David- Both outside rails are fully grounded. My switches are manually thrown. The only thing left I could ground would be the points themselves since they don't seem to make very good continuity just from my ground throws pushing them against the outside rails. All that said it seems quite possible that the problem is loss of ground even still as the stalls seem to frequently happen just at the moment one of the grounded wheels rolls onto a plastic frog or other component of the switches. I wish RCS would use metal frogs...everything else about them is so top notch. (I've actually been to their shop and seen how they build things--very impressive!)
GRJ- I take it you think the supercap is the best fix, but also far and away the most daunting and risky for me to DIY... Any thoughts on adding pickups? that would seem like it may accomplish the same thing and be less invasive?
