The table below gives information about the underground railway systems in six cities.

The table chart provides data on subway train networks in some cities.

It is clear that

the newest metro is located in Los Angeles, which opened in 2001,

however

, it carries almost the least number of passengers, exactly 50 million. The longest underground railway system remains in London - it consists of 394 kilometres of tracks, and at the same time is the oldest system from the table. It opened in 1863. It is evident, that the largest subway in terms of passenger numbers is situated in Tokyo, it transfers 1927 million occupants.

On the other hand

, Kyoto has the smallest passenger flow, only 45 million. But these figures are not the only ones that seem interesting - Kyoto’s subway is hardly the freshest, it opened 20 years before Los Angeles underground.

Overall

, each metro is unique - in terms of the number of passengers, opening date, length of tracks, and so on. But it is safe to say that the entire infrastructure is developing very rapidly in the current context.
