Wire, Wire, Everywhere

Yep...just finishing up my 5000 feet or so on our layout.  It's nuts, isn't it?

But the future is coming.  There will be a day where you won't need that many wires.  Several folks on the forum here are experimenting with different battery techs, radio operations, phone-based apps that require no juice in the rails.  Surely similar tech will follow to get the juice out of the switches and accessories to a large extent.

In a generation, people will think it's crazy that we spent more half our time on a Trian set climbing around under a low table risking back and neck injury.

Less crouching = more fun as far as I'm concerned.

Good luck!

Can you say spaghetti?  😀😉😂😆

Did someone say wire?

I was into about 3000' of wire when I received my first battery powered engine.

I had been laboring for a long time trying to get stuff wired while getting discouraged.  Due to the complexity of scores of turnouts, sidings, blocks, sub panels, etc. it was never a matter of attach two wires and run trains.

In the midst of it all a friend of mine offered some advice, "Just get a battery R/C unit and have some fun while you are doing the wiring".

Wow!  My RR was actually, finally FUN!

Well I wrapped up wiring the primary routes but all my minor branch lines never progressed beyond the initial feeder drops.

I have enough battery powered motive units that I may never run another length of wire.

This is the bottom of a 4' X 13' peninsula with what including the connecting module would normally be 14 blocks and 12 pair of points:

Note the empty wire management holes...

Battery powered Geeps, K4s, John Wilks,  RDCs and Doodle Bugs will service this town.

All hand thrown points:

The initial module is also wireless.

The padded handles were for carrying early on when this was a show display.  I recycled my old display modules into today's RR.

I actually shuddered in my seat just looking at this.

I didn't tally up the wire I used, but I've used a bunch.  OTOH, I'm not willing to give up all the cool features of my modern locomotives so I can go battery power, so I'll keep wiring stuff.

Getting sucked in and eaten alive.

John,  Smoke,  choo choo chug ,  blow down, or diesel prime mover sounds, ditch lights, running lights, marker lights,  etc are all available with wireless.

Wireless systems are open platforms to receive any companies sound and accessory decoders/features.

Folks is not wiring and carpenter skills and scenery skills part of why we love this hobby!!!

Forgot about running trains we enjoy that also just think of this great reward when we are finished with the above stuff!!! That is if we ever finish!!!

Is it just my layout or do all layouts require this much wire? I have been wiring the rails on my 16x17 layout and looking ahead is an eye-opener. I have 8 electrical blocks going into 3 TIUs.

Don Merz

Why do you have 3 TIUs?  I have one TIU for a 15x33.

Such as...?

Ron045: I have 3 TIUs because I tend to overdo everything and this is where I landed. It makes NO sense--just like 8 blocks is too many. But it's all up now and I am sticking with what I did. Possibly a wrong-headed direction...

Tom, are you offering to finance the conversion of 100+ locomotives to wireless operation?  They already run fine on powered track with full features.  As far as all those features being available, I have yet to see any of the threads here doing a full conversion that offers features I have on my Vision Line BB or Challenger.

AFAIK, battery power doesn't do anything for switch machines, signals, structure lighting, Miller billboards and yada yada--basically 85% of what needs wired is not addressed by battery power. Wiring the rails is a drop in the bucket.

Don Merz

Who needs batteries when you can have fun with wiring.  This under a friend's layout.  NH Joe

If I had to do that much wiring, I'd more seriously consider batteries!

A Wall Street based suggestion ...

As compensation for buying and installing all that under-platform wiring, buy stock in a copper manufacturing company. The more wire hobbyists use, the greater your quarterly dividends!

Like most of us, the underside of my layout has a huge number of wires. Thank God I kept good wiring diagrams! When I run battery powered locos, it all becomes trivial. I am planning to convert all the turnouts and operating accessories to wireless control. Wish I knew a way to provide power to the  accessories which will be required even with wireless control. Well, maybe a few wires are OK.  It seems inevitable that this is the way serious train modelling will eventually go, so why not start now?

I wired dual cab control like the HO guys used to do. A lot of wires, don't like all the wiring.

And I really didn't follow advice I have read over and over to keep it so you know what's what.

Rolls of wire are usually 500 ft. at an electrical supply store.  Multiple conductor 18 ga thermostat wire consolidates a lot of wiring in one bundle. IMO.

There are wire management systems.    Examples: Click on the underlined phrase to link

It's amazing how layouts eat up wire. In my former life I worked in new construction as an electrician. I wired thousands of homes in those years and an average size single-family home used between 2,000'-3,000' of wire.

Big difference is the number of different systems we need to run power for. Often 2-3 sets of wire can go to the same location- ex- a typical siding would have wire for turnouts, block power, uncouplers, track bumpers, etc. Then throw in lighting and scenery and you can total up 100' + in a blink.

I'm with Mike CT and use multi conductor cables where ever possible. I have lot's of old telephone, Cat 5, and control cables from my contracting days and they are all in use on my layout. Power drops are larger gauge speaker wire.

Bob

All the runs to my DZ-2500 switch machines are CAT5 cable, that also gives me several spare conductors coming back to my power panel.  Runs to my fascia mounted siding control switches are also CAT5 cable, they just switch control power to the relay boards on the power panel.  What really eats up the #14 track power wire is the home runs to accommodate DCS star wiring!

