This is the N Scale GE ES44AC GEVO and Mixed Freight Starter Set, Canadian National from Kato.
The ES (Evolution Series) of locomotives are built by GE Transportation Systems and designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. These Evolution Series locomotives are equipped with AC traction motors and are powered by a newly designed "GEVO-12" 12 cylinder engine that produces the same power as the 16 cylinder AC4400CW, but with fewer emissions and greater fuel economy. It also carries a redesigned air-to-air dual-fan heat exchanger, which gives it its distinct "oversized" radiator; a common spotting feature for these new locomotives.
