From what I am reading, the WTIU "may" out soon. Question: With the WTIU having wifi capabilites, will STAR wiring still be required to prevent power drops around a layout? Mine layout is 12 X 8.

Thank you !

Bus or star wiring and power distribution is required because rails and track joints have resistance. We use copper wire with low resistance to distribute power and avoid dead track spots from bad joints carrying current to the train. Again, you use star or bus wiring to distribute power to the train, because our track systems of typically short pieces of track, connected together with pins or track joiners that can loosen, along with the linear resistance of the rails being a metal other than copper is why we need distributed power. It has nothing to do with DCS or the control system.

WIFI is how you send a command from your 3rd party phone or tablet to the WTIU. It has nothing to do with your train, your train is not wifi, nor does it get power wirelessly.

Actually, the choice between bus and star wiring indeed does have to do with the DCS signal!
