The table provides information about underground railway systems in six cities, comparing the year each system was opened, the total kilometers of route, and the annual number of passengers in millions.
The oldest underground system is in London, which began operation in 1863. It also has the longest route, covering 394 kilometers, and serves 775 million passengers annually. Paris, which opened its metro in 1900, has a shorter network of 199 kilometers but handles more passengers than London, with 1,191 million users per year. Tokyo, which started in 1927, has the highest passenger usage among the six cities, with 1,927 million annual riders, despite having a shorter route of 155 kilometers.
In contrast, the systems in the United States are more recent and less heavily used. Washington DC’s metro opened in 1976, spans 126 kilometers, and carries 144 million passengers each year. Los Angeles has a relatively new system (opened in 2001) with 28 kilometers of track and 50 million passengers annually. Kyoto’s system, which opened in 1981, has the shortest route—only 11 kilometers—and the fewest passengers, with 45 million per year.
In summary, older systems like those in London, Paris, and Tokyo tend to have more extensive networks and higher usage, while newer systems such as those in Kyoto and Los Angeles have more limited reach and serve fewer passengers.
