Re: Resistance Leak from Fast Track turnouts

Hi Gang:

A friend used so much graphite on a turn out that it caused a current path.

Brent, Chris is probably correct about the flux.
The problem is a path from the top copper of one rail to the bottom copper of the tie strip and back to the other isolated top copper.
I always cut gaps on the bottom side of the ties to avoid that problem in the future from ballast or anything else after installation.

I didn’t think Fast Tracks supplied double sided ties.
Our club used double sided for a short while years ago. We had considerable leakage between the top and bottom after we ballasted.
We then slotted the bottom below the top - a little better.
Then we slotted just below the rails - a little better still.
Then used a soldering iron to heat and peel the foil from the bottom of the ties - problem solved.
Hope you haven’t got your turnouts glued down.

There should be _infinite_ resistance between opposite rails, as they are (hopefully) isolated from each other.   If you have less than infinite resistance, you have some leakage between the two rails.  Have you ballasted this area recently using water/glues/alcohols ???? Residual moisture from this application could create a high resistance path between rails of alternate polarity.

There should be infinite resistance between opposite rails unless you have some type of connection between them.

Re: PSX-AR Installation Query

Don Vollrath
 

Filling an isolating gap with styrene does prevent a steel wheel from falling into the crack and touching both rails at the same time.... except possibly in curves where the side of the wheel flange May touch the side of the rails. This requires a wider filled gap. AND it doesn’t cover the case where multiple axles and wheels are electrically connected together at a power pickup truck. Think - another loco or passenger car truck