The CAT5 wire is a good idea. GRJ--do you crimp the ends or buy the wires pre-made? I had bad experiences trying to crimp RJ45 ends. But I am planning to use RJ45 for my signals--ugh.

Don- I gave up on trying to make up RJ45's years ago. I use punch-down blocks or female cat 5 jacks. I purchase patch cables when I need them. Simple splices work often too.

Bob

I do have the tool and plugs for CAT5 cable, but not needed in this application.

I used punch-down blocks at the main panel and the other end of the CAT5 cables are connected to the CSM2 Breakout Board terminal blocks, no RJ-45 plugs in sight.

The blank block is for the switches coming for my industry sidings and the 8-track freight yard that is yet to be built.

RSJB18--So far I am wiring on my junk box wire. We will see how far it goes. I am a ham radio guy in my other life and I have a ton of 50 ohm and 75 ohm coax here. I was wondering if there was any way to use it. But 2-conductor heavy wire is not that useful. I am using wire markers to number and label the wires. My color coding is a bit scattered but I think I have it under control--and written down.

Two things I am doing that might be useful to others are 1) I use shower curtain hangers to hold the wire runs. This keeps the wiring grouped and orderly. Many runs will ultimately go through each hanger. 2) I use junction boxes but I also use copper-clad boards segmented (with a dremel grinder) as intermediate connection points. The copper clad solders to really well and it takes seconds to add a connection. I almost wish I had used the copper clad instead of my junction boxes. But too late now...

Pix of boxes, copper clad,  hangers and tools of the trade attached.

I won't win any super-neatness awards, but I just ran the switch and track wiring through the Mianne I-Beams and labeled them so I could trace them there.  All the CAT5 cables got labeled with the switch # they controlled, and the track power drops with initials of what they were powering.

I decided not to post a picture right at the panel, it got pretty "busy" there, and might scare folks.

RSJB18 and GRJ--I like your RJ45 solutions and I will be using them. For something like the RJ45 female sockets, or pre-made cables, where is a good source? I saw some at All Electronics I think...

Don

I'd probably check with places like www.aliexpress.com or www.banggood.com, etc. for cheap bulk components.  Of course, there's also always eBay...

Doggone it GRJ, you might win some neatness awards! That looks pretty sharp to me. I REFUSE to go under the layout unless it's positively necessary. So I do nothing under the layout. Everything is at the layout edges so I can work beside the layout. It can make wiring runs a bit longer. But this thing is small--only 16x17 so I don't worry about slightly longer runs.

Don

Cat 5 for low current signal wiring along with #66 punch down blocks is the cleanest way to go.  the other end of each cat-5 cable is terminated in an 8/10 pole screw terminal block.  In addition we ran 2 conductor #18 cables to many distribution blocks under the layout for lighting.  we run over 60 amps of lighting.  The silver satin wiring is to the Custom Signals devices and there is over 5000' of that alone.

I estimate we used 1000' of #12 outdoor lighting wiring for the track power (star distribution)

we used approximately 5000' of cat 5 for signaling purposes and general distribution.  All ties to blocks at the back of the layout

2000' #18 dual conductor for lighting

And of course the silver satin which all terminate in RJ-12 connectors at both ends

You absolutely, gotta have a wiring plan.

For the track buses, I'm using 12 gauge red & black stranded wire pairs and wrapping them together with color-coded zip ties and labeling them with plastic ID tags.

Whoa George--You are the MAN! Way to plan! You have "Eastern" and "Western" power districts?  Yeesh. This layout is small--16x17. It is really all I can handle. I can't imagine building one of those huge, basement-filling layouts in the magazines. Yipes!

Don

George--looking at your wiring plan, I have easy questions. Why do you have separate wires in different colors going to the outer rails? I am just connecting my outer rails together. Also, what is that BLUE TMCC note? My TMCC base is really just "one wire" connected to the ground side of my 3 TIUs and the grounds of all channels on all TIUs are electrically tied together. I think what I have done is good enough. But I am never sure.

I'm with you here.  I have 12 x 24, and I'm sure it's going to occupy all the time I can devote to attempt to "finish" it in my lifetime.   While I can dream of a huge layout, in truth I believe this is all I can handle, and maybe even a bit more than I can handle!

Actually, there are 8 power districts .  I've split them into a Western grouping (Steubenville, OH which is on the western shore of the Ohio River) and an Eastern grouping (Weirton, WV which is on the eastern shore of the Ohio River).  The layout is 47' x 11' and, at times, can seem quite daunting.

OK, easy answers:

1. The Black wire is ground.  The Green wire is used for insulated rails at various points (where needed).  The outer rails are not tied together.
2. The Blue TMCC note is probably a bit misleading.  I do have the TMCC wire running to all the ground wires of all 8 power supplies on their way to their respective district tracks.  It's overkill, pure and simple.  One TMCC wire would do it.  But do note that all grounds are tied together, including the accessory transformers.  I'm sure what you've done is just fine.

You can follow the layout building thread "PRR Panhandle Division 2.0" on the Photo sub-forum.

George

Thank all of you for great info. How much current can CAT5 handle?

Clearly thins have changed since the old days of O22 switches!

CAT5 is typically #24 wire, and most CAT6 is #23 wire.  It's probably pretty marginal for O22 switches, but the modern switch machines like the DZ-2500 I use just sip power, so they aren't challenged by the small gauge wire.
