Note that these cars were designed at a time that engineers (the design kind) were trying to figure out how to make cars resistant to excessive bending (or failure), and had not yet figured out the best way to do it. PRR’s answer was to rivet multiple strips of steel together to resist that bending, resulting in the look shown in these photos. The top down of 425018 is instructive.
Since the sides adjacent to the hole were weaker, it was PRR’s intent to spread the load over the ends, like in photo of 425004.
B&M had similar intent on their well cars, which were used for big GE products. Big girders with end feet transferred the load over the ends, like 425004.
I had the luck to see an ex-PRR F37B (IIRC) on DoD property at one point, and crawled all over it. What an anachronism!
Eventually, PRR went to GSI for a better replacement, the F49 shown. What a beautiful car!!!

Hi Elden and List Members,
Thanks for the great explanation of this situation and the multiple images.
Elden did not have a PRR class FN image to share with us, but there is one at the link below...
If I am not mistaken, the LV had a similar car. I have a brass model that I’ve painted, though it’s in a box and I’ve not seen it for quite a while.

Thanks for the PRR photo Schuyler. It proves exactly what I had posted earlier. I believe
The car in your photo has no floor at all and has no need of one. Look at how the short,
Cylindrical load is carried. It is “pinched”, if you will, by large timbers on the regular deck
of the car. Those timbers are then heavily braced to be sure the load cannot drop any lower.
To be doubly sure you will note that there is additional timbering just below its extreme
Height. Thus no floor was needed.
Cordially, Don Valentine
