Re: Staging yard wiring question

Why is it that no one reads the original post any more?  As I said, there is a relay, and a block detector, for one rail of each track.  My question was focused on the best wiring of the second, common, rail.

I did this exact thing for the exactly the same reason.  In doing so, it prevents the command station from seeing a surge in voltage and therefore, a total power shut down.

To make the routing of power to a specific track as simple as possible, I use two, 12-position rotary switches, skipping every other contact so I am never more than one click away from shutting off the power to that track (each rotary switch controls the power to 6 individual tracks).  I also placed a power reading LED neatly between the ties to confirm a "visual" when power was on.  But this feature is no longer needed because all 12 tracks hold "favorite" trains with lighted interiors, along with their startup of sound.  You immediately know what track you've selected . . . .

One reason to have each track separately wired would be to prevent all the sound equipped engines in the yard from starting up at the same time when you power up!
