N GEN 4-8-8-4 Big Boy Locomotive NdeM #4000 (ATHG-2252)

An N-scale Genesis 4-8-8-4 Big Boy locomotive in NdeM No. 4000 livery, this ready-to-run model brings the scale and presence of a legendary 4-8-8-4 steam locomotive to a model railroad. It’s built for serious hobbyists who want an accurate, display-worthy replica that can perform on an N-scale layout and serve as a striking centerpiece in a roster of locomotives.

Detail is at the core, from the boiler backhead with printed gauges to see-through running boards and cab windows, all mounted on a heavy die-cast frame with a five-pole motor for solid traction. Body-mounted scale knuckle couplers and bidirectional LED lighting enable authentic coupling and operation, while a minimum 11-inch radius accommodates a wide range of layouts. Road-number options include #4000 (as-delivered), #4003 (primed for grime), #4019 (smoke lifters), #4020 (as-delivered), and #4024 (Legendary Liveries Greyhound with yellow trim, smoke lifters, oil burner, no cooling pipes); the NdeM edition features an oil burner and no cooling pipes. Sound-equipped variants add an onboard DCC decoder with SoundTraxx Tsunami2, delivering chuff, whistle, and bell sounds and full DCC functionality, with DC/DCC operability and MU lashups; others are offered as non-sound ready. Primed for grime, this model provides an ideal starting point for weathering to resemble an in-service locomotive.
