The table provides information on the dates underground railway systems were opened, their route lengths in kilometers, and the number of passengers per year (in millions) in six major cities.
From an overall perspective, it is clear that London is the oldest system and has the longest route, while Los Angeles is the newest and Kyoto has the shortest route. Tokyo and Paris attract the highest number of passengers annually, whereas Washington DC, Kyoto, and Los Angeles have relatively lower passenger figures.
London, established in 1863, has the longest network at 394 kilometers but serves 775 million passengers annually, which is not the highest figure. Paris, opened in 1900, has a network 195 kilometers shorter than London’s but accommodates significantly more passengers at 1,191 million annually.
Tokyo stands out for having the largest number of passengers, with 1,928 million per year, despite its route being only 155 kilometers long. By contrast, Washington DC, opened in 1976, has a route of 126 kilometers and serves 144 million passengers yearly. Kyoto, which began operation in 1981, has the shortest route at 11 kilometers and the lowest number of passengers, at 45 million per year. Finally, Los Angeles, the newest system (opened in 2001), has a route of 28 kilometers and carries 50 million passengers annually.
