I am wondering if there is a difference between 2 and 3 rail electronics. I have an Atlas 3 rail SW8 switcher that the Railsounds doesn't work in. I recently picked up a complete 2 rail set of electronics for an Atlas 2 rail SW9. I am thinking of using the Railsounds board for a replacement if needed. I have yet to take it apart yet so I don't know what is wrong.
