The question below came up on another discussion board. Anyone have an answer?
"I am looking for information on experimental freight cars built from concrete in the 1910's and early 1920's (Joseph Baerman Strauss being one of the main characters in these developments) and also on composite cars built in the 1960's (North American Tank Car Corporation) and 1980's (ACF's Glasshopper car). Nothing came out of these experimental cars so documentation is scarce. Can anybody help?"
