Turn each section of track over and push the end tabs together with a flat bladed screw driver, you just need to push down on the silver metal tabs, so 8 tabs altogether on each section of track.
Don't go too mad with it, but give them a firm push, the tabs may bend a bit and leave an indent line from the screwdriver but this OK.
This works with Scalextric track anyway, not sure about SCX as I have never even seen it!.
After doing this to all my 200 odd pieces of track I never get power losses anymore, and for Scalextric Sport analogue setup I use 2 power supplies, one for each lane.
Also make sure the track is also flat and joined straight at the joins the best you can, otherwise this will cause power loss too.
