Over the last year, model railroader Andrew Dodge has gotten a lot done on his O fine scale (Proto:48) Colorado Midland. Read this article from Model Railroad Planning 2013 to learn how Andrew designed this 28 x 28-foot model railroad set in 1897 in western Colorado.
Hated to see Andrew tear down his On3 DSP&P line but the new Colorado Midland is an excellent replacement. Looking forward to my first visit to see it in person.
