Power to run our model locomotives has to be put on the rails or track from the Command Station or Booster.
Others have gone into great detail and technical explanations as to why the bus wires should be a certain size, so I am not going to repeat them here.
Because our Bus wires are usually AWG 12, in most cases they will not fit into the track connections on most Boosters.
The purpose of a power district is to increase the power on the layout tracks of a large layout.
A Power District is an independent section of layout bus wiring which is connected to or powered by a Command Station or Booster.
My rule of thumb for the length of AWG 12 bus wires for a single Power District is 25 to 30 feet from the Booster in one direction. Power Districts that are made by using Circuit Breakers are called Sub-Power Districts because they are powered by the same main or auxiliary Booster. In the example of the Power District in the above section that had three legs, each 25 to 30 feet long, it would be better if it were to be divided into three Sub-Power Districts, each with it’s own circuit breaker or other current limiting device in case of a short on the track.
Most DCC manufacturers make some form of Circuit Breaker module or board for their systems. The Circuit Breaker typically has it’s input connected directly to the output of a Power Booster. Circuit Breaker boards or modules also vary in the number of output legs they have, or the number of sub-districts they can be connected to. The way it works is as follows: If there is no short and no locomotives on the track, the bulb will not have any current through it. The number of feeders used and their wire size is a debate in the DCC community that is always being discussed, debated, and argued.
From the information above, you can see that Track Feeders can be a system all it’s own.
Now let me tell you that I am an Electronics Technician and have been working in the field for more than 40 years, and a model railroader for most of those years. So as you can see, there several ways to attach and run feeders, and most will give you good performance.
Discussion related to everything about model railroading, from layout design and planning, to reviews of related model tools and equipment.
I'm new here and just entered this hobby for a few months, so please forgive me if any question I asked is too simple.
I really would like to add one DCC sound decoder into it but after I deseperate the locomotive, I found there's NO main control board inside to accept the decoder. It seems that this boarder has an 8-pin decoder plug in, so could it be used as the main control board for the SL? Anyway, I'll try to put both decoder and speaker inside the boiler firstly to see if the loco runs ideally. If not, I'll move the speaker to the tender and you can see the tender has already got hole-opened floors there.
Very nice steamer, and it looks very much like you have succeeded with your decoder and speaker installations.  Congratulations!! The DCC protocol is defined away the Digital Command ascendence Working radical of the National Model Railroad tie-up NMRA.
That doesn’t mean telephone wire, which is 24 gauge, or AWG 24 (American Wire Gauge). Again the rule of thumb is, if the wire will be flexed, bent, or under vibration, use stranded wire. If this is the case with the system you have, you will need to connect a pair of smaller shorter wires between the main Bus and the Booster. One Command Station Booster is usually not enough to power a large layout as found in a two-car garage or larger.
As an independently powered section, if a short occurs in one power district, only that section of layout is affected.
If the Booster is in the center of the bus, the bus can go in two or three directions, each 25 to 30 feet long, at the same time. As an example, one sub-district could be a classification yard, another could be the engine facilities, and another could be the main-line.


The placement of the circuit breakers would be best if they were right at the output of the Booster, thus each Power Bus leg would have it’s own circuit breaker or current limiting device. One type is strictly a fast acting Electronic Circuit Breaker that disconnects only one power leg or wire when a short occurs. When a locomotive or two is on the track, a small amount of current (and DCC signal) will flow through the bulb. Most rail joiners will pass current when we first install them, but once we add scenery and ballast, and holding it down with water and glue, they have a tendency to not work as well. One thing to remember: Wires in parallel will reduce the resistance and increase the current carrying capability.
LGB (European prototype)and Bachmann (USA prototype)are narrow gauge following European practice at 1:32 life size.
If you are dead set on using an 8 pin plug then I would look into scrounging an older Life Like plug with solder pads that they put in their GP7 and GP9 locos or any good DCC shop would have a smaller plug you could use. I will leave it to one of the more advanced people here to help if the motor does need to be insulated.
The older open frame motors usually has one brush holder non insulated and the motor frame is attached to the frame.

