HO SW1500 Locomotive with DCC and Sound Southern Pacific #2577 (ATH29771)

HO-scale SW1500 switcher locomotive in Southern Pacific livery with DCC and sound, numbered 2577. This 1,500-horsepower switcher is designed for realistic yard and industrial switching on an HO layout, delivering authentic engine tones, horn, and bell through an on-board decoder for immersive operation.

Details reflect SP's distinctive features, including a large cab-front number board and a full lighting package, plus lit ground lights, a detailed cab interior, MU hoses, dual exhaust stacks, see-through radiator grille and cab windows, and fine-scale handrails. The model rides on RP25 wheels with all-wheel drive and McHenry scale knuckle couplers and uses a 21-pin DCC plug for easy setup. In the DCC and sound version, a SoundTraxx Economi sound system offers engine, horn, and bell sounds with a single cube speaker and NMRA-compatible operation in DCC mode; new features include operating ground lights and a quieter, more powerful can motor. The SW1500 was a four-axle switcher built by GM-EMD between 1966 and 1974 for light branch and industrial service.
