QUOTE: Originally posted by lionelsoni How about this instead? Put a section with an isolated running rail at each of the four sides of the crossing. Use the isolated rails to operate two relays, each cutting power to the center rails for some distance on the conflicting path. So, which ever train gets to within about 10 inches of the crossing first, cuts power for the other train within a yard or so of the crossing, until it has passed. You could even set up signals operated by the relays, in all four directions.
