I can spend hours thumbing through the Dorman photo collection on the Friends of the C&TSRR website! Anyway, as I was browsing I came across two photos of what appears to be a D&RGW 3000-series "economy door" boxcar lettered for the RGS with a Sunrise herald! It even retains a 3000-series number:
RGS_Box_1
RGS_Box_2
The caption claims the photo was taken in Durango in 1948. I'll be honest, I've seen one or two D&RGW 3000-series boxcars with the RGS sunrise herald in model form before and always assumed I was seeing "modeler's license." But here it is for real!
Does anyone know any more about this car? Were there more? Thanks!
