Orginally, the Monon purchased four F-3B units, nos. 61C, 62C, 63C, and 64C. The 64C was wrecked at Ash Grove on 6/3/47 and scrapped. A replacement unit, 64C 2nd arrived in 9/47. Following the Ash Grove wreck, the Monon acquired the EMD F-3 A-B-A Demonstrator set number 754. The A units became 85A & 85B while the B-unit became 65C. The 65C was the only Monon B-unit equipped with a steam generator for passenger service. All of the F-3 B-units were renumbered into the 300 series in October, 1962.
