I was surfing Con Cor's site last night after recieving a monthly E Flyer from them. The decoders are digitrax. They are also offering decoders for their Arrow Train, Zephyr, and M1000.The twin headlight Zephyr will have a digitrax module to control the Mars Light,but the train has been much delayed because of bankrupcy of their Chinese manufacturer.Nate Goodman (Nato).
