From the video description:

We are at Newark Penn Station, where we see Bennet Levin’s Pennsylvania Railroad E8′s, as they haul the 117th annual AARS special back to Race Street Yard in Philadelphia. The AARS is the American Association of Railroad Superintendents. This trip was sponsored by Conrail, and was run on Shared Assets up to Manville via the Lehigh Line, back on the Port Reading Secondary, up to Croxton, and back. Today’s consist is PRR E8′s 5809 and 5711 with 3 cars from the Morristown & Erie, as well as Warrior Ridge and PRR 120. Enjoy the sound of the rev of the EMD 567B’s of the E8′s. If you have any questions about the video, feel free to message me. Comments are welcome. The video was taken on July 21st, 2013.
