I talked to a few of my friends, and we think it is a bad repair of a burned-out wooden floor. The MRY is south of the PRR/Mon, which hosted many mills producing hot steel products like ingots and hot coil. Correspondence has many examples

I have a number of bed order cars. They usually cause much consternation.
