When Tim Murphy, and MBTA conductor who NORMALLY drives Mattapan trains but on Sunday was driving the green line, realized he was between Hynes and Copley at 2:49, he knew he had to say something.

4 years before, at that very day, at that very time, both bombs went off at the finish line of the Boston Marathon right above where they were. He gave a touching speech and offered a moment of silence. Read the experience in his own words below-

"4 years ago, at this exact time, about 30 feet above this spot, the first of two devices went off and changed our city forever. Before entering Copley I would just like to observe a moment of silence to remember those who were lost and to think of those of us who continue to struggle on a daily basis from the effects of that day. On a more personal note for those running on Monday, from someone who was there in Copley Square when it happened, I can't even begin to tell you just how much it means to us that you continue to support our city. Thank you a thousand times over."