If the current protection device, usually an electronic circuit breaker built into the unit, does not trip and turn off the track power, the wiring is not sufficient in conductor size.
This bus is actually the main trunk line and is of heavier wire that runs under the layout and starts at the Command Station Booster and usually follows the track around the layout. When you add parallel wires, you effectively increase the current capacity and reduce the resistance.
The limiting factor in having this much wire in one Power District is the number of locomotives that will be present and running on the track in the Power District at any one time, and the current capacity of the Booster.
Or the layout could be divided down the center with one Sub-Power District on one side and the other Sub-Power District on the other side. Another type is an Electronic Circuit Breaker that disconnects both power legs or wires when the output is shorted. Some Circuit Breaker boards are also designed to provide some form of feedback to the operator. As stated before, the object of any current protection device is to remove or limit the current supplied to the source. Since the current is low, the filament will not heat up and glow, thus the resistance of the filament will also be low, allowing current to flow. On the other side of it, our track is a structure in our layouts, and it expands and contracts with temperature, so some gaps must be left or the track will buckle.
This type of gap is not the same as an electrical gap that is insulated, although insulated electrical gaps can be used for expansion purposes. So if you wire things differently and your locomotives seem to slow down, add more feeders.

It’s not group A surprise thus that DCC has get the fresh standard method of controlling axerophthol model railroad layout.
The test then, is to place a quarter on the track at various places around the layout and see if the circuit breaker trips and shuts down the track power. If you have a small layout that has a circle of track, do not connect the bus together at the ends to make a loop. A layout that fills a two-car garage can also use AWG 12, but should be broken up into separate Power Districts, each with their own Booster. And, the larger the layout, the more locomotives we put on it, thus the more current needed. Considering that each HO locomotive with sound will draw about 700 ma each when running, 7 locomotives with sound could be running in a Power District that uses a 5 amp Booster.
And yet a third type is a Circuit Breaker that disconnects power by closing or opening a relay. The 1156 lamp would be wired in series in one leg or wire coming from the Booster and connected to one power district leg. If a short occurs, the full current from the command station or booster will flow through the bulb. If you don’t solder your rail joiners, in order to insure a stable electrical connection you should probably do one of two things.


I have some sort of gap every six feet, either and expansion gap or an electrical gap for a block.

However, because the DCC system is capable of providing more current to the track than our old DC system, the size of the wires used in various places is different.
When you run the second set of wires, you do need to connect them to the old wires (observing the polarity or phase so they will not be shorted) at about every three to six feet. These wires should be six inches or less in length, and should be soldered to the Bus wires, or connected to the Bus through a terminal block. So the amount of wire, or length of the Power Bus, is also dependant of the number of locomotives which will be running in the Power District at any one time. Power Districts that are made by using Circuit Breakers are called Sub-Districts because they are powered by the same Booster. The short will not cause the whole layout to stop working, just the section with the short in it. Some even will provide a line, connection, or plug to provide status information to a remote location or even a computer interface. This trade off starts with where your model railroad is located, and what kind of temperature changes it will go through during a year.
Solder a feeder on every piece of rail, or, solder an AWG 22 jumper wire from one rail section to the other around the rail joiner. Each manufacturer provides hook and loops for their equipment, while at the same time touting their style of knuckle coupler. If a short occurs on the layout, the small wire size will not allow enough current to flow from the Booster to the short, and the circuit breaker will not trip and will not stop the current flow.
In most cases, you can use an Electronic Circuit Breaker made by one manufacturer, on another manufacturers DCC system. When that happens, the resistance of the filament increases because all of the power is being used to light the bulb. If you want to run your track feeders two feet before they are soldered to the power bus, use AWG 20.
To add to the mix, Kadee is also a player in the coupler field, with two or three different (or more) sizes of knuckles, depending on the scale you are working in. A large number of these locomotives are still in service today either with the original purchaser or with a second-hand operator. If the current flow does not stop, it is possible to melt or damage some parts of whatever is causing the short or, if left on a long time, burn the insulation off of the wires, which in turn may cause a fire. The gaps both in the track and bus wiring should be at the farthest distance away from the Booster. You can get away with AWG 20 if you are using code 83 or larger rail and use the solder sparingly. They get soldered to the rail, go down to the bottom of the sub-roadbed, and are formed into a small loop.
As to compatibility of couplers and other variables ask your hobby dealer to show you different items and explain any compatiblity issues. The CN units were built originally for the Burlington Northern and were later purchased by the Illinois Central before transferring over to Canadian National.
For that reason, it is important that the wiring be of the right size (or larger) and be done correctly.
The reason we do this is, if the bus and track were in a loop, the DCC signal could be corrupted because the signal coming from both directions at the same time could cancel parts of the signal out, and control of our locomotives may become intermittent.
They are used with other CN power on all types of freight service and are occasionally used in pool service with other roads. We do want to hide our feeders if at all possible, because if you see wires connected to the track, it will ruin the illusion that our railroad is real.
Then I solder an AWG 18 insulated wire from the loop formed in the AWG 22 feeder to the Power Bus.
If the track section is part of a block that will be detected electronically, the wire used from the feeder is AWG 16 and runs no longer than 14 feet to the detection board. In the photos and videos that we take, we want the viewer to think it is a real railroad and not a model.
