Trains from Battersea Power Station run via Charing Cross only, as the branch extends off the Kennington loop.

Overrun tunnels underneath Battersea Dogs & Cats Home were proposed;[10] however, these were omitted to save money.

[23] The station was given final approval by the Secretary of State for Transport in November 2014,[24] before construction began in 2015, with completion originally scheduled for 2020.

[28]In December 2018, the Mayor of London, Sadiq Khan, announced that the project would be delayed until September 2021 at the earliest "to increase the station's capacity to cope with a higher number of passengers than originally forecast".

[29] By June 2019, major tunnelling and track works had been completed, with an engineering train running on the extension for the first time.

[34] Battersea Power Station noted that demand will increase further as the site reopened as an office and retail complex in October 2022.
