The table provides information on underground railway systems in six major cities, including their opening dates, total route length in kilometres, and annual passenger numbers.
Overall, London has the oldest underground system, while Los Angeles has the most recently opened one. In terms of passenger numbers, Tokyo and Paris serve the largest populations, whereas Kyoto has the shortest route and the fewest passengers.
London’s underground system was established in 1863, making it the earliest among the six cities listed. It also has the longest network, covering 394 kilometres, and carries 775 million passengers per year. Paris, which opened in 1900, has a route of 199 kilometres and serves around 1.2 billion people annually, slightly more than London.Tokyo, which began operations in 1927, carries the highest number of passengers, at 1.9 billion per year, despite having only 155 kilometres of track. This indicates a very high passenger density per kilometre, suggesting a heavily used system.
In contrast, the American cities of Washington DC and Los Angeles have more recent systems. Washington’s underground, launched in 1976, covers 126 kilometres and carries 144 million passengers annually. Los Angeles has the newest system, opened in 2001, with only 28 kilometres of route, serving 50 million passengers each year.Meanwhile, Kyoto has the shortest system, at just 11 kilometres, and the lowest number of passengers, at 45 million annually. Despite its limited size, it still manages to support a significant number of users relative to its route length.
