"Got to stay in touch even though we’re on the move/Keep your lines open, say, what’s new"

here's an old story i forgot to report:

one afternoon my green line train was stopped for 15 mins+ between kenmore and hynes convention. one simple action prevented anarchy: the conductor actually picked up his microphone and told us WHAT WAS GOING ON! i know, it's a crazy idea but i swear it's the truth. he not only told us why we were stopped (the signals were down or something like that) but he told us how long we should expect to wait. whomever this man was, he should be schooling his coworkers in common sense.
