London Underground

EXPLORE # 148

The London Underground (also known as The Tube or, simply, The Underground) is a rapid transit system serving a large part of Greater London and some parts of Buckinghamshire, Hertfordshire and Essex in England. It is the oldest underground railway in the world, the first section of which opened in 1863 on what are now the Circle & Hammersmith & City lines and part of the Metropolitan line. In 1890 it became the first to operate electric trains. The whole network is commonly referred to by Londoners and in official publicity as the Tube, although that term originally applied only to the deep-level bored lines, along which run trains of a smaller and more circular cross-section, to distinguish them from the sub-surface "cut and cover" lines that were built first.

倫敦地下鐵（英文：London Underground）係英國倫敦嘅地下鐵，服務大倫敦、雅息士嘅艾坪林、赫福郡嘅三河區同屈福，同埋白金漢郡嘅齊爾滕，而家係由倫敦運輸（英文：Transport for London）營運。

倫敦地下鐵頭一段響1863年通車，係全世界最古老嘅地下鐵；第一架電氣化列車響1890年開始行，亦都係全世界最早。而家倫敦地下鐵有11條線同270個站，長400公里，係全世界最大嘅地下鐵網絡。
