The tension on the knuckle translates into sheer stress on the pin.  You can
see an animation of coupling/uncoupling action at
http://www.trainweb.org/railwaytechnical/design%20details.html#Couplers
Cast iron drawbars where rated at 250,000 to 280,000 lbs.  Newer steel units
can withstand up to 500,000 lbs.  AA Krug has a discussion at
