That is my plan for 3 or 4 sidings that I'll use to park engines. I have the relays for turning siding power on and off. I have two staging tracks that I turn power off now so the EOTs don't sit blinking all the time. I'm thinking of wiring in a time delay relay that will turn TIU channel power off when I select and engine siding and the delay relay will turn the channel power back on after a few seconds. It means dedicating a TIU channel to the engine parks but I have two not being used.
I keep watching for RC boards to show up on the parts site but I doubt they ever will.
