Look again, Tim. The earlier drawings show a CROSS-SECTION of the running board with wood grain. I hope that convinces you that it is not steel. The drawing you cite is indeed a 1941 drawing, but look at the prior ones. Or do you think the 1-3/4-inch minimum thickness refers to steel, either solid or grid? No running board made of steel was ever that thick. And you can quit trying to be insulting by saying "if you say so." That implies you doubt it is true, but the drawings are right there for anyone to see.

I don't know how thick (deep) they were -- the drawings only say "steel grating to meet AAR requirements". Certainly I have seen steel grate walkways on modern tank cars that appear to be at least that thick. Tim O'

For "modern" tank cars, OK, if you say so. But the 1956 Cyc shows the Apex running board grid bars as 1 inch deep. That ain't 1-3/4 inches. And in any case, photos before 1940 are hard to interpret as other than wood running boards and dome platforms. Unless you want to quibble on that too.
