednesday). Nine Elms station attracts more than 40,000 trips each week and almost 8,000 trips on the busiest day. In June, TfL doubled the frequency of trains on the extension, from six to 12 trains per hour during peak times, and from five to 10 trains per hour at off-peak times.  

Key destinations for trips made from the new stations at Battersea and Nine Elms include Bank, London Bridge, Leicester Square and Waterloo. Analysis of journey times before and after the opening of the extension found it has led to an average 17-minute reduction in passenger journey times between the area and the City and West End, representing a decrease of almost 50 per cent.  

Andy Lord, TfL's Chief Operating Officer, said: "We opened our new Northern line stations with great pride and excitement a year ago and it has been fantastic to see how quickly they have become part of the fabric of the city as people have returned in increasing numbers to the Tube network following the pandemic. Since June, we've doubled the number of trains serving the extension to give our customers a more frequent service to align with growing demand. Transport plays a critical role in opening up jobs, housing and leisure across the city, with these two new Tube stations clearly demonstrating how faster transport links help neighbourhoods develop and thrive."
