"Rocking" trains is not a new phenomenon. Back in the 1960s, I was living in suburban Boston and rode New Haven's Needham line to Back Bay in Boston. One day, I spotted a couple of punks on a bridge overlooking the Bird's Hill station and they were tossing rocks. I alerted the conductor of an incoming RDC, and fortunately, the Budd car did not get hit.
