As a new modeler, I use EZ Track. How do I turn power off on sidings and spurs to park trains?
You do that just the same as any other brand of track. You insulate one rail, either by using an insulated rail joiner or by cutting gaps in the rails. You then wire the siding to an on off switch (SPST) or if you want the option of either of two power packs to conrtol it, you use a SPDT switch with center off.
