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.
