Edit 2/25/2024: Note the two step taper from the hood top into the cab front. This is a characteristic of the first four phases of NW2 production. Frisco's first 10 NW2 units, SLSF 250-259,were phase IV units with this characteristic. Its last six NW2 units, SLSF 260-265, were phase V units. These units has a single continuous slope taper from the hood top to the front of the locomotive cab. MKD
