Well, we all know that the new Red & Orange Line trains feature the cams on the ceiling, but the question is do they rotate? I mean, do they all provide full coverage of the inside, including all of the doors? And just in case a thing like what happened on Sunday is about to happen agian, is there an alarm of some sort that would come on to alert the driver to stop the train, or at lease not let the train go from the platform until whatever is in the doorway is removed. Lord only knows that no one would want that to happen to them! Or be a witness to it.
