The London Underground is a classic underground urban railroad found in London, Britain . As well as shaping the town of London above it, the London Underground also influenced urban railroads around the globe. Many countries modeled their tube systems after the London Underground. The London Underground is also called the Tube, thanks to the characteristic shape of the train tunnels. The total network which comprises the London Underground is 253 miles ( 408 kilometers ) long.

976 million rides are taking on the London Underground every year in 4,070 tube vehicles. The London Underground started in 1863, when service was first opened between Paddington Station and Farringdon Street. The system continues to expand, with regular constructions of new lines and retrofitting of old ones to better serve the users of the London Underground. Construction on the urban train line system, which came to be called the London Underground, commenced in the Victorian time responding to inflating traffic congestion.

The growing population made traveling in London terribly complicated, and that was thought that an underground train line would figure out many congestion issues. The London Underground expanded swiftly, and included twelve separate lines by 2006.
