All Atlas (and Peco) crossings are completely insulated -- if they weren't they'd cause a short as soon as they were installed.
To my knowledge, all of the Atlas crossings are fully insulated. I have two different sized Atlas crossings, and they both are "wired" at the factory to prevent shorts or loss of power.

Each leg of the "X" are elecetrically separated from each other. I just put a meter on mine...

If anyone is familiar w/ Atlas N scale code 55, i'm wondering if the tracks in a 60 degree crossing are insulated from each other? I assume that they are, but we all know what happens when we assume anything.
My design has one such crossing in the midst of a reversing loop for two different main lines, so i'm thinking that i'll have two independent reversing blocks.
Thanks.
