Re: PRR FNA flat cars and twin 40 mm AA guns



Looking at the twin 40's when assembled as a unit ready to be installed on a ship, I am wondering if it wasn;t a center of gravity issue.  With the well the center of gravity would be lowered and avoid rolling the load.  This would be of particular concern on some "sharp" cures.

Looking over the PRRT&HS flat car book, I was reminded by the text that the F37 flat cars were built during WWII as a consequence of the nearly identical FNA cars being almost complete obligated to the U.S. Navy to ship twin 40 mm anti-aircraft (Bofors) mounts. Does anyone have any additional information on these loads, such as photos or a loading diagram?  I have looked at the mounts and wonder why a well flat would be needed since they do not seem to be particularly tall.
