Re: Auto Reverse Segments in DCC

Wouter,

Thanks for this morning’s confirmation.  I’m pretty confident I’ve got this AR thing worked out — at least the basic principles.  Of course, the devil is always in the details in implementation — like the lighted vs. unlighted cars, or plastic (ugh) vs. metal wheels.  

 I had also posted (below) my assumptions related to operational limitations imposed by the presence of a turn out within the AR.  That limitation was to “avoid having a train cross the ‘AR gap’ at the turnout while another train is crossing the AR gap at one or the other of the two ‘ends’ of the AR segment.”  

May I assume from your silence that you also agree with that precaution?  

Thanks for your cogent advice and guidance.  No need to post a track plan.

Given this limitation, my lengthened AR segment will now include a turn out.  I assume that, properly insulated, the only operational limitation the presence of the turn out presents is to avoid having a train cross the “AR gap” at the turnout while another train is crossing the AR gap at one or the other of the two “ends” of the AR segment.

It matters very much. Fatally, for too long trains. Nobody would feed the interior lights off just one axle, and as soon as you have more than one the die is cast.

Thanks John. 
I do understand and agree with your explanation.  Sounds like that is the basis for Wouter’s "99% of the time" assessment. 
Query, in your view (and for purposes of Wouter’s 99% assessment), does it matter whether the cars (passenger) are lit?
