World's First Underground Railway Opens in London
London's rapid growth in the mid-19th century created severe street congestion that hampered commerce and daily life. Engineers proposed an underground railway using the cut-and-cover method to link major stations. The Metropolitan Railway's initial section from Paddington to Farringdon opened to the public on January 10, 1863, with steam-powered trains carrying thousands of passengers on its first day. The line featured gas lighting and wooden carriages. It immediately proved popular despite smoke and noise issues.
