HO GEN SDP45 Locomotive with DCC and Sound Union Pacific #1450 (ATHG-2034)

HO-scale SDP45 locomotive with DCC and sound in Union Pacific UP #1450. This detailed Athearn model reproduces the SDP45, a 1960s-era evolution that added a steam generator in the long hood to extend service life, and it sits in the Legendary Liveries lineup, an exclusive program offering iconic paint schemes and alternate roster concepts for collectors and protofreelancers alike.

Inside, onboard SoundTraxx Tsunami2 sound and a DCC decoder deliver authentic locomotive audio with two speakers and full DCC functionality, while the Genesis-style drivetrain, five-pole motor, and heavy die-cast frame provide smooth, reliable operation. The model features LED lighting, fine-scale Celcon handrails, body-mounted knuckle couplers, and detailed fuel-tank components, with UP-specific detailing such as icicle breakers and a winterization hatch. Designed for HO layouts, it performs best on curves with an 18-inch minimum radius (22 inches recommended) for optimal tracking and realism.
