Pat,
The choice is really up to you. It was pretty much mix and match between the 15s and 38s. They were both considered, equally, as low-horsepower 4-axle units by the power assignment folks. You used what was available. Any combination of these two locomotive types would be prototypical.
I liked the GP15-1 for switching because it was quick. The GP38-2 was slower, but it would pull like crazy. Each was better suited to certain jobs due to these characteristics, but that meant nothing to the mechanical department. They considered both models to be interchangeable.
