HO RTR RS-3 Locomotive NH #552 (ATH28674)

New Haven RS-3 Locomotive, NH 552, HO scale — a fully assembled, ready-to-run model that faithfully recreates the New Haven Railroad’s postwar diesel era. This high-detail RS-3 features a painted and printed injection-molded body, see-through cab windows, a see-through etched radiator fan, metal grab irons, fine handrails, and accurate decoration that brings era-specific character to your layout.

Available in DCC-ready form with a 21-pin plug or as a sound-equipped model with Tsunami2 DCC/Sound and a cube speaker, the RS-3 delivers modern performance. It uses a stronger, smoother 5-pole motor with flywheels for quiet operation, plus all-wheel drive and electrical pickup for reliable power, RP25 wheels for compatibility across brands, and McHenry scale knuckle couplers that are Kadee-compatible. LED lighting enhances realism and longevity, while the model rides on HO curves with a minimum radius of 18 inches. Window packaging provides clear viewing, and an interior blister keeps the model protected during storage.
