Superdetailed Athearn ES44AC models a 21st century workhorse in HO scale

摘要

A mainstay of today's main lines, the General Electric Evolution Series (GEVO) ES44AC is now available as part of the Athearn Genesis line of superdetailed HO scale locomotives. We tested a BNSF and a Union Pacific version. Both models feature prototype-specific detailing and a SoundTraxx Digital Command Control (DCC) sound decoder. Prototype. The General Electric ES44AC (Evolution Series 4,400 hp with alternating-current traction motors) entered production in 2005. Like its main competitor, the Electro-Motive Diesel SD70ACe, the GE ES44AC meets the United States Environmental Protection Agency's strict Tier Ⅱ emissions regulations. The heart of the locomotive is its 4,400 hp GEVO-12 diesel engine that produces as much horsepower as the 16-cylinder diesel engine in the GEVO's predecessor, the AC4400CW. The GEVO engine also has greater fuel economy and lower emissions.
