 If he makes a second one. As drawn only 1 reverser is needed.

I think we all agree with that.

Each loop should have its own reverser. 

I'll second that.  Yes

Although it's clever to use the same auto reverser for multiple sections, I would caution against it.  Sooner or later, perhaps when operating the layout with a friend, you will put yourself in the pickle of trying to manage both reverse loops simultaneously and all this wonder-tech will not cut it.  You will end up using the old 5-DCC controller and pulling the train out of the loop with your fingers.  Each loop should have its own reverser.

Welcome to the Forum.  Lots of good info and help here. Smile 

The link below (see "Reversing" part way down that page) does a great job of cover the basics, including some typical layout examples if you would like to understand further.  Some of the examples probably relate to the options you may have.

I'll second the recommendation to examine options to create dual reversing ability to handle from either mainline direction.  I have a dual reversing setup on my dual level HO 5'x9' layout, which is a sorta classic "folded dogbone".  I used the OG-ARs (only $32 and work fine with my NCE) on my loops, choosing to use one on each.  Tony's Trains has some very helpful folks who can help you choose basis the nature of you layout, DCC system being served (if that matters) and number of locos being run at one time.

Ideally, the reversing section should be longer than the longest train you plan to run through it.

You do not need 2 reversers, one will do the job. And as already posted insulate both ends of the reversing section

Yes. And, a single AR can be used to reverse two (or more) entirely separate isolated independent loops located anywhere on the layout. The caveat is that multiple trains cannot enter multiple loops simultaneously.

Insulators are required at both ends of both rails of the blue section.

Take a look at the PSX-AR for your auto-reverser.

Yep, that will work. The problem with that track design, though, is that after the first reversal, your train will be stuck in that direction.

I have the right to remain silent.  By posting here I have given up that right and accept that anything I say can and will be used as evidence to critique me.

Reversing Section - DCC wiring
Posted by Kyfoto on Friday, April 7, 2017 7:14 AM

I'm wondering in this layout for DCC where I would need to insulators and if I need to use to auto reversing devices, one at each end of the reversing section or whether I could just use one in the center of the reversing section.

revesing layout

I'm brand new to model railroading and appreciate any help you can give me.

Thanks,

Dave
