The Pere Marquette's class MK-2 2-8-2s came from American Locomotive Company in 1927, erected consistent with the USRA light Mikado design. They had cylinder dimensions of 26x30 inches, a boiler pressure of 200 p.s.i., and a driver diameter of 63 inches. Exerting a tractive effort of 54,724 pounds, they weighed 311,000 pounds. Evaporative heating surface was 3467 square feet, superheating surface 992 square feet, and grate area nearly 67 square feet. No. 1050, the final member of the class, rests at an unidentified terminal in this photo, purchased on eBay, for which no information is available. All members of the MK-2 class were scrapped in 1952.
