From Wikipedia:
In September 1938, during the Sudeten Crisis, when war appeared imminent, the Bakerloo and Northern Line tunnels at Embankment were temporarily sealed with concrete to protect against flooding through bombing. The blockage was removed after little more than a week once the crisis had passed. At the outbreak of World War II in September 1939, the tunnels were blocked again until electrically powered emergency doors could be installed in the tunnel mouths. They are each 330 mm thick, weigh about 6 tons and can resist about 800 tons of pressure.
