Ielts TASK 1, help me check my essay, thank you.

The table represents six cities in terms of date opened, route's length and passengers every year.
Overall, London is the earliest city building underground rail networks and has a longer route than the remaining cities. However, this means of transport in Tokyo and Paris are more develop and popular than the other four cities.
According to the table, in 1863, the underground railway systems were set up in London with 394 kilometres which are longer than the ones in Paris for 2 times and Tokyo for 2.5 times. In contrast, these two cities have more people travelling underground railway every year than London and others. In Tokyo, the number of passengers was 1927 million each year, accounting for nearly one second of a total of six cities.
Conversely, Kyoto and Los Angeles are the latest cities opening the underground rail systems and only amount around one per cent of passengers per year. Whereas, the ones in Washington DC were built earlier and has roughly three times as many as the number of people travelling underground railway in the two above.
