The table compares the metro systems of six cities in terms of the establishment dates and total commuting lengths and also, number of commuters transported annually (in millions).
It is noticeably observable that the foundation of London’s urban train system dates back to more than a century ago, making it the oldest train system amongst other cities. Although the Tokyo’s subway system is relatively newer than the one in London, it accommodates significantly largest volume of passengers.
To begin with, London is the oldest system having founded in 1863, and also is the vastest by covering more routes at 394 Km. Paris’s metro, is ranked second having established in 1900 and covering 199 Km of route. The next four systems Tokyo, Washington, Kyoto and Los Angles have started their activity later than of Paris and London respectively, and their covered lengths reduces proportionally depending on their date of utilisation, with exception of Kyoto, which appears to be older than Los Angles, but covers less than half of that (28 Km) with an average of 11Km.
On the other hand, number of travelers doesn’t seem to be aligned with the trend in other statistics. Tokyo and Paris which are ranked first and second respectively, have by far the most efficient train system with accommodating 1927 and 1911 million people annually respectively. London is the third most congested system with transferring 775 million people every year followed by Washington, Kyoto and Los Angles with just under 150 million individuals. Interestingly, by having severely less covered railways than of Los Angles, Kyoto metro accommodates slightly less commuters than Los Angles with 45 million.
