The exclusive "Sounder" is a sound-only decoder and speaker that's easily added to any HO locomotive equipped with a standard, non-sound decoder or even any piece of rolling stock being pulled by the locomotive equipped with wheel pickups. The railroader simply "hooks-up" two wires to the track power pickup points in the loco and suddenly can enjoy MRC's rich, Brilliance sound and the world's most extensive feature set. The Diesel's "3" Sounder provides three genuine ALco, "F Unit" and SD60 prime mover sounds like selectable (33) horns, 8- bells, brakes, air releases, pop valves, cooling fans, coupling sounds and more. Using simple soldering techniques, the Sounder can provide a full complement of locomotive lighting effects: Prime Stratolight, Mars, Ditch, Strobe (single and double) and on/off function for internal lighting.
