the first subway in asia was the subway in tokyo, japan. the first section, part of the ginza line, was opened in 1927. now, there are 13 lines run by two different companies (tokyo metro and toei subway), and many trains on these lines, called "through trains", run directly onto regular japanese railways. many other cities in japan have subways of their own, like osaka, kyoto, and nagoya. in china, the first subway, beijing subway, opened in beijing in 1969. other cities in china began to build subways, including tianjin, shanghai, and guangzhou. these systems, especially beijing with its 18 lines, have become some of the largest and longest in the world. for example, the shanghai metro had only one line when it opened in 1993, but today has 19 of them. both the beijing and shanghai systems have over 500 kilometers of track. other cities in asia with big subway systems are taipei, taiwan (taipei metro), seoul, south korea (seoul metropolitan subway); delhi, india (delhi metro); and singapore (mrt). three of singapore's mrt lines, along with three smaller lrt lines, are automatically operated without a driver. a few more metro systems that run this way are london's docklands light railway; the skytrain in vancouver, canada; and the dubai metro serving dubai in the united arab emirates.
