Power Bus system

I am confused regarding the Bus systems people use. I have looked at a few other threads and its confused me more.

Anyway. if I explain what I think a bus system is then could anybody enlighten me as to weather or not I am correct?.........

Basically cable running every couple of metres soldered to the edge of each rail and constantly going around the track, starting from track source? I did a search on the net for bus kits and one DCC kit I saw involved crimps and all sorts of stuff, not what I expected.

(wires in photo not soldered to track - just placed for photo reference)

The wire I am using is the same specification that comes with DCC sets. I have stripped the ends of the cable to approx 10mm and tinned them to stop them spraying out.

Any help will be greatfully appreciated.

Also agree, and Rapid part No. 86-0390 makes stripping the insulation back very quick and easy. Although they're normally used for stripping from an end, they work just fine along the length of a wire, parting the insulation enough to solder the dropper on.

The ideal to aim for is one dropper for every piece of track so that you do not rely on track joiners which can cause problems long term.

Flexible conductors are very much harder to strip along their length. It keeps flexing then the knife digs into the soft wires and fractures a few conductors so you end up with 2.5 cable reducing it to around 1.5mm if you're not careful.
It's even easier with "automatic" wire strippers. See earlier in the thread. They cope with solid and stranded.
