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

A glance at the table given provides the comparative statistics on the underground railway systems of six different cities (London, Paris, Tokyo, Washington DC, Kyoto and Los Angeles) in terms of date opened, the length of route measured in kilometers and the number of passengers per year. From the overall perspective, it can be clearly observed that the more recently established railway stations are considerably shorter than the older ones, with the exception of Los Angeles’s which is longer than Kyoto’s built earlier. The most significant quantity of passengers per year could be seen in the metro of Tokyo, while in stark contrast, Kyoto served the smallest number of people among other participants. With respect to the underground railway station of London, it was found in 1863 and considered the longest among others comprising 394 kilometers. The second leading position in terms of the length of route belongs to the second oldest subway of Paris (1900) with 199 kilometers. Despite that Washington DC’s railway was opened 50 years later after Tokyo’s, they have a slight difference in the breadth of the road at about 30 kilometers. As for the subways of Kyoto (1981) and Los Angeles (2001), they both covers 11 and 28 kilometers respectively. Regarding the number of passengers per year, Tokyo serves the biggest quantity of people, which is 1927 million of people. With 1191 million, meanwhile, the Paris metro has the second largest carrying capacity. On the contrast, London system was equipped to carry 775 millions of people while Washington DC’s railway – 144 millions. The systems with the smallest capacities are those of Kyoto and Los Angeles, transforming 45 and 50 million per year respectively.
