Yes, $, for many. Cor-Ten was not cheap. Other steels, ditto. USS alone produced many different steels to accommodate end user needs. I saw a financial analysis on this in PRR correspondence, at one time.

Dennis; re: paint, I see your point. The mid eighties were the period that paint on the roofs and hoods of cars (automobiles) performed very poorly (flaking, fading and otherwise failing). Thanks for pointing that out.
Eldon, I’d read about “copper bearing steel” used in N&W coal hoppers in the twenties and thirties. The railroad looked into CorTen steel at some point in the STMFC era, but didn’t use it, for reasons I don’t recall (value for $, probably). I didn’t pay much attention to later non-STMFC chapters of Andrew Dow’s excellent book on the topic. Perhaps the Virginian was a different story.
Thanks for the replies.

Steel performance did vary over time. The “coal” (and other) RRs were constantly looking for something better to build their hoppers from, particularly for slope and side sheets. I have read plenty of correspondence in which this exact issue is discussed. Over time, the steel companies supplied the RRs and builders, with steel whose properties were increasingly resistant to corrosion, “Cor-Ten” being one USS product. Hoppers rotted more quickly than others, due to their prevalence in hauling coal, which generated sulfuric acid, for one. Hoppers did get better at not corroding as fast, with new formula steels.

But paint did. The National Environmental Protection Act of 1970 was not kind to paint manufacturers, forcing them to stop using a lot of traditional materials, all to the detriment of paint performance.
