Re: Hopefully starting new layout

David Heine
 

On my layout (27' X 32') is use #12 AWG for the main DCC bus. #14 AWG sub-buses are used to divide the layout into electrical sections. I feed each sub-bus with a disconnect switch, for easier troubleshooting. My sections are towns, yards, mainline sections, etc. I use #22 AWG drops to each piece of rail. If the drop doesn't reach the bus, I usually use a piece of #18 wire to bridge the gap. I don't solder under the layout. I either use terminal blocks, or the Scotch "suitcase" connectors. I use both the 905 and 567 Max mentioned. I have installed hundreds (thousand?) of these with hundreds more to go, so I bought one of the 3M crimps tools when I first started. Layout is Sn3/Sn2/S, so the loads are similar to HO. Rail size is mostly Code 70 and 55, which is why I use #22 drops.

Tim,
No automatic soldering iron but there are Insulation Displacement Connectors (IDCs).  These are a crimp on connector that slips over the buss wire and accepts the feed wire along side and has a metal bridge that is squeezed down, displacing the insulations and jumping a connection between the wires.  At about one inch long and applied with a squeeze of pliers this is a solid, secure connection.  They can be purchased by gauge of the main wire and gauge of the feeder wire.  No wire stripping, no wire twisting, no hot irons.

Hi Tim,

I am also a firm believer in soldered connections to the bus.  Be sure to stagger your connecting drops to the bus.  In other words do not allow your connections the possibility of shorting together.  Also I would highly recommend this kind of wire stripper https://www.harborfreight.com/catalogsearch/result/index/?dir=asc&order=EAScore%2Cf%2CEAFeatured+Weight%2Cf%2CSale+Rank%2Cf&q=wire+stripper
This type is available from many suppliers.  This stripper actually "pushes" the insulation apart to allow your jumper to be soldered.  This is illustrated at minute 1:40 on this video How To Use The Automatic Wire Stripper
This will save you a ton of time.  Good luck.

HI guys -- im hopefully starting a layout this weekend with a test module -- the layout will be made of 1x2 foot sections (for ease of handling) -- my thoughts are 10 or 12 gauge wire for the power bus, and ideally 20 or 22 gauge risers to the track -- every section to have a riser on it to ensure good connections. 

I'll probably strip back sections of the bus, and solder the risers to it again to ensure good connectivity.

What else should I be doing -- I am planning to use NCE system, and I really want to get this right the FIRST time

New group just to sell DCC Stuff

Dennis Cherry
 

New Group on Groups.io for DCC only


I started a new Groups.io called DCCSwap.

This site is only for DCC/LCC related items. Read the conditions, very generous.

The groups will have minimal monitoring but the first 2 posts will need to be approved before being listed, then its up to you.

I will check in and if something does not comply, then action could be taken.

Read the conditions, it will spell out the rules.

All,


As you may have heard from others, groups on Yahoo are having problems and are moving to Groups.io.  I will be moving the Wiring for DCC Q&A Forum as well.  I'm hoping to do this within the next month.


I am in the process of learning about groups on Groups.io and setting up the new Q&A forum.  It is my understanding that if you want to be a part of the Q&A forum, you won't have to do anything - your membership and Yahoo settings, like whether you receive individual emails or digests - will be transferred.  I also plan to notify you when the forum is moved and I will change the link in my website so that new people can find the forum.

Hi Allan,

If it really works out that seamlessly, it is time to take my hat of to IT people for the first time in a very long while. So far, I've only heard good things from those who switched, but it looks like yours is the first group I'm on to take the plunge. Best of luck - hope there's not too much admin work involved in setting it all up.

Re: Reverse Loop inside another reverse loop

Steve Haas
 

 

Ed Robinson asks:

 

“I have a reverse loop that is controlled by a PSX-AR and I have added a quarry at the end of this loop that is controlled by a wye.  I understand that this creates another reverse loop but that I can manually control the turnout at the end of the wye using a DPDT switch. My question is: what does this do to the PSX-AR sensing functions - with or without another loco in the original loop?”

Ed,

 

It's a bit difficult to answer this question without knowing the lengths of the various tracks, and how you intend to operate engines/trains in that portion of your layout.

