Showing off the crosswalks for the Factorio train intersection that I designed. They use 3-way switches and cross over tracks to divert traffic to the other side of the rails. Occasionally a train will still cross through that section of the tracks, but it's a result of the left over train pathing prior to closing those tracks. Once the intersection clears the crossing will be clear until you open it again.
