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 demonstrates information about underground railway systems in the given six large cities.

Looking from an overall perspective, it is readily apparent that the first and major railway system was opened in London, and the latest was opened in Los Angeles.

Turning to the details, the first railway among six cities was opened in London in 1863. The tracking path is 394 kilometers in length, making it the longest, and passengers per year are 775 million. The railway in Paris opened nearly 40 years later, and the length amounts to 199 km, which is more than 44 km in comparison with Tokyo. However, the number of travelers is higher in Tokyo (1928 million per year) than in Paris (1191 million).

It is clearly seen that the rail line in Washington, DC, was constructed approximately 50 years later than in Tokyo. The road of the tracking consists of 126 km, and total commuter counts every year exceed 140 million. The most recent rail lines were manufactured in Kyoto (1981) and Los Angeles (2001). Nevertheless, the pathway in Los Angeles is above 25 km and has 50 million people per year, while in Tokyo it is 11 km and only 45 million every year.
