Diesel WOW121 Decoder and Diesel WOWMotherboards with built-in Keep-Alive™

Use a TCS motherboard with built-in Keep-Alive™ and our WOW121 decoder for a simple installation. Simply remove the original lighting board, replace it with the WOWMotherboard (wired exactly the same as the original light board), and plug-in your WOW121-Diesel. You may need to install a speaker, depending on the locomotive, but all of the connections and power are handled cleanly and simply through the WOWMotherboard.
