The successors to GE's Dash-9 series, the Evolution Series or "GEVOs" are aimed at giving railroads high horsepower units that can meet the Tier 2 emission requirements and burn less fuel. The key to these improvements is the change from the 16-cylinder HDL engine to the 12-cylinder EVO. The cabs and frames are based on those of the Dash-9s, but as the EVO engines are shorter, the hood design is different, and the radiator "wings" are much more striking in appearance.
ES44DC
CSX is a major user of the ES44DC, which replaced the Dash 9-44CW in the GE catalog. An initial block of just over 300 locomotives is being followed up by an order for 100 more. 5461 is shown here westbound out of Pittsburgh, PA.
CSX 5441 leading an ex-Conrail C40-8W.
CSX 5235 leading a Dash-8, this time eastbound.
CSX ES44DC 5208 leads a smoking CSX 97 (AC4400CW) and GP38-2 2668 eastbound.
CSX 5372 leading AC4400CW 585 and another unit eastbound. Note the difference in radiator wing design between the GEVO and the trailing older GEs.
CSX 5387 leading CSX 7891, a C40-8W
