The Evolution Series is a line of diesel locomotives built by GE Transportation Systems (now owned by Wabtec), initially designed to meet the U.S. EPA's Tier 2 locomotive emissions standards that took effect in 2005. The line is the direct successor to the GE Dash 9 Series. The first pre-production units were built in 2003. Evolution Series locomotives are equipped with either AC or DC traction motors, depending on the customer's preference. All are powered by the GE GEVO engine.[4]

The Evolution Series was named as one of the "10 Locomotives That Changed Railroading" by Trains Magazine and was the only locomotive series introduced after 1972 to be included in that list.[5]

The Evolution Series locomotives are some of the best-selling and most successful freight locomotives in United States history.

These locomotives are equipped with Nathan Airchime K5HL horns, with the reversed 2 configuration, making a K5HLR2. The horns are mounted backwards with the 2 bell only facing forward and the 4 bells facing back. All of the locomotives use these horns, except for the ET23DCM and international locomotives.


Currently, six different Evolution Series models (seven including rebuilds), have been produced for the North American market. They are all six-axle locomotives and have AAR wheel arrangement C-C (UIC classification Co′Co′), except for the ES44C4 and ET44C4 which uses the AAR A1A-A1A wheel arrangement and the meter-gauge version developed for the Brazilian network ES43BBi which is AAR B-B-B-B.

ES40DC (2004–2008)

NS ES40DC No. 7698

The ES40DC (Evolution Series, 4,000 hp, DC traction) replaced the Dash 9-40CW model in the General Electric catalogue and, like the former model, was delivered exclusively to Norfolk Southern Railway. ES44DCs owned by CSX Transportation were also given this designation in 2009 after being de-rated to 4,000 hp (3,000 kW). However, high-horsepower demand on Norfolk Southern made a mandatory repowering of several ES40DC engines into their former ES44DC power.[6]

ES44DC (2005–2010)

CSX ES44DC No. 5442

The ES44DC (Evolution Series, 4,400 hp, DC traction) replaced the Dash 9-44CW model in the General Electric catalogue. Primary users are BNSF Railway, CSX Transportation, and Canadian National Railway. Pilbara Iron in Australia ordered a lengthened, international version designated ES44DCi. The extra length is used for a larger radiator to increase cooling capacity in the Australian outback.

ES44AC (2003–present)

CN EF-644p No. 2869
Citirail (CREX) ES44AC No. 1203
UP C45ACCTE No. 7767

The ES44AC (Evolution Series, 4,400 hp, AC traction) replaced the AC4400CW model in the General Electric catalogue. These locomotives have been ordered by every Class I railroad in North America: Union Pacific Railroad (who refers to these locomotives as the C45ACCTE), BNSF Railway, CSX Transportation, Norfolk Southern Railway, Ferromex, CPKC Railway, and Canadian National Railway.

Union Pacific also bought the heavy ballasted variation of this model, the ES44AH, and refers to it as the C45AH. UP also uses this designation to refer to their ET44AH units.

CSX Transportation has bought these locomotives and they were always heavy ballasted, so they called these the ES44AH. The first set was 700-999, which was built from 2007-2011. Beginning 2023, CSX has repainted and renumbered the 3000 series locomotives to heritage units. The first heritage, 1827, was painted into Baltimore & Ohio and renumbered from 3059 on May 11, 2023.

BNSF Railway has bought 25 ES44AC locomotives in 2023, and they are all classified as ES44ACH. They were built between August and September of 2023 and were built concurrently with the ET44ACH. The numbers were 3282-3306, which officially ended the production of the ES44C4 in 2020. These units are Tier 4 credit units. In 2024, BNSF has bought 25 more ES44ACH locomotives, which are numbered from 3307-3331. These locomotives weigh 436,320 lbs.

ES44C4 (2009–2020)

BNSF ES44C4 No. 8013

The ES44C4 (Evolution Series, 4,400 hp, C to denote 3 axles per truck, 4 traction motors) was introduced in 2009. While similar to the ES44AC, the ES44C4 has two traction motors per truck, instead of the conventional three such as on the ES44AC. No ES44C4s with DC traction were built. The center axle of each truck is unpowered, giving an A1A-A1A wheel arrangement. BNSF Railway is the launch customer for this model, ordering an initial batch of 25 units numbered 6600–6624.[7] The ES44C4 was initially only built for BNSF. The 4200s and units 7921-7999 are certified as Tier 4 Credit units, while the others are Tier 2 or Tier 3. On 30 January 2014 Florida East Coast Railway announced that they would buy 24 ES44C4s, to be numbered 800–823, for heavy haul service and intermodal traffic. All were delivered by the end of 2014, in order to beat the EPA's deadline on exhaust-emissions standards for new-built Tier 3 locomotives.

A feature of these units is a variable traction control system in their computer systems. One of the differences between an ES44AC and an ES44C4 is the air cylinders and linkages on the truck sideframes of the ES44C4; these are part of the traction control system. Every time a variation in grade, traction, or wheel slip occurs, the computer adjusts the pressure in these cylinders to maintain sufficient adhesion, by varying the weight on the drive axles.[8][9]


Wabtec ES44ACi No. 2542
Rio Tinto ES44DCi No. 8181

The ES44DCi (Evolution Series, 4400 horsepower, DC traction, international version) was built for the Rio Tinto railway in Australia. The ES44ACi was built for the Roy Hill and Rio Tinto Group.

