I am re-doing my layout and making it much larger with a lot of turns and switching. I plan to use both DCS and Legacy systems. I know that the DCS instructional video indicated that I may have a problem with bus wiring; but bus wiring seems so much more efficient.

Does anyone have experience with wiring a large layout with bus wiring and DCS.

While star/home run wiring is preferred, DCS is quite tolerant of other wiring schemes, including buss-type wiring. However, not all buss wiring schemes are equal as regards DCS and separate Hot wires are generally required for the best DCS signal strength. If you want to maximize your DCS experience, I strongly recommend star wiring. That way, little is left to chance.

I am still relatively new to this hobby; but I believe start wiring is where you connect both the hot and ground wires from  your transformer to a relatively central area of the table; and then you run all the drops from the track to that central area. You can do the same for your accessory connection of your trtansformer to hyour various accessories.

trainrat:  My layout was built in early 90's, before DCS.  It used 6 "transformer handles/power districts", 70+ blocks each fed througha toggle switch, each block fed vis 14-gauge wire, and a 12 or 14-gauge (I forget which, bare wire which loops completely around the layout (both ends connected to transformer U terminals--2 pw ZWs & 1 KW).  Every accessory and all track is grounded into the buss.

 

When DCS was released, a Z4000 was added, & 2 TIUs were slipped into the circuits from the transformers that fed the areas on the control panel.  In fact, the ground is not fed through the TIUs, but all black outputs connect to a single wire that goes into the buss.  No black input terminals have anything connected to them.  Reason is that I didn't want to chance overloading a ground circuit in a TIU.

 

Light biulbs on some sidings.

 

I've been running happily ever since.
