Re: Another X29 Question -- Coupler Operating Release Levers

Jim and Barbara van Gaasbeek

Being ignorant of this matter, I’m not sure how a bottom-operated coupler actually worked.  In a top-operated coupler, gravity kept the pin in place, and one had to overcome friction to pull it.  With a bottom-operated coupler, how was the pin retained?  Obviously, gravity would help overcome any friction in pulling that pin.
