Band 6+: The chart below shows information about subway systems in three major European cities. Summarize the information by selecting and reporting the main information and making comparisons.

The given table describes size of Subway Systems in three different capital cities of Europe. Overall, London Underground, Paris Metro and Moscow Metro lead in three different fields: total track length, number of stations in operation and number of daily passengers, respectively.

Firstly, London Underground has the longest total track length among three cities, which is 408 km. It is more than Paris 94 km and Moscow 108 km.

Secondly, Paris Metro lead the number of stations in operation category, which is 300 stations. However, Moscow only have 182 stations in operation, just more than half of Paris subway systems while London only less than the lead 25 stations.

In contrast to those unimpressive figures, Moscow receives a large number of passengers every day (6.5 million passengers). It is more than double the number of passengers in London and more than Paris 2 million passengers.
