Sunny Saturday Sand Dump | On a humid Saturday, July 1, 2023 morning, an Arkansas & Missouri Railroad sand train prepares to dump ten carloads at Eagle Redi-Mix Concrete in Rogers, AR. Five cars are left on the main to begin with, as the industry track is not long enough to dump all ten in one move. Powering the train are A&M Alco C420s 56 and 57 - a sister pair origninally built in 1966 as Lehigh & Hudson River Railway 25 and 26.
