4.2. 2-Conductor Track System:
If the manufacturer of your digital command station permits a common layout ground
(“brown” or “J”) one rail of the 2-conductor track has to be isolated at the cross over
joints from one to the next booster electrical circuit.
If the manufacturer of your digital command station does not permit a common layout
ground ( „brown“ ) both rails have to be isolated at the cross over joints .
