I was looking up the decoder manual for my Atlas Locomotive witha 4 function decoder on the Atlas site and noticed that the PDF of the maunal says that it is a Roco decoder. I never knew Atlas and Roco were partnered for the DCC that Atlas sells. I had a chance to get one of the Roco "train set" DCC systems for something like 70 dollars from my LHS in an open box deal I was offered when his Digitrax orders were all backordered indefinitely. I instead bought his in house Zephyr system off the stores layout at a reduced price. Now I sorta wish I had picked up thew Roco set as well.
