HO GEN SDP45 Locomotive w/DCC & Sound - UP #1457 (ATHG-2035)

HO-scale SDP45 locomotive with DCC and sound in Union Pacific livery, UP 1457. This Athearn model faithfully recreates the 1960s SDP45 diesel, a long-hood design built to replace aging E-units, and it features the distinctive steam generator compartment that defined the class. The UP-numbered unit is available in Legendary Liveries, an Athearn exclusive offering iconic paint schemes for collectors, while the standard UP finish provides a ready-to-run, prototypically accurate centerpiece for an HO layout.

Under the hood lies a Genesis driveline with a 5-pole motor and precision flywheels for smooth, reliable operation, along with all-wheel electrical pickup and RP25 wheel contours for compatibility with common HO track. Details include LED lighting, a detailed fuel tank, fine-scale Celcon handrails, a full cab interior, and body-mounted McHenry knuckle couplers. The sound-equipped version features a DCC decoder with SoundTraxx Tsunami2 sound and dual speakers for robust audio, plus NMRA compatibility and CV-adjustment options for fine-tuned control. This model is designed for HO layouts with a minimum radius of 18 inches and a recommended radius of 22 inches to ensure smooth operation.
