HO SD50 Locomotive BO #8581 (ATHG-1834)

HO scale Genesis EMD SD50 Locomotive from Athearn Genesis faithfully reproduces EMD's 3,500-horsepower SD50 from the early 1980s. This transition-era model features new tooling, accurate door placement and weld marks, and a full cab interior visible through see-through windows. Built on a heavy die-cast frame, it delivers solid traction and smooth, quiet operation, while a Genesis driveline and all-wheel electrical pickup contribute to realistic, dependable performance. It is DCC-ready with Quick Plug plug-and-play technology and a 21-pin NEM connector, making decoder installation straightforward, with optional Tsunami2 sound for an immersive railroading experience.

Road-name specific variants reproduce authentic Chessie/BO heritage and other 1980s–1990s schemes, with prototype details like dynamic brake placement, correct handrails, and carefully painted lettering. Sound-equipped models feature onboard DCC decoders with Tsunami2 sound and dual speakers, while all NMRA functions are accessible in DCC mode. The SD50 is designed for standard layouts (minimum radius of 22 inches), delivering robust pulling power and reliable operation for everyday operations on modern-era layouts.
