locale=North America, AustraliaThe GE 44-ton switcher is a 4-axle diesel locomotive built by General Electric between 1940 and 1956. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the efficiencies the new diesel locomotives offered compared to their steam counterparts, reduced labour intensity. In the 1940s, the steam to diesel transition was in its infancy in North America, and railroad unions were trying to protect the locomotive fireman jobs that were redundant with diesel units. One measure taken to this end was a stipulation that locomotives weighing convert|90000|lb|kg or more required a fireman in addition to an engineer. The 44-ton locomotive was born to skirt this requirement. Other manufacturers also built 44-ton switchers of center-cab configuration. 348 examples of this locomotive were built for North American railroads. Many remain in either in service, or in museums.

Prime mover options

The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 convert|180|hp|kW|0|lk=on engines, but three other engines types were used. Nine were built with a pair of Hercules DFXD engines, and were sold to Chattanooga Traction (2) and Missouri Pacific Railroad and its subsidiaries (7). Ten were built with a pair of the slightly more powerful Buda 6DH1742, rated at convert|200|hp|kW each. The last four locomotives built had Caterpillar D342 engines, and were sold to Canadian National Railways (3) and the Danville and Mount Morris Railroad (1).

Australia

Forty-seven locomotives were bought by the US Military, and four of them were exported to Australia. All saw service on the New South Wales Government Railways as the 79 class, before two of them were sold to Commonwealth Railways, becoming the DE class.

Preserved Examples

United States
* The Western Pacific Railroad Museum at Portola, California is the home of Quincy Railroad 3. This 44 ton engine replaced steam power on this shortline railroad. The WPRM is also home to Quincy 4, an Alco S1 switcher that replaced QRR 3.
* The Lake Superior and Mississippi Railroad in Duluth, MN uses a loco formally used at the Lac de Flambeau paper mill.
* The California State Railroad Museum in Old Sacramento runs the Sacramento Southern Railroad Number 1240, formerly the U.S. Air Force Number 1240 out of McLellan Air Force Base.
