    Cool!

    The overpass layouts are the same length in both lanes. The only way to get both lanes the same length is to have one loop from the crossover run clockwise and the other loop counter clockwise. If both loops are clockwise or counterclockwise, it's more uneven than a flat track.

      With the number of track pieces in these layouts, you should install two sets of jumper wires directly from the track piece where the power supply connects to the track. The two sets of wires should be connected to points left and right from the power supply about a third of the way around. The middle third will be between the two remote connection points.

      Jumper wires connect from a track piece (usually near the transformer connection section) directly to a remote point on the track without going through the many track joints. When track power goes through a joint (esp the press fit joints of sectional track) there is a power loss (voltage drop). A wire connection directly to a remote point on the track eliminates the power loss of the joints to that point. Technically, the most voltage drop now is about halfway between each of the jumper points, and is much less than the maximum voltage drop of an unjumpered track.

      You can buy premade jumper wires with metal tips, or just use plain stranded wire like paired speaker wire and strip a couple of inches of insulation from the ends to make good contact inside the rails. There are big spaces under the track where you can stuff jumper wires into the rails, and maybe secure the wire in place with tape or hot glue. With a digital track you only need to be careful about connecting the same rail with the wire (positive to positive, negative to negative) instead of worrying about also connecting to a specific lane. With a non digital track, each wire must be connected to a specific lane at both ends, and must be connected negative to negative or positive to positive. With a non digital track each set of connections should be four wires: Lane 1 pos, Lane 1 neg, Lane 2 pos, Lane 2 neg.

      For easier maintenance I would connect the jumper to the plain track piece adjacent to the switch or the transformer connection. You're unlikely to ever need to repair/replace a piece of plain track, and a difference of one track piece in either direction won't matter much.

        Don't know how well this will race, but it looks cool and I think you have the parts. You may not have enough straights.

        Will probably race better with the cars beginning the long straight from the long R4 curve instead of racing into the long R4 curve and slowing for the following hairpin. Layout could be mirror flipped if you want the cars running down the long straight in a particular direction.

        Clearance on the overpass may be tight unless the elevation is cheated somewhere. 1/24 cars would be very tight.

          I'm almost done the table. Will be adding the facia, 'grass' and bolting it together this evening. Will experiment with all your ideas and report back. Once we settle for a design, we'll think of a theme. My son wants to do an Italian village/countryside them. Oh and I have to mount a TV somewhere for the AppConnect. Fun times!

            All of these designs for the available space are great. I REALLY like this last one though. Thatguy, you are the king of well thought out track design.
            The addition of the R4 curve makes this a fast track.
            I can see 3 areas that would work for a pitlane [any of the straights that are at least 4 straights long].
            And if mirror flipped L to R, it leaves an option for a curved lane changer going into the R4 curve. Also, as Thatguy alluded to, the R4 gives the ability to build up speed on the curve heading into the long straight [effectively making the straight feel longer than it is, and gives enough time to look up at the monitor for a second without crashing]. To me, this one looks like a whole lotta fun

              You'll probably find some inspiration for that in Luf's old Targa track thread, here.

                I was thinking the same thing, Paul.

                The Targa Florio is a classic open road sports car race through Sicily, ended around 1975. No guard rails, right past front doors in little towns. It looks crazier than the Isle of Man TT motorcycle race, and the scenery is jaw dropping. If he's never seen this, it will blow his mind.

                  I love it!!! How perfect. My son is all over it. He's more interested in building the scenery than the track. Having the buildings directly abbuting the track, makes it so much more interesting. Also, the imperfect geometry of the buildings will make our mistakes look like design choices.

                    Yeah, that was a fascinating look at the Targa. I enoyed that fabulous mini-movie in the middle!

                    I just checked, and it appears that Luf's website is still being maintained, so google oldslotracer and you'll find some great content there, too.

                      Remember that you need either guard rails or clearance to swing the tail around corners, even without outside border pieces. A standard Carrera border is 10cm/4in, which is appropriate for big 1/24 cars.

                      Don't forget to do the graffiti on the buildings and the roads. Big white paint pen on the road.

                      "Nino" is Nino Vaccarella, local hero.

                      Forza Ferrari, Forza Bandini, Go Gurney, Porsche Kaput . Or modern drivers and cars.

                      The overlapping V symbol is like "viva"

                              Track update! Dry fit the facia to see what it looks like. Thinking I may want to give it a few coats of lacquer to prevent slivers. The tables are amazingly stable, given I used 2x2's for legs and 2x4's for supports. I will bolt the tables together tonight as well then test some lacquer applied to a piece of facia to see how it takes.

                              The green grass mat is temporary but I really don't like how its shiny under the light. I do like how it stays in place nicely with the rubber backing though. Should I go get some carpet like Frogman did?

                              I'll mount an old 32" flat screen on the wall adjacent to the left side of the table for Smartrace. Any thing else i should consider at this stage?

                                Higher. That's low enough for cars to flip over fairly easily.
