The GP-40 was the 3000 horsepower successor to the late 1960s-era GP-38, best characterized by the three full size radiator fans on the rear of the roof. 

The GP40-2 was the successor to the popular EMD GP-40. The GP-40-2 had mostly internal changes but several outside details varied as well. Such details include bolted down battery box covers and a roof that extends slightly beyond the rear of the cab.
