That looks good, makes a nice connection and you still have portability. I used to just fold the tails over and staple them together underneath. But then you have to take the staples out to get the track apart. What I do now is put a dab of silicone in the slot that the braids run through the joint in. Then let it dry completely. Because the braids are touching together already, the silicone makes a pressure point to ensure a good connection. Then the braids are individually stapled to their corresponding track section. In this way I can take the track apart without disturbing the braid at all. In the morning the first thing I will do will be to silicone all the joints, then with the track in the basement while the silicone is drying I will wire the track.
I used this method for commercial tracks too but since most of those tracks would stay in the same place for a few years I also stapled the braid together underneath. And taps were made by crimping eye connectors to the braid tails and the tap wire and screwing them together to the bottom of the joint block. In some cases I left the tails long enough to go to a board with individual bolts for each tap. Just depended on how elaborate the wiring was going to be. For this little track the control system is fairly elaborate but the wiring to the track is going to be fairly basic. The runs in front of the drivers will connect a positive for each lane and I put some braid drops on the over bridge section for an additional negative tap.
