I am getting ready to wire the return loop on my lower staging. I have done "simple" reversing loop wiring before, but now I am using a "wiring bus." Do I wire the reversing module in line between the main and the isolated bus wire?

Or can you give me a suggestion?

Thanks

Autoreverser

You need an autoreverser like these listed at MRH Sponsor Litchfield Station. Ideally you'd have it on it's own booster and thus it's own bus, but you can split out the bus from one of your other boosters to it.

Since the reverse loop is totally isolated from your other wiring you can pretty much wire the autoreverser off of whatever bus you want.

I'm using a PSX-AR myself and haven't had any issues with it.

You wire the reverse module  so that it gets both rail B and rail B on one side from the main  and the otherside has  rail A rail B going out  to the reversing section.  If you have only one reversing section you can get and AR1 from Digitrax; at $24.00, the least expensive, simple. Not the best out there but still should do the job.  Just pay attention to the gapping, as you are certainly aware, of both rails.

I got this from the link

I got this from the link provided above

    "On long reversing sections to few track feeders from the auto reversing unit can prevent enough current on that side. Relying on current through the track itself, particularly rail joiners, is not wise as rail joiners are notoriously poor conductors of current."  

So I guess I am going to write the bus, but when I do be sure to separate it from the "normal" part of the bus. The reversing unit is wired as the "go between" the bus wire and the bus wire of the reversing section.

By the way, great link. Thank you.

Indeed, nickel silver track is not a great conductor and rail joiners by themselves are terrible, IMO.  Soldering rail joiners will help and feeders to every 6 foot section of soldered rail should take care of any poor conductivity or resistance issues with the rails.  Just my two cents though, individual results may vary.

The terms and definitions can sometimes get a tad confusing.

The ' BUS ' is the wires running around the layout comning from your power management or command station.

The ' FEEDERS '   are from the bus wires to the track itself.

The Reverser goes in parallel  on your feeder wires.  If you have multyple feeders for the reverse section (which is a good idea) then the feeders  would fan out   AFTER  the  reverser module, from the feeder side of the module.

Probably overkill on my part, but want it to be clear in my head also.

Could not agree more with the

Could not agree more with the affor mentioned statement. I will be implimenting this plan as soon as I can.

thank again

DCC reverse loop wiring was covered in the Mar/Apr MRH

Look in the March/April 2010 MRH Questions, Answers, and Tips section where DCC reverse loop wiring was covered.

https://forum.mrhmag.com/magazine-feedback-was-ezines-891776

If you click on the page thumbnail in the above link you'll go directly to the online version of the article, otherwise download the Mar/Apr 2010 issue and take a peek (or if you already have that issue in your computer, look in the Table of Contents for Questions, Answers, and Tips)
