With each piece of track, turn it over and using a flat bladed screwdriver, press all the small silver retaining tabs down firmly and this will certainly help, ys I had Scalextric SSD and once I did this I had zero issues and NO power taps were needed on a 30 metre track. 

Power taps, power taps, power taps is all I see and hear and power taps are not ALWAYS the answer, these power tap posts need to slow down considerably and stop making considerably more work unnecessarily for people.
