When I got on on the second car of an inbound trolley at Hynes early this afternoon, it was fairly crowded, and the back half of the car was packed with high-school kids.
About halfway between Arlington and Boylston, WHAM, the train slammed to a stop. Some guy began yelling "Is everybody OK?" The operator got on the PA and asked the same question. Everybody was. And then the operator got back on and said "You kids back there better stop fooling around, somebody's going to get hurt."
A few seconds later, the train began moving again. WHAM, the train slammed to another stop. This time, we just sat there as the operator got on her telephone and began talking to somebody. "Excuse me, are we going to be moving soon?" one guy asked. "I have a bus to catch." Just then, a beefy inspector-type dude got on the train and made his way to the back. I couldn't hear what he was saying, but he was talking to the kids and pointing to the levers above the doors back there. A couple of the kids just shook their heads, as did some random woman back among them.
Inspector Dude strode to the front of the train and yelled: "This train is coming out of service. Nobody wants to admit anything, so we're taking this train out of service." The train inched into Boylston, the doors opened up and we all stepped out, as the Voice of the T guy's voice came on to apologize for the train being taken out of service.
