From Ted Cullota's series of books, "Focus on the Freight Car
vol ten other freight car types" has some great photos of various tank cars pictured from the 1930s. One of particular interest to me is the Rio Grande Oil Co., R.G.O.X. 234. The 10000 gallon tank car is a type 17 GATC design.
I would like to know if any of these cars date back to 1928 and if so, what numbers were assigned?
Thanks for any help for this project.
