Thanks Dunny , it looks like i have to be scotty of the starship enterprise to work this out .
I still don’t understand it , but thanks

Apologies in advance if I'm just repeating anything that has been said in earlier threads on this subject... but the LGB 1015 pair is not an "active" electronic device, it doesn't contain any kind of switching element or fancy electronics - under the black cover is simply a set of diodes that prevents the "permanent short circuit" effect of a return loop (where the positive rail meets the negative rail as you trace the circuit round the loop).
The 1015 is designed for analogue DC operation with a normal DC controller, and is not automatic in operation - while the train is in the loop (note that it can only run round the loop one way), the operator must reverse the polarity to the tracks, either with a switch or by quickly reversing the controller knob. The loco will then run around and exit the loop. No extra wiring is required for the 1015 to do its job, so I don't know what the black wire is for in your example... maybe it was added by a previous owner to connect to a reversing switch or something?
To operate a reverse loop automatically, with no operator input, you need an actual electronic reverse loop module such as the LGB or Massoth one, but these are much more expensive; the 1015 was a simple low-cost option for doing basically the same job, but while also needing some manual input from the operator.*

* PS: there ARE ways of connecting fancy bits of LGB switchgear to the 1015 to make it operate automatically if you really want to, but it can get a bit complicated...
