The table shows the detailed information regarding the underground railway systems in six cities, namely, London, Paris, Tokyo ,Washington DC, Kyoto and Los Angeles.
London has the oldest underground railway system among the six cities which was opened in 1863. And Paris is the second oldest, and it was opened in 1900. This was then followed by other four cities, namely,Tokyo,WashingtonDC andKyoto with the opening date of 1927, 1976, and 1981 respectively. As forLos Angeles, it is the last one in this table to have its own underground railway system (opened in 2001).
In terms of the size of the railway system, Londonenjoys the largest underground railway systems, with 394 kilometres of route in total, which is nearly twice as large as that in Paris(199 kilometres). Kyoto, in contrast, has the smallest system, for it only has 11 kilometres of route, which is nearly 1/36 of the route of London. The other three cities(Tokyo, Washington DC, and Los Angeles) have 155, 126 and 28 kilometres respectively
Interestingly, Tokyo, which only has 155 kilometres of route, enjoys the greatest number of passengers per year, at 1927 million passengers. The system inParis has the second greatest number of passengers, at 1191 millions passengers per year. The smallest underground railway system,Kyoto, serves the smallest number (only 45 people).
In conclusion, the underground railway systems in different cities vary a lot in the opening date, the size as well as the number of passengers served per year.
