Isolating O36 Manual FasTrack Switches

I just remove the pin or actually cut it off with a Dremel tool. Then I grind it down a bit to leave a small gap ensuring no electric contact.

Where on the switch did you remove the pin? where the switch joins the new loop? or at the beginning of the switch? I have a three track layout with switches spaced as  DM&E Bobby does. each loop is independently powered. I am experiencing issues with that and as one friend has explained to me, I have to isolate the switches.

Thank you !!!  

First, if both transformers are phased correctly and both loops are being operated at the same voltage, you would not necessarily need to isolate the switches. If the loops are being operated at different voltages, such as conventionally on one loop and command on the other, then yes.

Assuming these are crossovers, I would use the 1 3/8" piece between the divergent end of each switch where they meet, in order to isolate. If that is not workable or practical, then remove the center pin from the divergent end of each switch where they meet. That should prevent power from being transmitted from one loop to the other.

Generally, removing the pins should create enough of a gap so there is no contact between the rail ends. You can cover the ends with a non-conductive material like tape or you could fill the gap by taking the plastic tab on a loaf of bread or some flat styrene and cutting it down to size and inserting it between the ends.
