HO GEN 4-8-2 MT-4 Locomotive Early Black SP #4351 (ATHG-2109)

HO-scale Southern Pacific Mt-4 4-8-2 steam locomotive in an early black SP livery captures the look and presence of the Mt-4 class, a rugged mountain engine built for demanding service on the SP network from 1926 to 1958. This Athearn model offers detailed realism—from a front coupler pocket for an operating coupler and see-through running boards with safety tread to a boiler backhead with printed gauges and riveted firebox. Factory-applied parts such as a brass-painted bell and whistle, valves, steps, air tanks, piping, generator, air pump, and reverser, plus adjustable cab windows and doors, metal handrails, cab interior detailing, lighted number boards, and optional Skyline casing, all contribute to an authentic silhouette that runs on HO layouts with a 22-inch minimum radius requirement.

Some versions include tender-mounted DCC decoders with SoundTrax Tsunami2 sound, dual cube speakers, and full DCC functionality, with NMRA compatibility and a CV chart for tuning. The Mt-4 model sits within a Legendary Liveries program offering historic paint schemes for fans who want to explore alternate histories, while the SP early black livery on #4351 provides a classic, prototypical centerpiece for mountain routes and era-appropriate layout scenes.
