Re: Where to isolate on large loops and wye


Steven Tobias,

AR refers to “auto reverse” — either a segment of track controlled by an AR device or the device itself, which automatically senses the incidence of a short circuit as the conductive wheels of an engine or car pass over the “gap” between two segments of track of opposing phase/polarity.  The device automatically switches the phase/polarity of the reversing segment of track to match that of the non-reversing segment, averting the short before it can trip the circuit breaker.

Yes you can attach the output wires of an AR until to more than one place within the AR section of track. May help bypass misc poor rail connections, etc. Just make sure you have a consistent rail polarity.
