Isolate the complete reverse loop totally from the layout-

Go buy a Digitrax’s AR-1 Reverser-

Read the instructions so you can understand the operational theory and get it wired correctly

There are 4 wires on this unit

Hook 2 of the 4 wires to the layout and the last 2 wires to the loop-

Set the current reset (IF)needed, mine worked just fine out of the box.

Run your trains!!!!!

NOTE- Your engine/s or LIGHTED passenger cars must be ALL IN or ALL OUT of the loop to operate properly
Un-powered rolling stock can hang over the isolated loop section.
I hope this helps if someone explained it to me this way it would have saved me weeks of stress and frustration. I hate reading a whole book just to find the needed paragraph of info. I wish you the very best ~AlanC.

You should be able to access earlier responses to reverse loop wiring help from myself and others by using the ‘search’ feature in this blog or elsewhere on other model railroading Internet sites (there are many).

There are inexpensive (about $25) relays out there that will handle the polarity issues for you automatically that are very easy to install (also described in this site’s blog search engine). Just be make sure that you have electrically isolated BOTH rails at EACH end of the reversing loop section to prevent short circuits, no matter which approach you use to solve this issue.

At the risk of stating the obvious, you won’t be able to run your trains within the reversing loop section until you have completed the necessary wiring for the loop.

Hope this helps,
