I have to mention the 150th anniversary of the London Underground: on 10th January 1863 the world's first underground railway opened to the public. The line ran from Paddington to Farringdon Street with intermediate stations at Edgware Road, Baker Street, Portland Road (later renamed Great Portland Street), Gower Street (Euston Square) and King's Cross. A year later the line was carrying more than 11 million passengers. Today a steam engine reappeared on that section of line; see herehere and here. Photograph from London Reconnections.
