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.

The GE (General Electric) ES44DC is a type of six-axle, 4,400hp diesel locomotive built from 2004 to 2010 (first introduced in 2003) with a total of at least 1,368 built. The model is part of GE's "Evolution Series" (otherwise known as a "GEVO"). A typical CSX ES44DC (now classified as …

2024年12月31日 · Today, all new road-switchers produced by GE-successor Wabtec Freight, feature AC traction. BNSF ES44DC #7413 leads a westbound intermodal freight down the 2.2% grade of Cajon Pass. Loyd Lowry photo. With the release of the AC4400CW in 1993, General Electric forever changed how main line locomotives were built.

ES44DCi/ES44ACi. 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.

The ES44DCi is a special order locomotive for Rio Tinto. It is a GE ES44DC with increased cooling capacity that is built on a 76' frame, which is the same length as the AC6000CW frame but several feet longer than the normal ES44DC frame.

Rio Tinto's no 8127 ES44DCi, a modern and technologically advanced loco of 4400 horse power General Electric units, leads an empty train uphill. ES44DCi 8131, built by General Electric as #59134, heading an iron ore train through the bush land of Millstream. Rio Tinto class ES44DCi 8131, C44-9W 7094 (ex Hamersley) and ES44DCi 8186.

For customers who still preferred DC powered locos, the 4,000 hp ES40DC and 4,400 hp ES44DC were offered. For Australian customers, the ES44ACi and ES44DCi were offered, which have better cooling. For the EPA Tier 2 emissions standard, GE developed the new Evolution Series engine, also known as “GEVO”. By far the most successful variant, with al.

The ES44DCi model provided greater fuel efficiency and lower emissions than earlier locomotives, as well as larger cooling systems to cope with the hot temperatures experienced in the Pilbara. These units were obtained to meet the growing demand for iron ore and an expanding railway network in the Pilbara region of Western Australia.

These units are ES44DCi's. The increase in radiator length is to accommodate massive cooling needs in the Australian Outback. CN was the last customer to order D.C. traction locomotives.
