DCC neophyte
Posted by pdansalvish on Wednesday, November 27, 2013 6:00 PM

One thing I do not understand from a DCC wiring is the following. The bus leaves the command station and goes around the track.  Where does it terminate?

It stops where there is no more track, or anywhere you want it to.  Althought some say it is not a problem, the bus should not be reattached to itself to form a loop.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

I just attach my last feeder to the end of the bus wire. That solves the problem of what to do with it.Laugh

I run my bus in pairs to close to the end of the layout bench, often in two opposite directions from a T-connection with the DCC controller in a central location.   Where the bus wires end, I tack them up out of site and about three inches apart for extra security.  As Batman says, you could very sensibly place a pair of feeders at the bared tips. 

There is no need to cap them, put a snubber on them, or to make the wires long enough to double back and hook up to the same terminals from which they started their now very long journey.

I use terminal strips everywhere I make a connection, so I don't have any loose ends to worry about.

it's  wired just like the power in your house, a (usually) black and white wire runs from your circuit breaker box to each side of every the outlet on that run (bus).
