I have a 12-track staging yard; in order to implement detection, I need to run one bus wire for each track's front rail, having run that wire through both an on/off switch and a current detector. All is fine there.? However, respecting the second bus wire for each track back rail, is there anything that prevents that wire being common to several/all of the tracks?? I.e. could I wire, in the extreme, all 12 back rails to one common bus feed?? I had already assumed I'd run a wire for each track, but it occurs to me that that may be excessive.
Comments?
