The London Undeground started in 1863 when Victorian engineers and workers built the Metropoliten railway. This railway line went from Paddington Station to Farringdon Street Station, and steam engines pulled the coaches. Eleven more lines have opened since then. The world's first underground electric halway opened in 1890. This line went from the City of London to Stockwell in South London. The most modern line is the Jubilee line, which opened in 1979. Since the London Underground began, many other cities, such as New York and Moscow, have built their own systems.
