Band 9: The table shows data about underground railway systems in six major cities with date opened, kilometres of route and passenger numbers per year in millions.

The table compares underground railway systems in six cities based on their opening year, route length, and annual passenger numbers.

Overall, London is the oldest and longest system, while Tokyo serves the most passengers. Kyoto and Los Angeles, being the most recent systems, are the smallest in both size and usage.

London, opened in 1863, has the longest network at 394 kilometers but serves fewer passengers (775 million) than Tokyo and Paris. Tokyo, with a route length of 155 kilometers, accommodates the highest passenger volume at 1,928 million annually, far surpassing Paris, which serves 1,191 million despite a slightly longer system (199 kilometers).

By contrast, Washington, DC (126 kilometers) carries just 144 million passengers yearly, while Kyoto and Los Angeles, with much shorter networks (11 and 28 kilometers, respectively), handle under 50 million passengers each.

In summary, older systems like London are larger, while newer systems like Kyoto and Los Angeles are smaller with fewer passengers. Tokyo excels in efficiency, serving the most commuters annually.
