Tokyo

Tokyo the world's most extensive rapid transit system in a single metropolitan area, Greater Tokyo. While the subway system itself is largely within the city center, the lines extend far out via extensive through services onto suburban railway lines.

As of June 2008, the entire network of Tokyo Subway has 274 stations and 13 lines. The Tokyo Metro and Toei networks together carry a combined average of over eight million passengers daily. Despite being ranked first in worldwide subway usage, subways make up a small fraction of heavy rail rapid transit in Tokyo alone—only 274 out of 882 railway stations, as of 2007. The Tokyo subway at 8.7 million daily passengers only represents 22% of Tokyo's 40 million daily rail passengers.
