I've been reading about runaway trains on sidings and how the lack of the watchdog signal is the cause of this. My layout consists on 5 yard tracks and I am planning on putting a toggle on each track to be able to turn the tracks on and off. If one of my handles from the Z4000 powers only those 5 tracks connected to it, do I have to turn the transformer off and back on again to generate a watchdog signal or can I just bring the one handle to zero then push it back up to apply power and generate the watchdog signal?
