The 44 engines of the Erie's K-4 class of 4-6-2s came from several builders in 1913. No. 2719 represents the group in this photo from the Wayne Koch collection — photographer, date and location unidentified. With 69-inch drivers, they had 210 p.s.i. of boiler pressure and cylinder specifications of 25x28 inches. They weighed 287,000 pounds and developed 45,272 pounds of tractive effort. Their grate area totaled 58 square feet, and they had 4015 square feet of evaporative heating surface and a superheating surface of 873 square feet. Unlike the K-4-A class, their drivers apparently were never enlarged to make them more suitable for passenger service; the larger footboard on the pilot suggests they remained freight locomotives.
