It was at the Brotherhood Church on Southgate Road, Hackney, that Lenin, Trotsky and Stalin met for the 5th Congress of the Russian Social Democratic Labour Party in 1907. The site of the now-demolished church is today home to a Tesco Metro. Other major events taking place in the city in that year included the first large procession by the suffragettes, the opening of Strand station (later to become Aldwych, and no longer a stop on the underground), and Hampstead tube station opening.

Aldwych Tube Station opened in 1907, but closed for the duration of the second world war. It was used to hide and transport museum pieces, and provide shelter from aerial bombardments. It reopened after the war, then closed permanently in 1994 due to lack of use. Since then it's been used as a film location, and you can occasionally tour it. Source Acidcow

Delays on the line: It was at this point that the Charing Cross branch began in earnest. Severely held up by funding problems, it finally opened in 1907 as the Charing Cross, Euston & Hampstead Railway. The CCE&HR snaked from Golders Green and from Highgate (then the name for Archway station) down to Charing Cross, with an easy extension then linking it with the relative hub that was Embankment.
