Al this may or not be new, but you may want to include it in the wiring peco Unifrog turnout section. ?The peco Unifrog has a wire to power the frog. ?The wire is not insulated and it is located very close to the wire jumpers that power the rails past the frog. ? Due to the wires being so close together it is very easy to accidentally short the frog wire against either of the other two wires. ?Folks using the Unifrog should take care when installing them, or insulated the frog wire.
