Between 1916 and 1926 the Wabash Railway rebuilt 23 class G-1 2-6-2s, originally ALCo and Baldwin products of 1906-1907, into class J-2 Pacific types at its Decatur, Illinois shops. No. 683, shown here in a photo supplied by Wayne Koch, was the first of the series constructed for use in the United States (a higher-numbered series was rebuilt for use in Canada). As redesigned, these engines had 70-inch drivers, a boiler pressure of 215 p.s.i., and cylinder dimensions of 23x28 inches. Their evaporative heating surface totaled 3190 square feet and their superheating surface 740 square feet, and they had 54 square feet of grate area. They developed 38,670 pounds of tractive effort and had a locomotive weight of 218,000 pounds. Since all or most Wabash passenger engines were eventually equipped with drop-coupler pilots, this photo dates from an earlier time; all members of the J-2 class were retired during 1947-1952. The photographer's name and photo location are unknown.
