HO SD40T-2 Locomotive with DCC and Sound, BN #8217 (ATH71851)

HO-scale SD40T-2 Locomotive with DCC and Sound, BN 8217, is a detailed, sound-equipped HO model designed for realistic operation on modern layouts. This six-axle tunnel-motor features an onboard DCC decoder with SoundTraxx Econami sound and LED lighting, with full DCC functions available in DCC mode and DC operation for non‑DCC setups. It also incorporates DCC-ready 21-pin NEM Quick Plug technology for easy decoder maintenance or upgrades.

Built for authenticity and reliable performance, the model showcases fine-scale detailing such as see-through cab windows, etched windshield wipers, and separately applied air tanks, plus all-wheel drive and a robust five-pole motor with flywheels for smooth, quiet running. Nickel-plated, blackened machined wheels with RP25 contours ensure solid tracking on popular layouts, and the chassis accepts a Genesis motor retrofit for higher power if desired. Legendary Liveries offer paint schemes that recall famous prototypes, while prototype notes describe the SD40T-2 as a 3,000 hp tunnel-motor built by GM-EMD between 1974 and 1980 for tunnel cooling; for operation, a minimum 18-inch radius is recommended, with 22 inches preferred for optimum performance.
