Seoul’s Subways Lack that NYC Charm

Could you imagine a subway system in a bustling city that is clean, quiet, and relatively polite, a place where commuters cooperate and litter is nonexistent? It exists, just not anywhere near New York City. In Seoul, Korea however, their trains and stations are virtually spotless. No one even doodles funny things on the billboards, making it one of the most orderly and convincingly boring transit systems ever.
