The power difference is due to different settings of the diesel engine's governor. Mechanically it is the same engine. NS choose to rate thiers are 4000hp to (hopefully) increase life and reduce fuel consumption. But NS has been (maybe done by now) at various horsepower levels from less than 4000hp to over 4500hp, to try to determine which makes most sense overall for them.
