Source (C&O Power) doesn't give superheater area but the C & O Locomotive Diagram book from 1936 (supplied by Allen Stanley in May 2005) does.. Cylinder horsepower calclulated to be 3,102. Elesco feedwater heater on 2952 only.
Built by Alco's Brooks works for the Wabash (see separate entry), but were the property of the Chicago & Eastern Illinois when the C&O bought them during World War II. These were the heaviest of the C&O's Santa Fes; they had the highest factor of adhesion and the largest boilers.
