I am a model railroader as well. Currently I am building an HO scale layout depicting the St. Louis-San Francisco's Arthur Subdivision in Paris, Texas, circa 1975-1978. Besides the Frisco (of which I am a member of their historical society, and have more Frisco locomotives than I really need (don't tell the wife I said that!!)), I am including the Missouri Pacific and Santa Fe, as they also had a presence in Paris.
