I recognize those cars!! For some reason, I have seen them sitting in the Kawasaki Plant (Yonkers) yard for quite some time. Reason why they would be there is beyond me, given Kawasaki does not produce freight cars, even for MOW use in passenger rail/transit agencies. Either CSX locals (out of Croton West Yard) B-749 or B-750 brought them here. I did not notice if these had them equipped when off the NYCT property, but most of NYCT's MOW flatcars and hoppers are equipped with trip cocks, I believe on both sides, to put the emergency brakes on should the cars roll past a red signal (with a trip up) or should roll past a portable trip. When the very rare instance they are taken outside NYCT property, I believe the trip cocks are removed.
Railroading is not a career, it's a lifestyle! Railroading........what other life would I wanna live?
