And the world's biggest metro system too!

And here it is. Shanghai's Metro has 14 lines, and the total length is 588km. There are 364 stations, and its ridership is over 3 billion per year.

As ever, it depends on exactly how you measure these things. Shanghai's got the longest system. Beijing has a slightly higher ridership, and New York has more stations.










Anyway I was impressed. It was very easy to navigate, excellent value, fast, clean, reliable. I used it a lot.
