Anyone used shielded cable with success? I have the turntable tracks to wire and instead of making twisted pair wire I have a ton of single conductor shielded wire from the aircraft industry I would like to use. I'm using a rotary switch to select which track to select; from the switch to the tracks is where I would like to use the cable. There will be one common ground near the switch and I'll be using filters at the output of the TIU and one filter at each track.

Hi Gary, I bet the shielded single conductor wire would work just fine. It may be a little over kill for what your doing.
If I may make a suggestion, I would ground all your shelds at one end of the conductor, or wire. Do this at a central point, lets say a terminal board.
Like I said I may be going over the top here but when I worked in telle-communications if we terminated our shelding at both ends of a T1 twisted pair there sometimes was a ground loop created that caused noise to loop back on it's self.
I assume you are using DCS so I'm a little apprehensive of how the slope of your conductor acts up aganst the contacts of the rotary switch.
Like I said I could be over thinking this whole thing but to be on the safe side play with some quick circuits through that switch to see what happens. I would hate to see you spend alot of hours doing wiring work just to have a ton of problems with it.
Another thought would be to make sure that both conductors in your circuit are the same length.
Let us know how it works out.
Good Luck,

I'll find out today as after taxes I'm going to start wiring. I have this stuff so I might as well use it.
Thanks Mario
I have each turntable track wired with a single conductor, unshielded, running from a small control panel, which has a separate toggle for each track. This way, I can leave one or more tracks powered to charge batteries in shut down locos.Common ground running from track to track.
