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

The following chart describes some important nations of the First World and relevant information about their railway systems. The presented lecture will elucidate inferences related to data opened, kilometres of route and passengers per year.

To begin

with, it can be seen that the first railway system was inaugurated in 1863,

this

design was carried out in London and it has been maintained

as well as

its beginnings. The newest structure was built in Los Angeles, state of America, in 2001.

In contrast

, the difference in age is estimated in more than a century.

Thus

, it demonstrates how efficient is the train.

Secondly

, the kilometres built depict that the biggest systems are the oldest ones, it could proportion unique conclusion as the older the more spread.

Nonetheless

, there is not a direct proportional relationship between those variables.

For instance

, the Kyoto system is older than Los Angeles by 20 years,

however

, the American scheme has a road 17 kilometres more than the Japanese.

Finally

, the amount of people is the most important factor to consider.

Hence

, Tokyo is positioned as the king of the Trailways, driving more than 1900 million passengers per year.
