What is the world's largest subway system? The chart below, created by Leon Markovitz of Dadaviz, shows there are a few ways to answer this question.

The New York City subway has more stops than any other system, with more than 400 stations – double the number in Mexico City, Moscow, Berlin and Tokyo.

When it comes to total length, however, the Shanghai Metro wins as the world’s longest. Both Shanghai and Beijing has more than 300 miles of metro systems, most of them installed in the last decade.

The Beijing Subway also qualifies as the system with the world’s largest ridership, with roughly 3.5 billion people riding the subway in 2014.
