These huge engines were named the Challenger Simple Articulated, or CSA-1, class. The railroad received 25 near copies, classified as CSA-2, the following year.\u003c\/p\u003e\n\u003cp\u003eUnlike compound Mallet engines that crawled along with drag freights, the Challengers had two sets of high- pressure cylinders and could safely reach passenger train speeds. The mammoth locomotives also had a heavy-duty starting tractive effort of 97,400 pounds.\u003c\/p\u003e\n\u003cp\u003eOriginally constructed to haul fast freight up the famous Wasatch grade, the CSA-1 and -2 Challengers would hold a variety of assignments over their long careers- including passenger service. Depending upon their operating territory, they burned either coal or oil, and some locos were converted back- and-forth several times.\u003c\/p\u003e\n\u003cp\u003eFEATURES:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e#3820 Class CSA-2, Worthington feedwater heater, large sand dome, covered vertical bar pilot, walkway “hump”, no steam pipe to front cylinders, blackened metal side rods, satin paint finish, oil burner.