 

Having said that, this can be done with only one PSX-AR.  There are several ways to wire this:

 

  1. Control the polarity of the stub end of the wye with contacts on the switch machine for the turnout that controls the access to the stub end of the layout.
  2. Use the PSX-AR on the reversing loop. Beyond the gaps to the wye the wye tracks and stub can be controlled the same as the track entering the reversing loop – the PSX-AR will align the polarity of the reversing section to the main track out side the reversing loop or the stub end of the wye as needed.
  3. Extend the mainline block through one side of the entrance turnout, through the first turnout to the wye, that side of the wye and the stub track. The remaining portion of the reversing loop and (optionally) the other leg of the wye.

 

There are variations on most of those options depending on which makes the most sense for your track plan and how you intend to operate the area.  If I were a better artist I’d draw out some examples for you. 

 

Just remember, the track that creates the ability for a train to reverse itself isn’t necessarily the section that should necessarily be powered by the PSX-AR.

 

Let me know if you need more help with this!

 

Best regards,

 

Steve

Re: Reverse Loop inside another reverse loop

Ed
 

Thanks Don & Steve. I believe I understand each of your explanations but a short description of operations is in order.

This is a short reverse loop because it only leads to a small quarry where one or two cars would be loaded. Movement of the cars within the quarry is done with a small switcher. Cars would be delivered to/from the quarry from the mainline using mainline locos so they would cross the wye and enter the quarry, drop off/pick up the cars, then exit the quarry via the wye. It is also possible for the quarry switcher to move the cars to/from the quarry by crossing the wye and drop off/pick up on one of the mainline legs of the wye. So, one of my questions is: can you have an operating loco in the mainline reverse loop and at the same time have the quarry loco move across the wye to move cars? If not, then a solution is to never have the quarry switcher cross the wye but this limits my ability to move the switcher to somewhere else on the layout - the engine shed in town for instance.

Re: Reverse Loop inside another reverse loop

I agree. Post a sketch showing the track layout and things you name so we can mark it up and send more thorough suggestions.
But... any loco that stays inside the A-R controlled section while another loco/train enters/exits over A-R/main boundaries will not be affected by a change in A-R section polarity. Trouble occurs only when two different A-R boundaries are being crossed at the same time. The polarity of a wye stub can be selected by the position of the last turnout leading up to. If the sub-bus feed for that stub and turnout happens to be an A-R section controller... so be it.

I think I have the new Q&A forum ready for a few brave soles to try out.  IF YOU ARE CURRENTLY A MEMBER OF THIS FORUM, DO NOT JOIN THE NEW GROUP.  THIS WILL BE DONE FOR YOU AUTOMATICALLY.


Please do tell your friends about the new group; especially those who were waiting for the new group before joining.  Ask them to join the new group.  Once I am sure everything works right, then I will move everyone in the Yahoo! group to the new Groups.io group.  The messages in the Yahoo! group will also move at that time.  I'm hoping to do this in the next few weeks.

Re: Reverse Loop inside another reverse loop

dvollrath@...
 


I certainly does, Ed. Thanks.

Isolate both rails between turnouts 1 & 2 and 1 & 3. [easy to do using 4 insulated rail joiners at #1]
Wire the entire turnout #1 and the Quarry rails at the point end of the turnout through a DPDT switch, OR a 2nd PSX-AR, to switch power according to the position of turnout #1... but the INPUT side of the switch should be to select power from the main reverse loop rails.

If turnouts 2 & 3 are of the power routing type, add an insulating joiner on the frog rails between them.

Then when a train flows through either 2 or 3 to get to/from the Quarry stub it will automatically be at the correct polarity to exit/enter from the main reverse loop. If 2 and 3 are set to bypass the Quarry it doesn't make any difference what polarity exists on turnout 1 or the Quarry stub.

A loco already in the Quarry or even in the process of entering/exiting via 1, 2 or 3 will see the polarity quickly flip if there is a polarity change of the main reversing loop. This should not interfere in any way.

You can still get short circuits, and derailments, if both turnouts of either desired path are not set up correctly before attempting to run a loco through it. But that is operator/engineer error.

Yes you can. Building a DC layout does not force you to change how you control turnouts.

How you control turnouts is independent of how you control trains.

Re: Manual Reversing loop wiring

Kurt Konrath
 

Others may have better idea but if you isolate the loop track which would be needed in future anyway. You then simply add a manual toggle switch. A Double Throw Double Pole DPDT center off style (on/off/on) and cross wires on back with center leads going to loop track

Then you flip the switch as needed!

Re: Manual Reversing loop wiring

 

What sort of turnouts control the loop.  If you are already using a toggle switch you can get one with two extra poles and directly control the polarity and the aligning switch at the same time.  No need to purchase expensive electronics at all.
