Underground passenger railwayIn 1863, London's Metropolitan, the world's first underground passenger railway, opened to fare-paying passengers. The four mile, 33-min route had seven stations between Farringdon St. and Paddington. At 6 am, six steam locomotives each with four carriages, left 15-min apart, and made a total of 120 journeys in both directions, carrying over 30,000 passengers. Charles Pearson first proposed the underground railway to relieve congestion in London. The Metropolitan Railway Co. was founded in Aug 1854. After financial delays, the first shaft was sunk at Euston Square, in 1860. The tunnel was built by "cut-and-cover" whereby a trench following the route was dug to the rail level, then covered with beams and a new surface.« |
