Might be too short a section or there is a leak

Many moons ago; I constructed a pretty large O gauge loop for a friend of mine that wanted three Budd sets to run on this elevated section.  I used insulated track and relays. It ran pretty well and then all of a sudden there were cases where a train would pass the block.  I found that at the end of the insulated section there was a carbon deposit across the gap. It seemed like it was dragged across the  insulating pin. There was a thin sliver of carbon deposit across the gap. When I cleaned it the problem went away.
