At least the r32's weren't vandalized prior to retirement. Lol!!!
As for the r46's, I just don't know if it's "railfans" that hate the r46's that are causing these acts of vandalism or if these vandalic acts are caused by teens that have irresponsible parents.
Either way, the MTA and NYPD need to impose heavy fines or jail time to those who are vandalizing trains and buses.
Remember, if it's easy for a crazy teen to vandalize a train, then it will also be easy for a terrorist to put a bomb on a train. Safety first.
