HO SW1500 Locomotive with DCC & Sound, Southern Pacific #2556 (ATH29768)

An HO-scale Southern Pacific SW1500 switcher locomotive No. 2556, offered with DCC and sound, brings authentic yard operation to an HO layout. Powered by a 1,500-horsepower EMD 645E twelve-cylinder engine, this model faithfully reproduces SP’s late-1960s switcher with a compact profile and the railroad’s distinctive lighting package.

Prototype-accurate details abound—from lit ground lights and a detailed cab interior to drop steps, MU hoses, dual exhaust stacks, printed numberboards, fine-scale handrails, and see-through radiator grille and cab windows. The model uses McHenry scale knuckle couplers, RP25 wheels, and all-wheel drive with reliable electrical pickup for smooth, quiet operation. It is available in DCC-ready form with a 21-pin NEM connector or in DCC & sound versions featuring Economi sound with a single cube speaker and LED lighting. With an 18-inch minimum radius and a rugged injection-molded body, this SP switcher blends realism with dependable performance, and new features include operating ground lights and a more powerful, quieter can motor.
