Conceived by legendary Art-Deco designer Raymond Loey, the Streamlined K4 was the Pennsylvania Railroad's answer to the stylish locomotive design trends of the 1940s. Rebuilt from four standard K4 locomotives for use on express passenger services such as the Jeffersonian and South Wind, the Streamlined K4s would eventually find their way onto all long-distance trains operated by the PRR. Our N scale Streamlined K4 comes equipped with Econami Sound Value DCC featuring the Soundtraxx steam package. Factory set for realism, the steam package offers a choice of 16 whistles, 6 bell types, 4 prototypical chuffs, 5 air pumps, 5 dynamos, cylinder cocks, grade crossing quill, blowdown, brake sqeal/release, coupling/uncoupling, water stop, and "all aboard" announcements with coach door operation effects - all in 16-bit polyphonic sound.
