Kato's Insulated UniJoiners are used for electrically separating sections "blocks" on your layout. A "block" is a section of track long enough to hold a complete train (minimum requirement) on the main line or short enough to hold just a locomotive on a siding in a yard. This makes it ideal for additional operations and controls under DCC and which also allows for more advanced train detection.
