Many years ago, I was visiting a steam line in Scott, Arkansas and they had an old 1940 something Chevy Suburban(?) with flanged wheels. I was really taken with the old car, it also had a steering wheel. The shop foreman explained to me about how the wheel worked the manual brakes just like a brake wheel on a freight car. Since then, any railcar I build has a steering wheel and I get to explain to others why it's so. That's a great bit of info you found, keep looking for arcane information....we all want to know.

Well. I am going through the whole set, started with the earliest (1905) and currently in 1922. There are many missing issues but every available one has at least one piece about railroads, sometimes stuff so crazy that I wonder about the mental health (or kind of government contract) the inventor had. The problem with those mags is that they are alphabetically indexed, great if you know what are you looking for. Just go and check EVERY ONE!.
