Athearn Genesis HO Scale EMD SD90MAC Diesel Locomotive

Bring the massive power and unmistakable appearance of one of EMD's largest modern diesel locomotives to your railroad with the Athearn Genesis HO Scale EMD SD90MAC. Combining extensive prototype-specific detailing with the smooth, powerful performance of Athearn's Genesis drivetrain, the SD90MAC is built for modelers looking to recreate heavy mainline freight operations in HO scale.

EMD SD90MAC Prototype

EMD developed the SD90MAC during the 1990s as a new generation of high-horsepower, AC-traction diesel locomotives. Early examples were delivered with EMD's proven 710G prime mover while the new 265H engine was under development. These 710G-powered locomotives, commonly associated with the SD9043MAC designation, became an important part of heavy freight operations and continued serving through multiple owners and paint schemes.

The locomotive's enormous six-axle frame, wide North American safety cab and distinctive modern EMD styling make the SD90MAC an imposing addition to contemporary HO scale freight trains.

Genesis Drivetrain & Performance

Athearn Genesis locomotives are engineered for smooth and dependable operation. The SD90MAC features a precision drivetrain with a 5-pole skew-wound motor, precision-machined flywheels and all-wheel drive. All-wheel electrical pickup helps maintain reliable performance through switches, crossovers and demanding operating sessions, while the heavy die-cast frame provides the weight and traction needed for long HO scale freight trains.

DCC & Sound Options

Depending on the individual model and SKU, Athearn Genesis SD90MAC locomotives may be offered in DCC-ready or factory DCC and sound-equipped versions. Always refer to the individual product title and specifications to determine the electronics configuration of the locomotive being purchased.

DCC-ready models feature Quick Plug technology with a 21-pin NEM connector, providing a convenient foundation for modelers who prefer to select and install their own compatible decoder.

Factory DCC and sound-equipped models feature a SoundTraxx Tsunami2 DCC sound decoder and dual cube speakers. These versions provide digital sound, lighting control, programmable operating functions and refined slow-speed performance for realistic locomotive operation.

Prototype-Specific Genesis Detail

Athearn Genesis SD90MAC models incorporate road-name and road-number-specific details where appropriate. Individual locomotives may feature differences in lighting arrangements, number boards, ditch lights, snowplows, pilots, air horns, nose details and other appliances to more accurately represent the prototype being modeled.

This attention to prototype variation makes the Genesis SD90MAC an excellent choice for model railroaders assembling a railroad-specific locomotive roster as well as collectors seeking accurately configured examples of these massive EMD diesels.
