HO SDP40F Locomotive with DCC & Sound, EMD #268 (ATHG64221)

HO Scale SDP40F Locomotive with DCC & Sound, Amtrak #268 — a detailed, ready-to-run HO model that recreates Amtrak’s SDP40F as a testbed for advanced electronics. The locomotive includes a built-in DCC decoder with SoundTraxx Tsunami2 sound and two speakers for realistic engine, horn, and bell effects, and it features illuminated ground lights, classification lights, and number boards to capture the prototype’s distinctive lighting. Front and rear trainline hoses plus see-through intake grills further enhance the model’s on-layout presence.

On the rails, this SDP40F delivers dependable performance: eight-wheel drive with precision gears and all-wheel electrical pickup, backed by a heavy die-cast frame for traction. It offers a full cab interior, walkways, wipers, and fine Celcon handrails, along with a DCC-ready Quick Plug system and 21-pin NEM connector for easy decoder upgrades. It runs on both DC and DCC, supports NMRA‑compatible functions, and includes a CV chart for adjustments; RP25-contoured wheels ensure smooth operation on common HO track. The design nods to the prototype’s history as a Siemens-equipped testbed in 1988, adding an authentic touch for Amtrak-era layouts.
