The table below gives information about the underground railway systems in six cities ql55
Various data about the subway system can be reported. When the underground railway system began to work, the magnitude of routes and the number of travelers who use this system for six cities are listed in the given table.
Overall, it can be observed that the size of older systems is more than the new ones. As a result, the cities which open the railway system in recent years sever fewer passengers.
According to data, London has the oldest railway system with the largest routes. However, Tokyo's railway is 239 kilometers less than London, but the number of travelers who use the subway in Tokyo is considerably higher than London. Albeit the railway size are close for Paris, Tokyo, and Washington DC, but the number of people who use the subway is only 144 million in Washington DC, while there are 1191 and 1972 million in Paris and Tokyo, respectively.
The data shows a significant drop in the railway size and the passenger number for railway systems opened since 1981. As it can be seen, the route's kilometer for Kyoto and Los Angeles is 11 and 28, which is dramatically less than other cities. For this reason, the passengers who use this system have a low number in these cities, too.
