Scratch graffiti on seat back
There is virtually no spray paint graffiti to be found anywhere on the rail system. Perhaps this is because law enforcement is on the lookout for this type of vandalism, or maintenance workers are quick to remove it. Scrath graffiti, on the other hand, is prevalent. It is more permanent, and is visible on most surfaces on board the trains. Unlike spray paint graffiti, which requires a spray paint can, virtually any sharp objects can be used, including ones that are small, easily concealed, and inconspicuous.
