The table presents data on the underground railway systems in six major cities, highlighting the year each system opened, the total kilometers of route, and the number of passengers per year (in millions).
The oldest system is in London, which opened in 1863. It has the longest route, covering 394 kilometers, and serves 775 million passengers annually. In contrast, the Los Angeles system, which opened in 2001, has the shortest route of 28 kilometers and the lowest passenger count at 50 million.
Tokyo’s underground, which started in 1927, handles the most passengers, with 1928 million annually, despite its route being only 155 kilometers long. Paris, which opened its system in 1900, serves 1191 million passengers over 199 kilometers of track.
Washington, D.C.’s system opened in 1976, covering 126 kilometers and serving 144 million passengers. Kyoto, with its system inaugurated in 1981, has the shortest route (11 kilometers) and serves 45 million passengers annually.
Overall, there is a notable variation in the age, size, and usage of these underground systems, with newer systems tending to have shorter routes and fewer passengers, while older systems like those in Tokyo and Paris handle significantly higher passenger volumes.
