The Wabash's high-stepping Atlantic types of class E-4 featured 80-inch-diameter drivers. They had 21x28-inch cylinders and 210 p.s.i. of boiler pressure, and exerted 27,551 pounds of tractive force. Their modest proportions gave them only 45 square feet of grate area. Although originally unsuperheated, a rebuilding gave them 2365 square feet of evaporative heating surface and 510 square feet of superheater surface. In this view scanned from a print in the collection of Wayne Koch, No. 606 poses at an unidentified location probably during the early 1930s. The photographer's identity is also unknown.
