Layout wiring help and advice

Use 14 or 16 gauge stranded copper wire to make your connections. If you can get paired wire that differentiates (usually color or striping) between pos and negative, it will be easier. Strip each end of the first paired wire which has been cut to length for your first connection from the distribution board to the track. Crimp a spade connector to each wire end and connect them to the #1 posts of your distribution board using a Phillips screwdriver, and note which colored or striped wire is connected to the pos and neg posts on your distribution board.

Run the wire to the first place you want to connect to the track. Since you are using Fastrack, purchase these .110 female connectors off Amazon. Strip the wire ends of your paired wire that will connect to the track and crimp one of the female .110 connectors to each wire end. Now flip a piece of standard Fastrack over (not a switch or fitter piece) and there should be two metal tabs in the middle - one for pos to the center rail and one for common to the outside rails. Slide the respective female connectors over the tabs being sure to observe correct polarity and you're done. Now repeat the same procedure for 11 more connections from the distribution board to your loops (6 connections each loop), spacing the connections out on the trackage as equally as you can.

Now connect your transformer to the input terminals of the distribution board, again observing correct polarity.

For a neater look, you can drill holes in your layout table top under each piece of track you intend to use for a connection and run the wires from the distribution board up through the table top and then to each track connection.

Hope this helps.

I think I’ll stick with the black and red, just to keep thing simple, red for positive or hot and black for common. Keeps things simple. Another question, can the transformer connections be 14 or 16 gauge wire? They say that electricity flows like waters, the bigger the tube or pipe, the more water flows through. Kind of the same thing for electricity and wires.

Hello, I have been dealing with a voltage drop issue for a few months now and I finally got some time to work on it. My layout consists of two loops of fastrack. The bigger loop has O-48 curves and the smaller loop has O-36. The loops are connected with command switches both left and right hand. (These are also in O-36) My layout is powered by a single connection to the track via a CW-80 transformer. I also have the original command base to run command equipped locomotives. I have been doing research on this issue I’ve been having on the forums and in articles.I tried tightening pins, that didn’t work. Soldering jumpers had a temporary fix but didn’t last overtime. So I finally got a MTH 12 port distribution board and need help with connections. My question is, can I run bigger wires on the distribution board to supply more power? How would I make the connections? Sorry for the long paragraph, this is my very first layout. Although I’ve been running trains on the floor for years, this is new to me.

What you are really asking is about is resistance. The amount of amount of voltage drop over a given wire versus distance and load. Here is a simple way to find out:https://www.omnicalculator.com/physics/voltage-drop.

I’ll use this after the wiring, but my layout 100 percent needs to be wired. If the fastrack doesn’t work after that, I’ll have to switch brands unfortunately. But let’s hope I don’t have to do that.

Also for the main feeder I use 14g speaker wire. Two colors copper and can be purchased on Amazon at a good price.

My personal preference is 14 gauge from transformer to distribution board and 16 gauge from distribution board to the underside of the Fastrack.

Attached is a picture of how the connections to the underside of the Fastrack pieces should look.

Good advice to date. Apparently you are wiring your layout with Lionel technology.  So the paths of the power wires that connect to the FastTack pieces doesn't matter much; just install wires along the shortest distance(s).

You may know that MTH recommends using a "star" wiring pattern with all wiring of feeder paths cut to the same length. In your case, you can ignore that point.

Carry on ...

Although I’m using Lionel Technology, can I still use the star wiring method? I’ve seen a video on that about a week ago. It looks a lot simpler than the bus. Plus it’s fastrack so I pretty much don’t have to solder due to the connectors you can use.

Sounds like a lot of wires, how much wire would I have to buy in order to complete this? Maybe 100 feet or more, I’m not sure. I’ll try to keep you guys updated as I begin this process.

You don't need a bus line - the MTH distribution box ("d-box") replaces a bus line. Just connect your CW-80 transformer outputs to the red and black terminals of the d-box and then connect the 12 terminals of the d-box to your two loops about equally spaced apart as explained above.

One way to get close to a star pattern is to mount your d-box to the underside of your table top in the middle of the layout and run your transformer outputs to it. Then just run the d-box terminal posts equally around the layout from underneath.

Attached are two pics showing the transformer connection to the d-box and then the output wires from the d-box to the track. Also, a layout diagram with only 5 connections for illustrative purposes, but you'll need at least 8 (four for each loop).

I can't explain it much better than this. It has nothing to do with whether you're using Fastrack or any other type of track system.

Without knowing the size of your layout it's impossible to know how much wire you'll need. At a minimum, you'll need 8 lengths of red wire and 8 lengths of black wire to run from the central d-box location to each of the 8 track connections. How long each wire length needs to be will simply be a reflection of how long the run is from each d-box terminal to where you connect to the track. That's why I earlier suggested using paired wire, since you only need to make one run (and split the wire) for each track connection. You'll also need wire to connect the transformer to the d-box.   

