EMD GP39-2 Phase 1

Union Pacific #1234

Atlas Master Gold Series quality meets one of Union Pacific's versatile second-generation diesel locomotives in this highly detailed N scale model.

Product Overview

The EMD GP39-2 was part of Electro-Motive Division's successful Dash 2 locomotive family, combining proven reliability with improved electronics and performance. Built between 1974 and 1980, the GP39-2 delivered 2,300 horsepower and found service on a variety of railroads across North America. Its versatility made it equally at home handling road freights, local service, yard transfers, and branch line assignments.

Union Pacific, one of America's most iconic railroads, traces its roots to the Pacific Railway Act of 1862 and played a central role in completing the nation's first transcontinental railroad. Today, Union Pacific operates one of the largest freight rail networks in North America, serving customers across the western two-thirds of the United States. Its distinctive Armour Yellow locomotives have become some of the most recognizable railroad equipment in the world.

Locomotive #1234 represents Union Pacific's commitment to maintaining a versatile fleet capable of handling everything from mainline freight operations to local switching assignments. The GP39-2's compact size, dependable performance, and Dash 2 technology made it a valuable asset throughout its career.

Atlas's Master Gold Series model captures the appearance and character of this locomotive with exceptional detail, smooth operation, and factory-installed ESU LokSound sound and DCC capabilities, making it a standout addition to any Union Pacific roster.
