While digging in some ATSF diagram books (ca 1920 & 1927) in the classification section they showed thier class codes as well as an ICC Class Code. Below is what they showed-
TYPE ICC SYMBOL
I have never encountered these classes by the ICC before that I can recall. I have an ATSF document dated 1912 prepared for the ICC that uses the ATSF classes and does not include the ICC ones. I have a lot of ICC valuation sections for equipment and other ICC documents and have never seen these used.
Is this something peculiar to ATSF? I have not encountered them in any other roads diagram or class books.
Thanks for any help anyone can provide.
