The provided table presents data on the underground railway systems in six different cities, including the year of establishment, the length of the route, and the annual number of passengers.
Overall, it is evident that the older underground systems, such as those in London, Paris, and Tokyo, have larger route lengths and serve significantly more passengers compared to the relatively newer systems in Washington DC, Kyoto, and Los Angeles.
London, the earliest system established in 1863, boasts the largest route length of 394 kilometers. Following London, Paris, established in 1900, has a route length of 199 kilometers but serves more passengers annually than London. Tokyo, with a route length of 155 kilometers, accommodates the highest number of passengers at 1927 million per year.
On the other hand, among the newer systems, Washington DC, opened in 1976, has the longest route at 126 kilometers and serves the most significant number of passengers, surpassing Kyoto and Los Angeles, with 45 million and 50 million annual passengers respectively. Despite having a shorter route length compared to Kyoto, Los Angeles serves more passengers, indicating higher usage of its underground system.
