I did one. Only took me three tries to get it right (!) First two times it ran backwards (when on DC).
I used the Digitrax decoder sold for the MT SW1500. I don't recommend that one if you are to to run the locomotive on DC sometimes.
[ adding a little more ] The installation was more than a little fiddly - getting the board to sit in the frame and make proper contact took a little doing. My experience might be specific to the Digitrax decoder.
