The EMD GT22 Series were first introduced in 1972 after the rise in popularity of six axle locomotives. The GT series now carried a turbocharger that increased the horsepower depending on customer input. The GT series also utilized six axle HTC Trucks, which allowed the locomotive to haul heavier loads at slower speeds with minimal wheelslip.

The GT22C series also gave itself various individual designations depending on customer input. Standard suffixes after the model designation were either a 'U' or 'W' suffix to indicate the type of traction motors. A 'C' generally indicated six axle trucks but due to a six axle locomotive being too oversized for most second and third world countries, EMD developed the 'L' suffix to indicate the locomotive was constructed with a 'L'ightweight frame. EMD Dash 2 electronics also became a popular choice for the export railroads by the late 1970’s.

These designations could apply to any kind of export locomotive design of EMD or another licencee of EMD as long as the electrical & mechanical gear was left unaltered.

Overview

With the introduction of the 645 engine for export models in 1967, the model designation numbers changed by adding 10. To meet customer demands of a six axle version of the popular G12, EMD created the GR12 which was slightly longer and taller to accommodate the Type-C trucks.

EMD then designed the GT22 model to accommodate the HTC truck first found on the American EMD SD45X. Extending the carbody and increasing the fuel tank capacity, the GT22C series was introduced. Production spanned longer than the four axle G22 version, but with smaller orders.

Several models were introduced:

GT22CW

The EMD GT22CW was first appeared in 1972 and now carried a 'CW' suffix which indicated that this model had six axles (C) and traction motors that could fit from Standard Gauge rails to 5’ 6’’ (1,676 mt) gauge rails (W). Another new suffix introduced to this model was the 'T', which indicated the use of a turbocharger.

The GT22CW found most of its popularity in Argentina, while two unusual orders went to the Saudi Railways Organization in Saudi Arabia & the Société Nationale des Transports Ferroviaires of Algeria.

Production spanned from July 1972 to February 1988

GT22CU

The EMD GT22CU was first appeared in 1972. Designed mainly for the narrow gauge market, the GT22CU now carried a 'CU' suffix which indicated that this model had six axles (C) and traction motors that could fit from one meter to 5’ 6’’ gauge rails (U). Another new suffix introduced to this model was the 'T', which indicated the use of a turbocharger.

The GT22CU was purchased by the Ferrocarriles Argentinos & Estrada de Ferro Vitória a Minas from June 1972 to January 1980.

GT22CW-2

The EMD GT22CW-2 was first appeared in 1988 and now carried a 'CW' suffix which indicated that this model had six axles (C) and traction motors that could fit from Standard Gauge rails to 5’ 6’’ gauge rails (W). Another new suffix introduced to this model was the 'T', which indicated the use of a turbocharger. Finally, this model now carried the popular EMD Dash 2 electronics which improved it’s reliability.

The GT22CW-2 found most of its popularity in Argentina and even after the breakup of Ferrocarriles Argentinos, did the successors of that company continued to purchase more GT22CW-2s.

Production spanned from March 1988 to December 1997.

GT22HW-2

Main article: EMD GT22HW

An unusual departure from the standard/common production of the GT22 Series featured a custom model exclusively built for Yugoslavia due to economic crises after the 1970‘s as well as an increase in unreliable locomotives. Designated GT22HW-2, this multipurpose compact locomotive was introduced with a turbocharger (T), Head End Power (H) and EMD Dash 2 Electronics (-2); but due to it’s compact size, the locomotives were equipped with A-1-A running gear (to balance the power of the traction motors to avoid wheelslip) and the length was shortened by 1.25 feet (381 mm).

These locomotives were constructed by Đuro Đaković from February 1981 to August 1984 and since the country had diverse ethnicities and languages, the locomotives were lettered in four different languages.

GT22CUM-1/GT22CUM-2

Main article: EMD GT22CUM-1

First introduced in January 1982, the GT22CUM series were locomotives were a powerful single-engined locomotive with light weight per-axle. Designed exclusively for the RFFSA by Equipmentos Villares S.A., the GT22CUM now carried a 'CU' suffix which indicated that this model had six axles (C) and traction motors that could fit from one meter to 5’ 6’’ gauge rails (U). Two custom designations were introduced for this locomotive: 'M' for Meter Gauge and '-1/-2' to indicate a Type 1 or Type 2 model.

Production spanned from January 1982 to May 1986.

All subsidiaries of the RFFSA were consolidated in 1983 with the introduction of the SIGO System by the federal government.

GT22LC

When most second and third world railroads couldn’t operate standard EMD Locomotives due to their weight, EMD introduced the GT22LC, a lightweight model of the GT22C version and incorporated a turbocharger. Although the GT22LC may seem identical as any other GT22C models, the L Suffix indicated that the locomotive has a lighter frame than standard production of export models.

Production spanned from February 1985 to August 1986.

Production spanned from November 1981 to November 1996.
