Reply to "Heavyweight horse cars and baggage cars. Drains?"

I do not know about horse cars, but in the Santa Fe baggage car i am familiar with the side doors ran in slots below the floor level. At the ends of these slots there were drain pipes. Maybe 1” pipe that ended only a few inches below the underside of the floor. These drains would have picked up water from the outside of the door when it was open and any seal leakage. If this was not drained it would have frozen and jammed the door in cold weather. I do not remember how these interfaced with the fish racks. These were no fish racks in the doorway, just between the doors.
