The crew of Conrail NB-31 has stopped their train at Teterboro station on NJT's Pascack Valley Line. Note that the consist includes mostly empty 86' auto parts box cars from the Ford Lead. There were not many dining options around this area at the time (unlike today), so the assumption is they walked across NJ-17 to the Bendix Diner for lunch. There were no midday commuter trains to interfere with at the time, either. A pair of SW1500s was not common on this job, but it did happen occasionally.
