The Rutland Railroad's four Ten-Wheelers of class F-2k came from ALCo's Schenectady Works in 1913 with saturated boilers and Stephenson valve gears, but the Rutland quickly rebuilt them with superheating and Walschaerts gear, changing their classification from F-2h to F-2k. Additionally, their original 22-inch cylinder diameter was bored out to 22½ inches, with a stroke of 26 inches. With 69-inch drivers, they mustered 200 p.s.i. of boiler pressure, developed 32,429 pounds of tractive effort, and weighed 204,600 pounds. Their grate area measured 55 square feet and after rebuilding they had 2627 square feet of evaporative heating surface and 537 square feet of superheating surface. No. 71 of the class appears at Rutland on May 1, 1950, in a photo by an unspecified photographer provided by Carl Weber. Retirement for this engine came the year after this photo was taken.
