Tonight I took an Ashmont train from Harvard to South Station (9:30-45). As we left about half the stops I heard a loud bang, but felt no vibration other than I would expect, nor did the train pause or slow. Admittedly an infrequent T user over 25 years, this was a first. I thought brakes, then I thought of slack letting out as a freight train starts. I was in the middle of the train.
