thank you for the insight
Glancing at Rock Island diesel rosters, I don't think CRIP ever had a diesel 2031...
Not sure what you have. There are no FA's listed in CRIP's (Chicago Rock Island & Pacific) roster that match what you have, as far as color and number.
A Google search only came up with Lionel FA's, numbered 2031. It might be a Lionel "fantasy" scheme, but I'm not sure. If you do have a Lionel, "O" gauge, you might want to check out the other forums in here like Classic toy trains.
Just a suggestion.
Mike.
EDIT: What I did notice, while searching RRpicturearchives, is that the Alco FA's they had were built in the late 40's, and many were rebuilt by EMD in the mid 50's.
