HO SD70ACe Locomotive with DCC and Sound MRL #4308 (ATHG75846)

This HO-scale SD70ACe locomotive with DCC and sound is a ready-to-run model built for HO-layout fans who want authentic diesel power on their tracks. Recreating Montana Rail Link’s unit in its original scheme, it features a nose-mounted headlight, lit number boards, and truck lights, plus an early brake wheel for prototype accuracy and a faithful as-delivered appearance. The onboard DCC decoder with SoundTraxx Tsunami2 sound delivers realistic engine, horn, and bell effects to enhance operation and immersion.

On the rails it delivers reliable performance and high-detail realism. A heavy die-cast frame, eight-wheel drive with precision gears, and all-wheel electrical pickup provide smooth, powerful running, while RP25-contoured wheels and body-mounted scale knuckles keep operations true to scale on most HO tracks. Fine details include etched see-through steps, walkways, lift rings, and a full cab interior visible through see-through windows. The sound-equipped version adds an onboard DCC decoder with Tsunami2 sound and dual speakers, offering full DCC functionality; the sound works in both DC and DCC, and CV adjustments—with a CV chart included—let operators tune performance to taste.
