Compromises: Catenary Car A16502 needed to be hauled away from Track 2 at Princeton Junction Station on Tuesday, August 27, 2019. In order to couple it with the Amtrak engines sent to haul it away, it was necessary for a crew to attach a compromise coupler. With workers present on the right of way, an employee was posted with a "Workers Present" sign to ensure that passing trains alerted the crew when approaching this location.
