Our main focus has been controlling locomotives (HO and N scale), however we found that our module can also control a two (2) position turnout without any modifications. We have always planned on developing a new module dedicated to turnout control, however using our current module at least gives you the option.
The pictures below show how we installed two modules, each controlling a 2 position turnout as well as separate outputs. Since you wire up the turnout to the wires typically used for the locomotive motor, you still have two outputs free for accent lighting. We decided to add a light to the switch house as well as lamp lighting for the turnouts. For ease of use we used two 9V batteries in series with a toggle switch (mounted in the windows of the building).
