Are both loops actually insulated from each other?
Gregg,
unless it's Ross ready it's not pre wired.
that aside coming from outer loop to inner loop you wire the rail prior to crossing the diamond and then the other rail after the diamond with a hot wire so pickup rollers get power the outer rails that engines wheels travel on are wired to common.
The Ross double crossover has both loops insulated from each other the picture below will help you see what I mean. this is the pre wired diagram. but basically rails marked 1-1 gets its own power wire
and 2-2 gets its own power wire usually controlled by a relay and switch output contacts so if a train coming across 1-1 those rails are hot the and 1-1 are dead and vice versa.
as you can see from photo unless we ourselves good wiring it up the switch itself keeps the loops isolated.
hope that helps clear up how it gets wired.
