Passenger car locking center pin variations.
Posted by ScottyW on Thursday, June 16, 2022 3:03 PM

Today, my old shop at North Walpole (Green Mt. RR) messaged me about helping to figure out the locking center pin on one of the passenger fleet.  The car is a former NYC )opera) baggage car with the swinging end door.  The center pin access is from inside the car but the crew was having a time getting things loose and figured out.  I had not encountered this style before and am wondering if anyone has a mechanical drawing.  It is a variation of the three-piece desing in older cars that hs two outer locking halves with the center straight plate dropped down between them to keep them in place.  The NYC car uses a foour-piece where the center plate is a triad and there are three locking castings instead of two.  Works exactly the same but just has that different arrangement.  
A drawing of the four piece would be ideal, as we already have a great drawing of the normal three-piece.  Image of the center plate remove is shown here. Center piece of a four-piece locking center pin.

I think your best bet is to contact NYCSHS and see if one of their collections has the pin drawings.  They might extend you a discount since you're a legitimate operator.
