As you are doing various switcher repaints at the moment I have a proposal: SW1200 Number 5 and 12 of the Quincy Railroad Number 5 serves the shortline between the Sierra Pacific Mill and Quincy Junction near Portola in Northern California. Number 12 now operates for the Western Pacific RR Museum in Portola.
Not a well known RR and very special, but it would perfectly fit for my WIP Feather River Canyon Route. If you have the time and can do the repaints it would be wonderful.
