Bakerloo line an extension of the line to the south-east may be built, including to Camberwell. In this scenario, an extension to the Bakerloo line would no longer be required. However, recent plans are instead to extend this Northern line branch towards Battersea via two new stations at Nine Elms and Battersea Power Station, so that it is once again the Bakerloo line that would provide any extension to Camberwell. In its July 2011 London & South East Route Utilisation Strategy, Network Rail recommended extending the Bakerloo line from Elephant & Castle to Lewisham and then taking over the Hayes Line. This
Charing Cross tube station opened. The constituent stations also underwent a number of name changes during their history. The first part of the complex, the Bakerloo line platforms, was opened as "Trafalgar Square" by the Baker Street & Waterloo Railway (BS&WR) on 10 March 1906. The Northern line platforms were opened a year later, as "Charing Cross", by the Charing Cross, Euston & Hampstead Railway (CCE&HR, now the Charing Cross branch of the Northern line) on 22 June 1907. At its opening this station was the southern terminus of the CCE&HR which ran to two northern termini at and Highgate (now ) tube stations.
