HO GP40-2 Locomotive with DCC & Sound, SP #7617 (ATHG-1754)

HO-scale GP40-2 diesel locomotive with DCC and sound in Southern Pacific livery, road number 7617, designed for realistic freight operations on HO layouts. This model recreates the classic 1970s GP40-2 with a DCC decoder and SoundTraxx Tsunami2 sound, dual cube speakers, and full DCC functionality while still operating on DC layouts. It uses a Quick Plug 21-pin NEM interface for easy DCC setup, features a see-through cab with a detailed interior, a heavy die-cast frame for traction, and fine-scale detailing such as handrails, etched fan grilles, and accurate paint and lettering. The SP variant captures the as-delivered look with a cab-roof mounted bell, standard exhaust, and split battery box doors.

On the layout, it offers smooth, reliable performance with all-wheel drive and current pickup from all wheels, LED lighting for realistic day and night scenes, and compatibility with common HO track. It’s primed for weathering, giving a natural starting point to add grime or rust, and road-number specific variations are available across multiple road names if you want to expand a roster while keeping SP 7617 as a faithful centerpiece for freight operations.
