PROTOTYPE SPECIFIC INFORMATION
Introduced in 1995, the EMD SD90MAC was intended to become
that builder’s most-powerful single-engine diesel locomotive.
The new locomotive was to use EMD’s newly-developed 265H
prime mover, featuring 6000 horsepower. However, this engine
was experiencing technical problems in development, which led
to the first groups of locomotives being delivered with the EMD
710G prime mover of 4300 horsepower (the intent being to retrofit
these with the more-powerful 265H at a later date). Ironically, the
technical problems with the 265H were never fully resolved, and no
conversions were done. The 710G-engined SD90MACs outlasted
their later 265H cousins in service by a wide margin, with some
units only recently having been retired or sold by Union Pacific,
and other railroads choosing to rebuild them for continued service.
The Athearn Genesis SD90MAC features all of the cutting-edge
detail and operational features that are expected by discerning
modelers: Working number boards and ground lights, see-through
steps, numerous separately-applied details on the body and
underframe, and a heavy die-cast frame for massive pulling power.
