I have Atlas 3-rail track on my layout and I want to wire the RailKing Crossing signal with sound (separate speaker) so that I can simply push a button (or allow a 7 year old to do it) so that the lights flash and the sound unit works. I don't want to use an infrared detector so, is there a simple way to accomplish this? How do the wires get connected to the power pack (in this case, an MTH Z1000).
Thank you.
