N GEN 4-8-8-4 Big Boy Locomotive and CA-11 Snowbus Caboose Set (ATHG-2079)

An N-scale Genesis 4-8-8-4 Big Boy steam locomotive paired with the CA-11 Snowbus caboose offers a complete Union Pacific era set for your layout. This ready-to-run two-piece collection faithfully reproduces UP’s legendary power and branding and is designed to run on standard N-scale track, making it easy to add scale drama to any layout.

From the locomotive’s boiler backhead with printed gauges, piping and valves, to see-through running boards and cab windows, the model delivers rich, railway-detail realism atop a heavy die-cast frame and body-mounted knuckle couplers for confident pulling. The Snowbus caboose adds interior detail, see-through end platforms, etched screens, and underframe hardware, all weighted for smooth operation. Some variants include onboard DCC sound with Tsunami2, offering chuff, whistle and bell sounds and full DCC functionality, while others operate on DC. The set is built for reliable operation on common layouts with minimum radii of 11 inches for the locomotive and 9-3/4 inches for the caboose.
