Cattle and livestock were important traffic on every U.S. and Canadian railroad. Federal laws mandated that animals be rested and fed en route, so stock pens like this could be found in yards as well as small town. Huge stockyards, covering several acres, could be found in big cities, and packing plants needed pens to hold livestock. With its modular design, this kit builds everything from the small town loading pen to the big city stockyard. Includes detailed parts for two pens with loading chutes, which align with 40' stock cars, plus a lean-to for shelter or feeding. 10.5 X 13" (26-1/5 X 32-1/2cm)
