How do you power your Tortoise? My staging yard is a loop and all turnouts (H0 / H0n3) are powered with Tortoise. I've developed a wiring scheme where I choose the track and the turnouts get the power via diode matrix. At first an example with four tracks: The turnouts are labeled with a, b and c. And they have normal position, straight with + and the reverse position with -. Each Tortoise gets at one contact ground and with the other contact plus or minus! You see my full diagrams at my Pueblo & Salt Lake RR site. Wolfgang
