HO 4-8-2 MT-4 Early Green Boiler #4350 Steam Locomotive (ATHG71556)

An HO-scale Southern Pacific Mt-4 class 4-8-2 Mountain steam locomotive in the early green boiler scheme, this model faithfully recreates SP’s Mountain-type engine as it ran on rugged mountain routes from the 1920s through the 1950s. It offers authentic detailing such as skyline casing options, metal handrails, a cab interior with details and a backhead with printed gauges, plus see-through running boards with safety tread. Factory-applied detail parts include a brass-painted bell and whistle piping, valves, a generator, air tanks and reverser, and McHenry operating scale knuckle couplers for reliable coupling to era-appropriate tenders. This ready-to-run locomotive is designed for HO layouts and pairs with SP-era rolling stock to deliver the look and feel of classic Mountain service on a hobby layout.

New features enhance realism and performance, including dual cube speakers for robust sound and an upgraded LED headlight for clear operation in any lighting. The upgraded loco-to-tender connection harness, improved electrical pickup wipers, and refined traction-tire-to-rail contact deliver smoother, more dependable operation on curves. The model also preserves key SP design cues—see-through running boards, adjustable cab windows and doors, lighted number boards, and skyline-casing options—while the design supports a minimum 22-inch radius and era styling from 1926 to 1958, making it a compelling centerpiece for Mountain-era layouts.
