HO GP40P-2 Locomotive SP Speed Letter #7600 (ATHG64834)

HO GP40P-2 Locomotive SP Speed Letter 7600 is an HO-scale model recreating Southern Pacific's GP40P-2 freight locomotive in the Speed Letter scheme. It’s designed for SP-era freight operations on HO layouts, capturing mid-1980s rebuilds such as a larger fuel tank, removal of steam generator equipment, and a full front lighting package with lit number boards for an authentic look.

Road-number specific details include a Speed Letter repaint and 80s-style front lighting with Gyra light and red warning light effects in DCC, as well as features like a roof beacon, front ditch lights, and the horn relocated to the long hood. The model benefits from a heavy die-cast frame, Blomberg trucks, see-through cab with interior, fine-scale handrails, etched fan grilles, and body-mounted McHenry scale knuckle couplers. It is DCC-ready with Quick Plug plug-and-play using a 21-pin NEM connector, and some versions offer onboard SoundTraxx Tsunami2 sound with dual speakers for engine, horn, and bell sounds; it’s well-suited to grime/weathering for an in-service look and will operate on HO layouts with a minimum radius of 18 inches.
