The table illustrates the main information for the subway systems in six cities.
Overall, the early subway systems were launched in London in 1863 with 394 kilometres and 775 million passengers yearly. The recent one was opened in Los Angeles in 2001, which only goes for 11 kilometres and transports only 50 million per year.
Despite the fact that London’s underground was the first one, Paris and Tokyo railways, which were opened in 1900 and 1927 respectively, have recorded more passengers than London. In addition, 1191 million passengers use Paris railway per year, while 1927 million use Tokyo underground each year.
The development of railway systems shows a gradual decline in the kilometres of routes. London was 394 kilometres in 1863, while Los Angeles was only 28 kilometres. Kyoto underground system is considered the smallest one in the table in both routes and passengers, where it has just 11 kilometres and transporting 45 million passengers.
