Actually I think we are both right.....Next time you are in the cab, zoom in on the builder plate just to the left of the forward (which would actually be PRR rear...another error) engineer's widow. It clearly says GP9 on it. Regardless, the engine clearly does not have a dynamic brake grid so it should not have a dynamic brake option (although it does). GP7s seem to have been use primarily by PRR in and around chicago....not on the mountainous Middle Division.
