This table shows data about the undergrounds in London, Paris, Tokyo, Washington, Kyoto and Los Angeles in terms of dates of opening, length of routes and number of passengers.
It is noticeable that the oldest railway system of the six given was opened in London in 1863 while the newest system, the Los Angeles underground, was founded almost a century and a half later in 2001. Four other undergrounds were started in the 20th century : two of which were Paris and Tokyo at the beginning and the other two at the end of the century.
When we compare the lengths of the railway systems we can see that length of route almost corresponds to date of genesis. The longest is the London underground at a route of 394 kilometers. The next one is Paris with the length of the system being half of that in London. The shortest system is in Kyoto at 11 kilometres. Although Los Angeles is the most resent, it almost 3 times as long as Kyoto’s one at 28 km.
A close examination of the number of passengers reveals that the most popular are the ones in the Tokyo and Paris with 1927 and 1191m passengers per year respectively, while the less used are Kyoto and Los Angeles at 45 and 50 million respectively.
To sum up, the table show us that the length of undergrounds mostly depends on the dates of opening, however the numbers of passengers were not relevant to the dates but possibly to the population of cities.