Rio Tinto's units can be remotely driven, meaning nobody has to be in the cab as they can be controlled from a control center.[10]

The ES44ACi/DCi is essentially an ES44AC/DC in a GE AC6000CW's body, with the radiator at the end protruding out over the rear deck in the same way the AC6000CW does. The locomotive's large radiator allows it to handle the Australian outback's extreme temperatures.

Roy Hill has ordered 21 ES44ACi locomotives, and is currently in possession of all 21 locomotives (numbered 1001 "Ginny"-1021). Rio Tinto ordered 100 ES44DCi locomotives and has all 100 (numbered 8100–8199) and 21 ES44ACi locomotives (numbered 9100–9120) and more are on order.

Ferromex also acquired 50 ES44ACi. As the construction of these locomotives was subsequent to the new environmental laws of the US, GE cataloged them only as ES44ACi, although in the external technical specifications of the locomotives say ES44AC). These locomotives can no longer reenter the US operating.

In Brazil, the Rumo, Suzano and MRS Logística railways purchased 25 units, manufactured at Wabtec of Brazil with broad-gauge trucks.[11]

ET44AC/ET44C4 (2012–present)

Union Pacific ET44AC (C45AH) No. 2668
BNSF ET44C4 No. 3680

The ET44AC (Evolution Series Tier 4, 4,400 hp, AC traction) replaces the ES44AC model. These locomotives have been ordered by most of the Class I railroads in North America, including Union Pacific, CSX Transportation, Norfolk Southern, Canadian National Railway, Kansas City Southern and BNSF Railway. BNSF Railway also ordered similar ET44C4 locomotives, which have a dynamic weight management system instead of a traction motor on the middle axle of each truck. UP and CSX designate their ET44ACs as ET44AH although UP calls these C45AH, and BNSF calling them ET44ACH as their locomotives are heavy-ballasted.

BNSF Railway has bought 25 ET44AC locomotives in 2023, and they are all classified as ET44ACH. They were built between May and September of 2023 and were built concurrently with the ES44ACH. The numbers were 3650-3674, which officially ended the production of the ET44C4 in 2020. The first unit, which was 3650, was the first one to be built in May 2023. These units follows the Tier 4 standards. In 2024, BNSF has bought 25 more ET44ACH locomotives, which are numbered from 3625-3649. These locomotives weigh 436,320 lbs.

ET23DCM (2023–present)

CSX ET23DCM No. 1718

The ET23DCM (Evolution Series Tier 4, 2350 hp, DC traction), sometimes called the SD23T4, is a modernized locomotive using EMD's SD40-2 platform and the Wabtec Inline 6-cylinder Tier 4 diesel engine. CSX Transportation ordered 15 of these locomotives, with most being built at their Huntington Heavy Repair Shop. Wabtec also built one locomotive as a demonstrator from ex-NS SD40-2 3259.

Identifying features

The Evolution Series locomotives are visually similar to the AC4400CW and GE Dash 9 Series, although small differences are evident. The most noticeable difference is the radiator section at the rear of the locomotive is larger to accommodate the GEVO's air-to-air intercoolers. As with the AC6000CW, the radiators project beyond the end of the hood. On the ES44ACi and ES44DCi models, the radiator extends in the same way as the AC6000CW, protruding out over the rear deck. For the other Evolution Series locomotives, the radiator does not protrude completely over the rear deck, but rather sits nearly flush with the rear of the engine hood. Unlike previous GE locomotives, the grills under the radiator are at two different angles. The increase in radiator size is due to the necessity for greater cooling capacity in the locomotive in order to reduce emissions. The other major difference between the Evolution Series and earlier models is the vents below the radiators, which are larger than those on previous GE locomotives.[12] Also, all Evolution Series units have air conditioners mounted below the cab on the conductor's side.

Licensed production


In 2002, GE and UGL launched the Evolution Series locomotive, and in 2009, continued their partnership for another 10 years for UGL to distribute and sell GE locomotives in Australia.[40]


In November 2015, it was announced Indian Railways and GE would engage in a 11-year joint venture in which GE would hold a majority stake of 74%, to provide a mix of 1,000 diesel locomotives of type ES43ACmi[41] which are 4,500 horsepower and type ES57ACi[42] which are 6,000 horsepower each. Indian Railways designated these 1,676 mm (broad gauge) locomotives as the WDG-4G class and WDG-6G class respectively. General Electric has invested ₹2,052 crore (US$305 million) for its construction. In the $2.6 Billion deal, Indian Railways would purchase 1,000 goods locomotives a year for ten years beginning in 2017; the locomotives would be modified versions of the GE Evolution series.[1] Diesel Locomotive Factory, Marhowrah was built by GE for the manufacture of the locomotives.[2]

South Africa

TFR Class No. 44-005

Transnet Engineering in South Africa has a license to manufacture 233 4,200 hp (3,100 kW) 3 ft 6 in (1,067 mm) Cape gauge ES40ACi locomotives for Transnet Freight Rail, with core components including GEVO-12 engines supplied from the United States.[43]

The first six of these Class 44-000 locomotives were built in Erie, Pennsylvania, in April and July 2015. In October 2015, the first of the 227 South African-built locomotives was nearing completion at Transnet Engineering's Koedoespoort shops in Pretoria.[44]
