I grew up in NYC and I think it has a lot of problems that have prevented me from moving back there since college, this said... NYC has the largest train system in the entire world, especially when you combine the various nearby train systems that aren't a part of the main subway like LIRR, NJ transit, path and Metro north (in China which technically is longer they count long distance commuter rail). The subway alone has more stops than any train system in the world.
