The production version we have chosen to recreate is the 4,300 horsepower "SD90/43MAC". It is equipped with the revolutionary radial truck, the EMD HTCR-II, capable of reducing the angle of wear between wheels and rail.



Model Features -

This production of our HO-Scale SD90/43MAC includes one new roadname and one new paint scheme for our popular model. All models will be equipped with our 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 pieces require hobbyist installation. 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. " >

Prototype Information -

The SD90/43MAC is one of today’s most powerful locomotives, seen throughout North America on Class I mainline railroads, weighing in at more than 400,000 pounds. With a length in excess of 80 feet, the SD90/43MAC is one of the heaviest and longest single diesel locomotive in the world.

The SD80/90MAC series was introduced by EMD in late 1995. To date, there have been three production "versions" of the SD90MAC. Union Pacific, by far, operates the largest fleet of SD90MAC units. They have even applied different paint schemes to these units.
