DCC wiring

[tomtrain7]

I have a very DCC question. I have a small layout with one tunout off of my oval going to a deadend . Do I need a reversing loop with my E-Z controller?

You won't need anything additional from what you have described -- you don't have a reversing connection if the only spur is a dead end.

You have a simple spur is not a reversing loop.  I'll add a bit of background so you can understand how to distinguish a reversing section.

A reversing section exists when the loco (train) can traverse track and end up traveling on track opposite to its former direction on the original track.  When this happens, the track polarity (if you trace, say, a DC positive rail) can come back to the original track and run into the negative side.  This would create a short unless isolating gaps in the rail joint are provided.  The same is an issue with DCC, even though it has a different kind of "polarity" than DC.

Reversing sections are created typically in three ways.  If a turnout has track that loops back to itself, you have a reversing loop.  Also, a turntable can create a reversing section by turning 180 degrees and lining up again with the polarities mismatched.  And a "wye" consisting of three turnouts connected together as a sort of triangle creates a method of turning a train around (on the extended tracks) such that the train entering can end up routed back to the original track in the opposite direction.

I'd suggest you have a model train wiring book, there are good ones available in a hobby shop or here in the Kalmbach store. Or, utilize one of several websites offering similar info.
