Chesapeake & Ohio 2-8-2 No. 1137 appears here at Columbus, Ohio, on April 24, 1938. She belonged to the "Chessie's" K-1 class that rolled off the erecting floor of ALCo's Richmond works between 1911 and 1914. Members of this class weighed between 322,500 and 325,500 pounds. Their grate area, supported by an inboard-journal trailing axle, totaled 67 square feet, and they had 4050 square feet of evaporative heating surface and 845 square feet of superheater surface. Although they sustained only 170 p.s.i. of boiler pressure, their cylinder dimensions of larger diameter than stroke (29x28 inches) and low 57-inch drivers contributed to a high tractive effort of 59,700 pounds. This photo is the work of Lamar M. Kelley of Elkhart, Indiana and came to us through the good offices of Tom Rock of Rock on Trains, Cleveland, Tennessee. No. 1137 is said to have been the last remaining member of the K-1 class, being retired in 1953.
