There are two new stations on the world famous Tube map.
Together Battersea Power Station and Nine Elms make the first extension to the Northern Line for 80 years.
In this special programme, we speak to Transport Secretary Grant Shapps, Mayor of London Sadiq Khan and others as the first passengers got on-board.
We hear how the £1.1 billion project is seen as the catalyst for the wider redevelopment of the Nine Elms area, with the former power station at its heart.
And we also learn how discussions between TfL and the government are going as the transport network looks for a long-term deal to provide stability after the devastating effects of coronavirus.
