HO GP38-2 Locomotive Sound-Ready with Speaker UP #551 (ATH72197)

HO GP38-2 Locomotive — Sound-Ready with Speaker in Union Pacific livery is a ready-to-run HO-scale model designed to bring realistic freight and switching operations to HO layouts. It includes a built-in speaker for authentic locomotive sounds and is DCC-ready with a 21-pin NEM plug, allowing quick digital control. Fully assembled and decorated with careful Union Pacific detailing, it presents a convincing prototype appearance right out of the box.

Inside, a heavy die-cast frame provides traction and durability, while a 5-pole motor with precision flywheels and a multi-link drive ensures smooth, quiet operation. Realistic details include see-through cab windows, Celcon handrails, and individually applied grab irons, plus LED headlights and ditch lights (and beacons on versions that include them). It rides on nickel-plated, blackened machined wheels with RP25 contours and uses McHenry operating scale-knuckle couplers for reliable coupling. Designed for HO layouts with an 18-inch minimum radius (22 inches recommended), and replacement parts are available if needed.
