HO SD70ACe Locomotive with DCC and Sound, UP #8518 (ATHG75650)

HO Scale SD70ACe Diesel Locomotive with DCC and Sound in Union Pacific livery UP 8518. This modern HO model mirrors the EPA Tier II-era SD70ACe upgrade, powered by a 16-cylinder, 4300-horsepower diesel engine, with DC traction current chopped back into AC to feed the traction motors. It captures the distinctive UP styling and detailing, making it a convincing centerpiece for yards and mainline runs on HO-scale layouts.

Inside, a built-in DCC decoder with SoundTraxx Tsunami2 sound delivers engine, horn, and bell audio through two cube speakers, and it can operate on both DC and DCC layouts with full DCC functionality. The model comes fully assembled and ready to run, with NMRA-compatible CVs for lashups and tuning, plus scale detailing like lit number boards and truck lights. For smooth operation, a minimum 18-inch radius is recommended, with 22 inches or more preferred for best performance.
