Atwood purchased two locomotives and most of the passenger and freight cars when the Bridgton and Saco River Railroad was dismantled in 1941. After World War II he acquired two former Monson Railroad locomotives and some surviving cars from the defunct Sandy River and Rangeley Lakes Railroad in Maine. This equipment ran on narrow gauge tracks, as opposed to the more common narrow gauge in the western United States. Atwood purchased the equipment for use on his cranberry plantation in South Carver. After the 1945 cranberry harvest, Atwood's employees built of track atop the levees around the cranberry bogs. Sand and supplies were hauled in to the bogs, and cranberries were transported to a "screen house" where they were dried and then sent to market. Atwood's neighbors were enchanted with the diminutive railroad. At first, Atwood offered rides for free. When the demand for rides soared, he charged a nickel a ride. Eventually the line became less of a working railroad and more of a tourist attraction.
