@DJM posted:When running a Buss wire does the wire go around the layout to be connected back at the transformer or terminal block post in a loop OR could the wire just "dead end" somewhere?
I believe that full loop buss wiring works great with anything and everything, EXCEPT.............. MTH's DCS, where dead-end buss wiring (a.k.a. "Star" wiring) is recommended.
This based on a lot of reading I have done. Admittedly, I don't have any experience with Lionel's or MTH's digital systems. I do have plenty of first hand experience with conventional and DCC systems, where absolutely NO problems are experienced with full-loop buss wiring, that I am aware of.
