I was looking at several pieces of K-Line Super Snap track and could not see any electrical connection between the two outside common rails, like the metal strip on the underside of FasTrack pieces. This may not be an issue, since any wheel truck with metal axles and wheel would connect the two outside rails. My question is twofold -- 1) is there some electrical connection between the K-Line Super Snap outside rails I didn't see, and 2) if not, would it make any difference as far as isolating a track section for accessory control?

The outside rails are isolated from each other, makes it easy to make an isolated outside rail to trigger accessories.
I agree with Darrell! It is all I use on my 13" by 32" layout and all we use it on our club layouts. It works perfectly for isolated rails and triggers accessories flawlessly. I do have some sections where I soldered a wire to the outer rails to connect them. The wire fits perfectly between the rails and black or brown wire blends in. It is too bad someone doesn't still make Super Snap track. It is hard to come by.

I use Supersnap with isolated track sections as well. I will point out that one isolated track section refused to work. It was a real forehead slapper as others I had already installed worked fine. after testing all the connections and circuits I found a thin black steel strip on the underside of one of the black plastic ties, nearly undetectable. It was on a filler piece of track which I may have cut off of a 90 degree crossing however I don't have another 90 to verify that. long story short; if your accessory refuses to operate after the normal isolated section hook up is made, check the underside of each track section in the block for the presence of a jumper
Darrell, dennish and Cmac -- thank you very much for your replies. My apologies for not acknowledging sooner -- we've been moving back into our house after a big remodel. I had to put thoughts of trains aside while we've been trying to get resettled, but that's no excuse for bad manners and not checking the Forum for replies.
But to the point, I really appreciate your positive words about SuperSnap. It's cleared the way for me to use the track on my layout.

Bob,
One thing I found helpful with the SuperSnap track was to use a piece of tubular track with it in a tunnel or someplace where the tubular track is not visible. That way the outside rails are tied together electrically. It's particularly helpful in areas where you are coming in to a switch or switches because of the fiber pins in the switches. Also, if you mate the SuperSnap to tubular track, remove the metal tabs under the SuperSnap center rail. That way those center rail metal tabs do not touch the tubular track tie and cause a low grade short that is difficult to track down. You can still isolate an outside rail where desired.
