Good topic. Growing up in the 80's I was babysat by my grandma who lived a block from the Union Pacific main line in Marysville, Ks. I would sneak down and watch trains in the yard and a few times I was escorted back to her house by observant railroaders after I was found standing a little close to a siding. Interest in the Mopac sparked due to it being the line that ran through my hometown of Waterville. Through family history I learned that some ancestors took the train to the end of the line at Waterville circa 1870's and homesteaded up by Hanover, Ks. I met Milford Godsey who was a retired station Agent at Waterville and my interest in the Mopac was solidified.
