Moonman, just read your advice and humbly (honestly) disagree with comment #1 about insulation pins. The general rule, as I understand it, is to isolate each power connection to the track from all others.
If only 1 'lockon' is used then no insulation pins are needed.
Assuming more than one, one would need at least 2 per 'loop'. The theory is, again as I understand it, an engine should NOT receive a command from more than one source. So if 2 lockons (for simplicity sake of conversing) are used in one loop, say one on the left side and one on the right side, an insulation pin should be put in the center rail on the north side and another one in the center rail on the south side thus isolating the left and right sides from each other guaranteeing that the engine only receives its command from the connection where it is running in.
At least that's how I have always interpretted 'the rules'. My apologies if I am misspeaking.
