GG1 Electric -- DCC Sound Value Locomotive PENN CENTRAL - BLACK W/WHITE LETTERING - #4853 - HO Scale. The electric GG-1 was introduced in the 1930s by the Pennsylvania Railroad, which needed a locomotive that could carry more rolling stock at greater speeds. Its dynamic streamlined design captured the public's imagination and made it the star of countless movies and advertisements. This DCC sound-equipped model includes our Sound Value SoundTraxx sound package with prototypical motors with blowers, pantograph extension and retraction, air compressors, short and long horns and bell–all in 16-bit polyphonic sound. Features include all new tooling, die-cast frame, 12-wheel drive, twin operating metal pantographs that can be powered by overhead wire if desired, soft white LED directional headlights with dimming function and E-Z Mate Mark II couplers. Performs best on 22" radius curves or greater.
