What makes this so great?

It really works better than other circuits of this type.   Place each unit close to the turnout it controls.  It has plenty of snap to switch them.   Best of all, no more burned out coils, no core meltdowns, and no more blown transistors.  Small communications wire can be used for the connections from the control panel to the circuit and can be way far away.
