Prior to the appearance of diesel power passenger traffic on the Illinois Central was usually in the capable hands of Pacific types like No. 1165, shown here in Chicago on August 5, 1948. She belonged to a class of forty locomotives outshopped by American Locomotive Company's Brooks works in 1916 and 1918, this example being part of the latter group; they and others erected later are sometimes grouped into a "class 1139" following rebuilding in the IC's Paducah shops. They had a driver diameter of 75½ inches and cylinder dimensions of 26x28-inches. When rebuilt during World War II their boiler pressure was raised from 190 to 215 p.s.i., yielding a tractive effort of 45,816 pounds. With a locomotive weight of 280,000 pounds they had a grate area of 55 square feet, 3625 square feet of evaporative heating surface, and 826 square feet of superheating surface. No. 1165 was retired and scrapped in 1949. The photo is the work of D. N. Eldridge and was acquired from an eBay vendor.
