Conrail ordered 100 GP15-1s in 1979. Intended for secondary and branch line trains, they featured snowplows on both ends for bidirectional use. Signal boxes were also standard equipment, allowing the GP15s to be used for road service when required. Most survived till the end of Conrail, and were split between NS and CSX- frequently while still in their Conrail blue paint.
