Hi Max, the layout will be 1 foot wide around 3 walls of a 10x10 room in 2 layers with a helix and one wall will be 2 feet wide for yards and staging

I like your idea for the sub busses in the detected sections -- and I think soldering to the busses is the way to go

However the answer to your BD -20 question is addressed by these two sizes  – tap a 14 or 16 ga. wire as a sub-buss off one of the  main feeder wires, run this sub buss through the BD-20  and connect   the all track droppers  for one rail of the detected  section to it. Droppers for the other rail can go to a sub buss off the other main feeder wire, but of course no BD-20.

And don’t forget to insulate the detected rail from the adjacent section  rails.

If you are going to use a lot, a proper tool is recommended or the “connected forever” may be more hopeful than real.

And BTW just how big a layout are you contemplating, 10g main feeders is massive overkill for most cases.

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.

Re: Kato Switches and DCC

Daniel Thomson
 

Vince,
Let's simplify a few points here.  First, Kato turnouts are well documented on how to insulate or power the rails in their packaging literature.  Second, the turnouts require their own D.C. power supply to throw them.  Third, they are NOT twin coil machines... explanation?  Twin coil are controlled by three wires, D.C. coil are controlled by two wires.  Mike Fifer of Fifer Hobby Supply has a good explanation of the difference and how to wire a DPDT (double pole double throw) momentary contact switch to control each one.  "How to Make Kato Turnout Controls" is a good websites search phrase.
This assumes you want to wire up the turnouts with traditional switches.  But, what if you want to use DCC to throw the turnouts?  There are many different brands of DCC interface Turnout Control Boards.  Some are for stall motor machines and some for twin coil machines.  The latter can be wired for D.C. coil types like Kato.  There are single unit board's but there are more economical board's that may control up to 8 turnouts.  A member of our club is up to turnout #90 off twelve board's so far.  Each one has a small number board near it.  He hits "Select Accy", the turnout #, and 1 or 2 for the direction... and the turnout throws.
It is NOT necessary to have Turnout Control Boards of the same brand as your DCC system.  Feel free to shop around.

Hi Vincent,
I would not use single pole switches at all. While there may be a way to hook them up, it is too simple to foul things up.
With a DPDT switch, the DC + and - wires go to the , and the two wires to the turnout go to the two center contacts. The two ends are hooked together with a criss-cross, or X.
When you test, if the turnout goes the wrong way when you hit the switch, you can reverse the wires at the turnout, or at the center contacts of the switch. If it would be easier, you can buss all the + sides together, and all the - sides together from the DC supply. I run my DC supply at 14 volts. Since it is just a momentary connection, it provides enough energy to move the turnout quickly.
Although it is not too helpful, I can post pictures if you want.

Hi  Vincent,
Just make sure that they are center off, momentary. Otherwise you will destroy the Kato coils.
The switches should not be very expensive. I have the miniature ones because of the size of my control panel. They were less than $2 each. I am guessing that they may not have increased very much.​ Simple to wire, just be careful soldering, because it is close quarters..

Hi Vincent,
As I have said in an earlier post, I use DPDT, momentary, center off switches on my Kato HO turnouts. The Kato turnouts are of a "Twin Coli" type, and it works fine.
You can also use DCC, but it gets more complex, and you have to be sure you have the correct interface boards, as ones used for Tortoise will ruin the Kato coils.​

As for why use one or the other, it is strictly a matter of choice and the reasons for and against degrade into a never ending discussion that no one ever comes out feeling good about. So, evaluate what you want to do, and how you intend to do it, then press on. Both approaches work. The fun and complexity of one over the other is in the eye of the beholder..

Hi Vincent:

 

Yes, Kato switches (turnouts) can definitely be used with a DCC system. Throwing them manually is no issue.

 

The turnouts are solenoids that are operated by reversing polarity. Thus you would need a DPDP-Center off, spring operated toggle switch. It  must be spring operated so contact is made only as long ads you hold the toggle in the desired position. This must be brief as too long a current flow will burn out the solenoid.

 

The Kato proprietary switch is not required, but it is probably the safest for operating their turnouts.

 

You can also use DCC decoders to operate the turnout solenoids.

Question; can Kato DC switches be used with a DCC system? I'm planning on throwing the switches manually. That leads me to my next question; can I throw the switches using a single pole or double pole switch (which one)? and/or does Kato require their own propriety switch to be used? 

 

Thanks guys I always get good advice on this group.

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.

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.

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.
