HO GP9 Locomotive with DCC and Sound, Penn Central #7506 (ATHG82835)

The GP9 locomotive with DCC and sound in Penn Central livery (7506) is an HO-scale diesel model built for realistic operation and display on modern layouts. This ready-to-run locomotive reproduces the look and feel of a mid‑century GP9, delivering onboard sound and DCC control for authentic performance on HO tracks.

Built around a heavy die-cast frame for traction, it features fine prototype detailing, including a full cab interior, see-through cab windows, etched radiator and fan grilles, scale handrails, and textured walkways, all mounted on Blomberg-B trucks with RP25 wheel contours for smooth operation. The model is DCC-ready with Quick Plug plug-and-play technology using a 21-pin NEM connector; the sound-equipped version includes a DCC decoder with SoundTraxx Tsunami2 sound and dual speakers for rich, realistic engine, horn, and bell sounds that work in both DC and DCC modes. It offers precise slow-speed control, NMRA-compatible functions, and the ability to lash up multiple units, with a CV chart included. Minimum track radius is 18 inches, with 22 inches or larger recommended for optimal performance.
