Wiring multiple Terminal Tracks into a layout.

    It is much easier to add a terminal block between the power supply and multiple terminal tracks.   Shown are the four ways that two cars can pass through a terminal track in your layout.   If you are not using the terminal track screws or plugs notice the rail indicators on the track sections.

    Use anyone of the wiring diagrams at the top of this page, but wire to a terminal block instead of the terminal track.   All tracks or power taps should be connected from the top of the terminal block.   For clarity the wire colors change at the terminal block.   The color of the wire does not matter only that the ends are connected correctly.

    Problems may result from using common ground terminal tracks.   Be sure to cut all common ground straps, even the ones impersonating a straight track.

Adding Terminal Tracks

    Notice the gaps in the layout are for testing in a Counter Clockwise direction.   Also notice how the terminal tracks are all in the same direction but the screw colors are not the same pattern.  

    One of the above wiring diagrams should be used to connect the first terminal track.   All additional or secondary terminal tracks or power taps should be connected from the wires connecting to the primary terminal track.  

    Problems may result from using common ground terminal tracks.   Be sure to cut all common ground straps, even the ones impersonating a straight track.

    To make additional terminal tracks less obtrusive in the layout, consider cutting the screw or plug block and all of the straps (leaving enough room for a 1/4" Electrical Spade Terminal to be slipped onto the stub of the straps).