You can see in the marked photo with the yellow circle how using paired wire makes the wiring job much easier.

I found some paired wires on Amazon but I think they were made for cars, could this work for my layout as well? Also, Richie C. Why type of connectors do you have that are connected to the terminal post on the D-board?

It's been strongly recommended here on the Forum to avoid that type of wire.  It's copper clad aluminum.  Maybe you don't intend to solder it now, but it you ever do, it's a poor choice.  I suggest spending a little more on pure copper stranded wire, like speaker wire.

I found another example of wires, this time it’s copper but it’s tinned, I also have a description on the wires themselves. Sorry if I am bringing up different types of wires, I’m just making sure I buy the right thing.

Silicone insulation is very flexible, but PVC is fine for track feeder wires. IMO, high strand count wire doesn't hold crimped connectors as well as something like this:

Have you had success with these and crimped connectors? Just thought I would ask before buying them. I was busy again so I couldn’t do anything with the layout for a little bit.

Yes, I've had success with low strand count wire and crimped connectors.  A few things help improve the long term reliability rate:

1. Follow the crimp connector manufacture's guidelines for selecting the correct size connector for the wire gauge to be used.  Industry standard is blue for 16 gauge wire.
2. Good crimpers really help.
3. When stripping the insulation, I like to barely separate the cut piece of insulation and temporarily leave it on the end of the wire.  Next I twist off that piece of insulation, kinda like removing a screw.  This twist gives more for the crimp to grab and keeps salt and oil from my fingers off the copper.

If you want the ultimate low resistance reliable connection, tin the wire ends and solder on the connectors.

OR.....you could do what I do!

Hey guys I plan on buying the disconnects today, I found a brand called no main, I  used there 18 gauge female connectors and they just didnt make a tight connection. So I found another brand for the 16 gauge connectors, has anyone tried this brand? They cost $3 plus tax.

I meant to say Baomain.

FROM THE MODERATORS:
When you make a mistake like this, just edit your original post and fix it. There is no need to  make another post like this.

Adding the extra terminal feeds should resolve the issue.  Im still perplexed why the soldered jumpers don’t work.  Here’s a pic of what I did, just because for me it was simpler on a large permanent layout to solder rather than add terminal connections every piece of track.

Reliable trains are more fun!  Glad you are persisting!

I’m shocked I didn’t work for me either, but at least I can learn some new skills along the way. I’m not sure if it’s because they were 18 gauge. I had no issue with the 16 gauge at the r that one was soldered, but I think this method will distribute the power better. I’m also trying everything I can because it’s not the engines themselves. Both of my command engines started  acted erratically ever since I had this issue. Maybe I just got a bad set off Amazon? Hopefully when this is all finished, I can run my trains like I intended.

one question, since I’m wiring my layout, does that mean I can get rid off the jumper wires soldered jumpers under the track?

It’s been awhile, but I managed to get the connectors and the wire for the track connections under the layout. Should I get the same brand of wires for the 14 gauge? Another question, what size connectors are needed for 14 gauge spade connectors that hook up to the transformer. My last question for right now is what type of connectors are needed for the distribution board itself. Should I get some type of spas connector or is there something better?

If you only need short lengths of the 14 gauge wire for your bus wiring (between transformer and distribution block(s)), buying THHN stranded electrical wire cut to your desired length by the foot at a home improvement store may be less expensive than buying a longer than you may need roll of 14 Ga pure copper speaker wire (plus shipping).  14 Ga. THHN stranded is usually available at most big box home stores with Black, Red, Blue, White, and Green insulation.  Check the short unwanted cut wire section for discounts.

For crimp connectors, fork terminal connectors with a blue jacket are meant for 14 to 16 gauge wire.  Note that the fork's inside dimension needs to be wide enough to go around the terminal screw, and the fork's outside width dimension needs to be narrow enough to fit inside the terminal block separators (plastic nub between adjacent terminals).   These connectors are also available in the electrical section at home stores.

Hello everyone, sorry if I was too busy. Recently, I got the THHN stranded wire in 14 gauge. The only thing I need now to begin wiring everything up is the terminals. The terminals that fit the distribution board were the size 2-5s. Does anyone know where I can get more of that size in a store somewhere or is Amazon my best bet?

You should be able to pick up similar forked terminals at your local box store like Lowes or Home Depot. Make sure they are sized correctly for the wire you are using and that the "forks" are wide enough to fit over the screws on the distribution board but small enough to fit in the distribution board terminal slots. You may have to experiment to find the perfect fit.

Even if they aren't a perfect fit, you can make the "forks" slightly smaller or larger, as required, using a pair of pliers.
