I was on the Red Line leaving Alewife. There were only three other people in the car with me, when the train stopped right after leaving the station. This happens fairly often, so I didn’t think much of it. Then the lights turned out. It was rather eerie just sitting there in the dark with only a few other people. I took out my camera and snapped a few pictures. Soon after, the lights turned back on and the train started moving again, without a word from the driver.
