HO RTR RS-3 Locomotive DCC Sound New Haven #552 (ATH28774)

An HO-scale RS-3 diesel locomotive in New Haven livery is a fully assembled, ready-to-run model designed to bring authentic mid-century diesel power to a layout. It features DCC control and Tsunami2 sound with a cube speaker, delivering realistic engine noises and smooth operation for an engaging, hands-on rail experience.

Beyond its lifelike detail—metal grab irons, fine-scale handrails, see-through etched radiator fan and cab windows—the RS-3 rides on an all-wheel-drive chassis with a refined 5-pole motor and flywheels for quiet, smooth performance. It uses McHenry scale knuckle couplers (Kadee-compatible) and RP25 wheel contours for reliable tracking, with LED lighting for long-lasting illumination. The DCC-ready chassis accepts a 21-pin plug, and sound-equipped versions feature onboard Tsunami2 DCC/Sound with a cube speaker. Designed for HO layouts with a minimum 18-inch radius, this model combines authentic detailing with dependable operation for everyday use on the railroad.
