So there are two plans from the 1950s that originally used 15-inch-radius curves. Were 15-R curves more commonly used "back then"?
Yes, and sometimes as small as 13"R. Most modelers didn't have the extra room for large train layouts back then so most layout designs were small (the 4x8 being very common). In fact, Atlas's 22"R was considered a luxury back then. Of course, we didn't run (nor were they commonly available back then anyway) UP Big Boys or Challengers on 4x8 layouts but the popular little 0-4-0 "Docksides", "Little Hustler" diesels, and 40ft freight cars operated just fine on the tighter curves.
