| One of today's most powerful locomotives, the SD90/43MAC is one of the heaviest and longest single diesel locomotives in the world.
The model is a replica of the 4,300 horsepower "SD90/43MAC," which is equipped with the revolutionary radial truck, the EMD HTCR-II, capable of reducing the angle of wear between wheels and rail.
The models include a powerful five-pole motor with dual brass flywheels, white LED headlights, semi-automatic knuckle couplers, MU hoses, DCC socket, ditch lights, 45" scale wheels, and separate windshield wipers. Some detail parts require installation by the modeler.
While the models may physically be capable of operating on a 18" radius curve, it is recommended they be run on curves no smaller than 22" radius. Larger radius curves will yield better operation of these massive models.
