This is a MTH 33-2022-3 SD90-Mac Diesel Engine (Non-powered) Caterpillar. Serious efforts to use AC (Alternating Current) diesel-electric engines began when General Motors introduced its 4000-horsepower SD-60MAC in 1991-92. While the AC power increases an engine’s adhesion, allowing it to start far heavier trains than a DC-powered locomotive of the same horsepower, the heavier load prevents AC-powered engines from reaching track speed. To solve that problem, locomotive builders have raced to design and deliver AC engines with ever-larger horsepower. SD90-MAC’s use a whopping 6000 horsepower to power their freight down the rails. Features include: Intricately Detailed ABS Body, Colorful Paint Scheme, (2) Operating Metal Couplers, Metal Chassis, Metal Handrails and Decorative Horn, Metal Wheels, Axles and Gears, (2) Precision Flywheel Equipped Motors, Operating Horn.
