The outside rails of a tubular track section are electrically connected through the ties. In order to make an insulated section, besides the the insulating track pins, you need to remove one of the outer rails and insulate it, by whatever means (I use middle rail fiber insulators from junk track), then re-install it to the crossties. Once you have done that you can use the fiber pins (modern ones are plastic) to create an insulated section.

Un bend the tabs holding the track. reinstall with a small piece of electrical fishpaper sandwiched in between. Do not use electrical tape or cardboard,it can rip through...


Please excuse me for pointing this out, but except for "Do not use electrical tape or cardboard,it can rip through," this description is not very clear, to put it mildly.

Yes. The fishpaper caution was the clear part. "Unbend the tabs holding the track," however, seemed a little vague to me. The fact that someone is even asking the question indicates a need for a more explicit instruction, which is up there in the third posting.

By all means, why not add the detail that you deem necessary?
Nick, I have the same kind of track you do. I would open the tab on the track wide enough so that you can slide the rail out with enough clearance so that you can slide it back in with a couple of layers of black electrical tape to insulate it from the ties, then recrimp the loose tie clamps. It does not need to be real tight. You will know when. 2 layers of tape will work fine and not cut through. I have had mine like this for 5 years and it still works fine.

Do the above with as many lengths as you need.. Don't forget the plastic pins at each end of your insulated section. Have fun doing it.

Oh, and don't take the pranksters too seriously.
Then based on what's been said here, you probably now know what to do. If it were me and money were not a big deal, I'd see if the LHS has some sections already made with the insulated feature. Many shops also have used, older tinplate O Gauge track real cheap or almost free. It doesn't sell well at all and sometimes customers just bring it in and leave it. Search thru the odds and ends boxes and you may find some insulated.

You can also do infra-red train detection devices and skip all this.

And remember, train detection no matter how is only half the issue. You still have to plan for a relay switch.

One of the guys here can I'm certain post a simple diagram for how to wire up a relay switch. The leads go three places, the insulated section, the accessory and the transformer. It's not rocket science but there is a certain amount of learning and work involved.

I've never used an infra-red but I think they come with the relay switch already installed. Otherwise, you can do it yourself with a trip to Radio Shack.

Just let us know how we can help.

Already did. Why not check it out?

OK so here is my question. I am running the o27 tubular track and I have a few sidings where I can't see the end of the track well. I am going to put an led light at the end of the track and want to use a small price of track and insulate it so it will light the led when it hits that section. Now where I am stumped at is of I have a freight car on the end that makes no contact with the center rail only the outside 2 how will it activate my light?
