Charlie;
Good point, and I found a whole bunch of correspondence that led to PRR applying things like double flooring (their term), and/or 24” steel plating for interior sides, to keep hot coil loads, for one, from torching floors and linings. Before that, poof.
It didn’t entirely solve the problem.
For wooden-floored gons, a layer of cinders was applied around steel blocking, to keep the heat from the floor, and that didn’t always work, either. Plenty of cars burst into flame in hot roll or slab service.
There were series’ of cars:
Also in hot roll service, that I’ve been trying to find more info on. If you have photos of any of these, I’d sure like to see them!

Sorry for repeating if this has been observed already, but even an “all metal” box car or reefer had a wood floor and liner that would burn very nicely. Charlie Vlk

Cars used for hauling ammunition or other explosives which had wooden floors were required to be equipped with spark shields. These were sheet metal plates placed above the wheels to help prevent sparks from cast iron brake shoes from catching
the car floor on fire. This is included in the Interchange Rules. Rule 88 I think.
