The units were delivered with 62:15 gearing with a rated Maximum Authorized Speed of 70 (overspeed set at 72). Within 12 to 18 months, all were regared to 60:17 with a rated Maximum Authorized Speed of 79 (overspeed set at 83), do to their inability to maintain the schedules on trackage where 79 MPH operation was permitted. All but 3201 and 3207 were regeared back to 62:15 after they were assigned to commute service starting in late 1974. 3201 and 3207 retained their high-speed gearing due to their occasional used on company specials that operated on 79 MPH trackage. Like their other 8 sisters, they were often used in freight service on weekends and long holidays.
