at NS's Lehigh Line Three Bridge's (NJ) grade crossing on this Sunday afternoon? The holdup could be attributed to a procession of 20 to 25 MOW track equipment heading east. Both bicyclists and motorists could only watch until this parade finally passed. I would speculate that this equipment was the start of a tie replacement program that has been mentioned on other websites along the Lehigh Line. An interesting observation was that most of this equipment seemed fairly clean and lacked "NS" markings that I could see. Perhaps NS might have subcontracted this project out since one of these pieces of equipment had the name "Harsco" on the side.
