@mark s posted:Yellowstone Vern - 19th century Pullman passenger trucks were all wood beamed! When full steel trucks became the norm would be around, say, 1910 (best guess). The Burlington Route used wood-beam trucks on their waycars into the 1970's. Believe they all used oak, which is quite sturdy. The beams were wood but the attached hardware was iron or steel.
I did not know that. In fact, I know very little about heavyweight Pullmans. Thanks, Mark. 👍
