The table illustrates the data about underground railway systems in six major cities with date opened, kilometers of route and passengers number per year in millions.
Overall, despite Tokyo having relatively shorter network than London, serves the highest number of passengers in millions per year. On the constrast, newer systems like Kyoto and Los Angeles receives the lowest number of passengers in major cities.
London with the oldest railway system opened in year of 1863 has a route of 394 kilometers per year, accumulating 775 millions of passengers.

Tokyo opened in 1927 routing for about 155 kilometers, and accommodates the most passenger with a 1928 millions per year.
On the contrast more recently established systems carry far fewer passengers. The city of Washington DC starts to regulate in 1976, with 126 kilometers per route, serves 144 million annually. Kyoto opening in the year 1981 routing for about 11 kilometers only accomodates 45 million of passengers yearly. Los Angeles with the most newest established railway system only routing 26 kilometers and only transports 50 million passengers.
