We are provided with the table, presenting the information regarding the underground railway systems, revealing their date opened, kilometres of route and passengers (in millions), per year, in six different cities. Generally speaking, the numbers are decreasing in the categories of the route’s length and the number of passengers while going forward in years.
Upon closer inspection, we can compare that London’s railway system, constructed in 1863, was 394 km in length and totalled 775 million of people used that per year, while in Paris the one opened in 1900 was smaller in kilometres, 199, but had significantly bigger number of passengers, 1191. Additionally, it is also seen that by the end of 19th, in other cities such as Kyoto, and Los Angeles, railways dated in 1981 and 2001 years, decreased dramatically in both length and number of passengers compared to the first aforementioned two.
Apart from that, some minor difference can be observed between Paris and Tokyo, having the route of 155 kilometres and counting 1927 million of people. In other words, an increase of its popularity among the citizens appeared with even shorter routes in the latter city.
The statistics help us to remark that throughout the time cities developed the railway systems differently. Particularly, by analysing the data, it might be concluded that the demand for trains has fallen down since 1863 so their routes have been shortened as well.
