Although the SD90MAC has been produced in HO before, previous releases modeled the early 4,300 hp version. This new model from Athearn Trains marks the first time HO scale modelers can get an accurate model of the later 6,000 hp version, the SD90MAC-H Phase II.
Part of the new Athearn Genesis 2.0 series, this high-horsepower heavy hauler is decked out with prototype-specific details. It’s also available factory-equipped with a SoundTraxx Tsunami2 dual-mode decoder and twin cube-style speaker sound system that operates on both Digital Command Control (DCC) and direct-current (DC) layouts.
