Don: Solution is to make each point the same polarity as the stock rail it mates with. The problem will go away. But you will have to isolate the frog and have its polarity change as the route changes. Paul

Suspect setting the points to always clear the blind drivers would make the turnout look like toy train template! Don McGovern 3a. Re: PC Switches Posted by: "Paul Vaughn" [email protected] pv_sn3 Date: Fri Sep 28, 2012 8:41 pm ((PDT)) Richard: If the points are SET to just clear the Check Gauge then it will be impossible to short the back side of any wheel set with an open point rail. This also assumes that the wheel set is correcly set to the check gauge. If a wheel set is shorting the first thing to check is the wheel check gauge, front side of one flange to the rear of the opposite flange. NOTE: the wheel check gage and track check gage MUST BE EQUAL!!!!! If they are not, all bets are off and shorts could occure. I agree that a point should be the same polarity as the adjacent stock rail and this will also stop any shorting. This requires a PC throw bar be gapped. This brings me to my statement; DC or DCC requires a reversable frog politiarty. Therefore No such thing as DCC compatable/friendly. Paul ------------------------------------ Yahoo!
