April 30, 2018. The crossing at Penn Grove is kind of an accident looking for a place to happen. There are multiple warning lights, flashing signs not to stop on the tracks, and the train slows from 79 mph to 49, but with the buildings obscuring vision, rush hour traffic backups from a busy intersection just the other side of the hill, and the tracks diagonally crossing a street intersection... even at 49 mph the appearance of the train is sudden.
