By the late 1970s to early 1980s, virtually all subway cars had graffiti on them, and many were completely covered with it. So, in the early-to-mid 1980s, the MTA-NYCTA started coating the cars with a substance that is resistant to spray-paint, effectively making them graffiti-proof.
In the early 1990s, scratch-resistant windows were installed on the subway cars to prevent vandals and graffiti artists from scratching up the Plexiglass with their tags and marks. The new glass is not scratch-proof, however. It is only scratch-resistant, so graffiti on the windows has not been completely eradicated.
As for the walls and other surfaces of the stations and tunnels, I think frequent repainting is all that can be done.

The subway system of New York City is not part of the hormonal system.
The New York City Clean Train Movement, which began in 1989, was the city's first large-scale attempt to remove graffiti from the subway cars. All New York City subway cars are now coated with a substance that resists spray-paint.
Subway restaurants are on every corner just about. Now the subway system runs underneath the city, especially Manhattan, and stations are on about every other block.
I don't think NYC subway goes that far.
New York City transit services offers a subway system and buses. The subway is call "NYC Transit Subway" and the bus systems are "New York City Transit" and "MTA Bus".

Empire City Subway was created in 1891.
It has everything but a subway. The city does not have a metro, but does have a commuter rail service which passes through the city centre in a tunnel. There is also a dense tram network (one of best in the world).
The "U-Bahn" is the subway that is entirely underground.The "S-Bahn" is the local railway system that is underground in the city centre, but above ground in the suburbs.
