Athearn G31550 HO AC4400CW Locomotive – CSX #1

CSX purchased more AC4400CWs than any other railroad, spanning almost the entire production period. This includes three of the first six produced
which have distinctive spotting features compared to all other units. A lightning bolt graphic was applied under the road number making these easy to
identify as AC traction motors. Unique to CSX, all these units are equipped with hooks to carry a length of chain under the walkway.

PROTOTYPE SPECIFIC INFORMATION
Introduced by GE in 1993 and built until 2004, when it was replaced
by the Evolution Series Tier II compliant model, the AC4400CW is a
staple of modern railroading. 2,834 examples were built with many
still plying the rails in their as delivered configurations or as rebuilt
variations. Many Class 1, regional, and foreign railroads purchased the
AC4400CWs. Ownership spanned the North American Continent and
with their long lives, have seen numerous paint scheme variations and
ownership changes through the years. The AC4400CW went through
a large number of changes during its production. Some are easily
noticeable; early units being delivered with GE’s Hi-Adhesion Trucks,
while later units that had the option for newly developed GE Steerable
Truck. Other details are smaller and takes a careful eye to see; the
addition of a door stop, how the step wells are reinforced, or the number
and positioning of panels and doors.
Athearn has captured all these details thorough research and precision
tooling to reproduce dozens of variations. The newly tooled Genesis
AC4400CW takes its reign as the new flagship model for Athearn.
