An articulated engine that provided tremendous power at high speeds, the EM-1 was ideal for hauling passengers and heavy loads of coal up and down the Appalachian Mountains. It joins our N scale Spectrum® line equipped with an Econami™ SoundTraxx® steam package. Factory-set for EM-1 realism, the steam package offers a choice of 16 whistles, multiple variations of 6 bell types, 4 prototypical chuffs, 5 airpumps, and 4 dynamos plus cylinder cocks, grade crossing signal, blowdown, brake squeal/release, coupling/uncoupling, and water stop—all in 16-bit polyphonic sound.
