Union Pacific Mainline Power

Dekosoft Trains presents modern era locomotives in Union Pacific Mainline Power for Open Rails. This set includes General Electric AC44CW, AC45CCTE and EMD’s SD60M and SD70M models with prototypical details and high resolution textures, custom sounds and 3D cab views.

General Electric introduced the AC4400CW (UP class CW44AC) and the similar Dash 9-44CW in 1993. These advanced technology locomotives saw great success in deployment Class 1 railroad across the US. Both models are powered by the 4,400 horsepower 7FDL16 prime mover and ride on six-axle high adhesion trucks. In contrast to the Dash-9, the AC units use alternating current traction motors instead of direct current to provide improved performance at low speeds and electronic controller technology for maximum pulling power in adverse conditions.

Union Pacific rostered 1,338 AC4400CWs, including patched units acquired from Southern Pacific and Chicago and Northwestern mergers. Later models were updated with Computerized Traction Software and designated AC4400CW-CTE. This unique UP safety modification limits the amount of horsepower delivered when the units are in helper service in the middle or at the rear of a train.

The EMD SD60M evolved from General Motors’ long history of producing high horsepower road units. In 1984 EMD introduced its 60 series to extend and replace fleets of six-axle SD’s, and succeed its highly popular SD40-2. Facing strong competition from General Electric, the EMD models raised performance through introduction of the 710G power plant yielding 3,800 horsepower. Union Pacific purchased 366 SD60Ms with three window and two window variations.

EMD’s SD70M carried forward the advances of the SD60 series with a 16-cylinder, 4,000 horsepower prime mover, standard safety cab, modular electronics and the introduction of the HTCR self-steering truck to provide improved traction and lessen wear on rails. After 2000, larger flared radiators were added to improve cooling efficiency and meet EPA Tier 1 requirements. Union Pacific recieved over 1,500 units in multiple orders. Our model features new sounds, 3-d cabview and flared and non-flared versions with high poly details and 2k resolution textures.
