Models
Currently three different Evolution Series models have been produced. They are all six axle locomotives and have the wheel arrangement C-C (AAR classification) or Co'Co' (UIC classification).
ES40DC
The ES40DC (Evolution Series 4000 hp DC traction) replaces the former Dash 9-40CW model in GE's range and, like the former model, has been delivered exclusively to Norfolk Southern. NS appears to prefer a slightly lower-rated locomotive which uses less fuel while producing the same tractive effort but also reduces wear on the engine components than higher horsepower models used by other railroads.
ES44DC
The ES44DC (Evolution Series 4400 hp DC traction) replaces the former Dash 9-44CW model in GE's range. Primary users are BNSF Railway, CSX Transportation and Canadian National. Pilbara Iron in Australia is receiving a lengthened, international version designated ES44DCi. The extra length is being used for a longer radiator to increase cooling capacity in the Australian desert.
ES44AC
The ES44AC (Evolution Series 4400 hp AC traction) replaces the former AC4400CW model in GE's range. These locomotives have been ordered by Union Pacific Railroad (who refers to these locomotives as the C45ACCTE) BNSF Railway, Kansas City Southern, Kansas City Southern de Mexico, Ferromex, and Canadian Pacific. Iowa Interstate Railroad ordered 12 ES44ACs in April, 2008 to be delivered by October 1, 2008 to handle an expected traffic growth of 25%-30%, resulting from new ethanol plants coming on line.
CSX began receiving delivery of 200 ES44ACs (referred to by CSX as ES44AH locomotives) for 2007-2008 in December 2007. While primarily intended for unit coal service, they will likely also see general service. The 'H' in "AH" is symbolic of the heavier than standard configuration with High Tractive Effort software. CSX's low speed, high tractive effort software is very similar to that used on Union Pacific Railroad units. Additionally these units will be equipped with software to operate in DPU or "Distributed Power Unit Mode" as remote control helpers.
Also, CEMEX Cement took delivery of one ES44AC, number 81, in March 2008.
Identification and spotting features
The Evolution Series locomotives very much resemble the previous Dash 9 and AC series safety cab models in superficial appearance. Both AC and DC models have the large cabinet behind the crew compartment on the left-hand side which on the AC models houses the traction inverters. The previous Dash 9 models had a much smaller cabinet here than the AC models did. It is thus difficult to distinguish the DC and AC versions of the Evolution Series.
Previous designs had substantial space between the exhaust stack and the radiator "wings", and this is lacking on the Evolution Series.
The radiator section is significantly longer than previous designs, and extends forward towards the exhaust stack. As on the AC6000CW, it overhangs at the rear. The sloped underside has two sections with different slope angles, unlike the single previous angle. The front end on top has a raised 'hump' - this area houses the air-to-air heat exchanger and water-to-air heat exchanger fitted to these locomotives to improve emissions.
Overall length appears to be shorter, but is the same, and the fuel tanks are identical. The standard truck is the HiAd, but a Steerable Truck is an option.

Export sales
In October 2005 China Railways ordered 300 Evolution Series locomotives from GE Transportation Systems and Qishuyan Locomotive and Rolling Stock Works for delivery in 2008-2009. Two have been built at Erie, Pennsylvania, the rest will be assembled by Qishuyan at Changzhou.[1]
On September 28, 2006, Kazakhstan Temir Zholy, the national railway of Kazakhstan, signed a purchase agreement with GE Transportation Systems ordering 310 Evolution Series locomotives. The order represents the first export of the locomotive to a railroad company outside of North America. The first ten of these locomotives will be built in GE's Erie, Pennsylvania, plant while the remaining 300 will be built at a new plant in Pavlodar, Kazakhstan. Delivery is expected between 2008 and 2012. The locomotives will be built with dual cabs and will become the first diesel-electric locomotives with AC traction motors to operate in the Commonwealth of Independent States.[2]
