HO GEN AC4400CW Locomotive FSRR 4421 (ATHG-2048)

HO-scale GE AC4400CW diesel locomotive in FSRR livery, road number 4421. This Athearn model faithfully reproduces GE’s modern 4,400-horsepower freight locomotive, built around a heavy die-cast frame and Genesis drivetrain for smooth, quiet operation. With prototypical paint schemes and carefully researched detailing, it provides a ready-to-run centerpiece that captures the look and feel of the prototype on modern freight layouts.

Designed for both DC and DCC operation, it is DCC-ready with Quick Plug plug-and-play 21-pin NEM connector and features LED lighting with illuminated number boards, as well as front and rear walkway lights. It includes a full cab interior with see-through windows, etched walkways, flexible MU hoses, and a detailed fuel tank for extra authenticity. The all-wheel-drive Genesis drivetrain delivers reliable traction and smooth running on layouts with minimum 18-inch curves, with 22-inch curves recommended for best performance. Sound-equipped versions add onboard DCC with Tsunami2 sound and dual speakers, plus CV-based tuning options to tailor operation.
