The table below gives information about the underground railway systems in six cities. Summarise the information by selecting and reporting the main features and make comparisons where relevant.

The given table reveals data about the underground

railway

systems in 6 major cities relating to the data opened,

kilometres

of route and

passengers

per year.

Overall

, what stands out from the table is that Tokyo accounts for the highest proportion of

passengers

during the year. The oldest

railway

system is

London

which is

also

the longest among the others. Moving into a more detailed analysis, it is obvious that in most cities

railway

systems were opened in the 1900s with the exception of

London

and Los Angeles (in 1863 and 2001 respectively). The length of Kyoto and Los Angeles formed very little share of the total, 11 and 28

kilometres

in turn. There is a little margin between Tokyo's and Washington DC'c routes, as the former is accountable for 155 km, and the latter is less than it by 29 km. The longest

railway

system built in

London

was 394

kilometres

, whose figure was twice as high as that of Paris, 199

kilometres

. In terms of

passengers

, Paris and Tokyo were the busiest railways with a share of more than 1 thousand. The third was

London

which was merely 775 km.

Consequently

, Kyoto and Los Angeles had the lowest contributions (45 and 50 respectively). At

last

, Washington's

passengers

comprised of the total by only 144 people
