Not seeking any "official comment" or anything, but if the train were moving at any significant speed, I'd be a little loathe to pull the emergency brake because that can cause injuries to anyone standing up not expecting it... On the M-7's we can use the emergency intercom, but on the earlier M-series cars or the bomb cars, would pushing the conductor signal button have accomplished stopping the train in a safer fashion than pulling the emergency brake or at least gotten the conductor to come to the door in question?
