The table given shows information about subway networks in six areas: London, Paris, Tokyo, Washington DC, Kyoto and Los Angeles.

Furthermore, Tokyo underground railway system has the busiest station with more than 1900 millions and it was established in 1927 which has 155 kilometers of route.
As is given in the table, the city Los Angeles has the newest underground railway system, which was established in 2001 and it is the second least exploited with 50 million people for every year and also the second shortest length with 28 kilometers, two times that in Kyoto. Meanwhile, the system in Kyoto was used earlier than the one in Los Angeles, in 1981, stands the last rank with 11 kilometers length and 45 million passengers per year, . On the contrary, the train network in Washington DC was built in the year 1976 has the greatest amount of passengers and the longest route ( 126 kilometers and 144 million passengers per year ) in three cities: Washington DC, Kyoto, Los Angeles
