Class One Model Works LM00460 EMD GP40-2 1A3 Rebuild Union Pacific UP 1531 DCC & Sound with Tru-Fans

This HO scale GP40-2 1A3 rebuild captures the distinctive character of UP with exceptional prototype fidelity. Rebuilt under Union Pacific’s in-house 1A3 program, these locomotives reflect the railroad’s commitment to extending the life of its dependable GP40-2 fleet—upgraded mechanically while retaining the rugged versatility that made them staples of mainline and local freight service. The model faithfully mirrors those refinements, delivering crisp paint, accurate lettering, and road-specific detailing.

Factory-equipped with DCC and premium sound, it offers smooth throttle response, dynamic audio realism, and operational flexibility straight from the box. The addition of Tru-Fans elevates the roof detail to a higher standard, providing see-through, scale-accurate cooling fans that add depth and authenticity rarely found in ready-to-run power. With refined drive components for reliable slow-speed performance and sure-footed pulling power, this locomotive is equally at home leading a priority freight or handling local duties on a contemporary Union Pacific layout.
