Randy;

This is a PRR F25C dedicated diagonal loading car, for boiler heads or plate steel wider (or taller) than the maximum of the clearance diagram.  Loads were tilted up diagonally, against the timbers, and secured with chains running from the floor, up over the top of the load, and attached to the timbers.  The entire load and car had to fit inside the clearance diagram.  The loaded cars were shipped in “High and Wide” shipments in certain trains, and were continuously checked along the way to ensure no load shifting occurred that would cause a load to hit something, like a bridge entry, tunnel entry, etc.
