The Frisco received the ten Consolidations of class 1281 from American Locomotive Company's Brooks works in 1910. They weighed 227,200 pounds and mustered 49,251 pounds of tractive effort. Having cylinder dimensions of 26x30 inches, they rolled on 63-inch drivers and eventually carried 180 p.s.i. of boiler pressure. They had a 50-square-foot grate area; after being superheated with 578 square feet of superheating surface they had 2541 square feet of evaporative heating surface. No. 1292 appears here at St. Louis in June, 1939 in a photo provided by Donna Harrison-Rodeghiero; the photographer is unknown.
