In 1936 the Louisiana & Arkansas, a subsidiary of the Kansas City Southern, received five class M-22 Mikado type locomotives from Lima Locomotive Works. Weighing 301,000 pounds, these 2-8-2s developed 54,800 pounds of tractive effort, plus 16,500 pounds supplied by a booster installed on the front tender truck. These clean-lined locomotives had the 63-inch drivers usual for their type, a 240-p.s.i. boiler pressure, and cylinders of 23x32 inches. With 3986 square feet of evaporatibve heating surface and 1016 square feet of superheating surface, they had a grate area of 60.1 square feet. The Lima builder's photo comes from the 1951 edition of World Railways.
