Its too bad you never saw the Washington DC subway, the second largest in America. Metro (the subway's name) prides itself on being one of the cleanest subways in the world. I have yet to ever see ANY graffitti at all on a station wall or a train for that matter. Trash is almost non-existant even in the stations where the trashcans have been removed. The Metro police are very dilligent and sometimes almost too dilligent. There is a famous story about them arresting a 12 year old girl who was eating french fries on the Metro (eating on the subway is illegal).
It isn't really fair, however to compare the DC metro to NYC, London, or Paris, as the metro is only 25 years old and combined the elements of those three systems with other ideas (for the most part, it is impossible to touch a wall in a subway station with your hand) to create a clean, and somewhat effective system.
