QuestionQUESTION: I recently added another 0 gauge train, running on it's own 0-27 track, to my Christmas scene.
I'm assuming by what you're saying that both wires of each lock on go directly to the power supply and not to each other. Yes, the wires go from the power supply to each Lock-on and not daisy chained to each Lock-on. There are several devices that can be used so a train, when it passes over or by a device, will activate the device, thereby activating the accessory attached to the device. The complete cost of this project including the camera ($73), searchlight car ($30), and parts ($10) was $113. Here is a modified circuit that supplies the camera with battery backup power when track voltage goes below 12 volts. The complete cost of this project including the camera ($73), crane tender car ($35), parts ($7) and battery pack and parts ($37) was $152. Update: Instead of making the cable yourself you can purchase a ready-made cable from MTH for approximately $20.
For our O Gauge Model Railroad Layout Project for a Spare Bedroom, we used a way to connect power to the track that is totally invisible from above – we soldered the power wires onto the bottom of the rail. We start out with two lead wires about 18 inches each: red for the center “hot” rail, and black for the outside “ground” rails.
Just as you must strip the insulation from the wires before inserting them into the Lionel CTC Lockon, you must strip them before soldering (Figure 3). While you can strip wire with an Xacto knife by lightly rolling it back and forth until it cuts through the plastic insulation, and then removing the piece of insulation by sticking your fingernail into the cut and pulling with your finger and thumb, I use a handy automatic wire stripper (Figure 4) that grabs the insulation, cuts it, and then pulls it off.
As shown in Figure 5, we used a “third hand” with an alligator clip at the end of it to hold the red “hot” wire in contact with the center rail while we heated the rail at the tip of the wire with a small soldering iron. Repeat the process with the black “ground” wire, attaching it with the bare wire running the same direction as the other lead, and close to the part of the track section where the other lead is attached, as shown in Figure 6. After the solder joints have cooled, it’s a good idea to check their electrical conductivity with a multi-meter. On the other end of the soldered leads, we will install spade connectors, as shown in Figure 8. Next we drilled a hole through the roadbed and subroadbed where the wires will be when the track is attached to it. The easiest way to connect these to the power wires coming from the transformer is to just drive two screws part of the way into the benchwork, place the spade connectors from the track leads and the transformer leads under the head of the screw, and lock them together by tightening the screws down on the spade connectors, as shown in Figure 11.
We will, instead, be using barrier block terminal strip connectors where we need to make connections throughout the O Gauge Model Railroad Layout Project for a Spare Bedroom.
The track power leads connect to one side of the terminal strip, and the transformer power leads (note we used the same color wire to visually confirm which wire needs to connect to which) to the other side of the terminal strip. When creating a miniature railroad, electricity is routed from a 110-volt AC source (220-volts overseas) plugged into a wall outlet, through a transformer that reduces the voltage, and then to the locomotives, rolling stock, signals, lights, sound systems, and other devices. Understanding the amount of electrical current drawn by various locomotive motors, lighted passenger cars, accessories, and lighted or animated scenery is important to ensuring the right size wires are selected. Wiring skills involve stringing and routing wires from one point to another, supporting them along the way, and joining them by soldering joints or crimping connectors.
Troubleshooting electrical problems can be a very time consuming effort since there may be many connection points between your transformer and track or accessories. If you decide to rewire your layout, I suggest that you adopt your own standards based on certain rules of thumb. I have found that the best cure for one's apprehension about tackling a wiring job is to draw a picture of the wiring.
The 'art' of soldering correctly is a skill learned over time since your first attempts to ensure a mechanically and electrically sound splice or connection will be by trial and error.
Last, the right tools will make a very big difference in how well you test layout electrical circuits and CEMs, trouble shoot problems, strip insulation from wires, attach solderless terminals, and solder.
Two other wire features are also important: type of insulation (plastic, paper, cloth), and whether the wire has a stranded or solid metallic conductor.
Modern wiring for toy or model train layouts most often has a thin plastic insulation over the conductors. Short circuits occur whenever two un-insulated or bare electrical conductors touch each other.
On your train layout, short circuits are not usually so dramatic since the voltages are low.
If the short circuit current draw is not sufficient to cause local area heating, then low voltage shorts are often difficult to find especially if you have a lot of wiring. For example, suppose that you use #20 stranded wire for connecting to turnout motors and solenoids. This is one instance where you may wish to either 'tin' the end of the stranded wire or crimp a solderless terminal onto it after striping its insulation and twisting the strands together.
A major problem with short circuits in recent times has been the loss of on-board electronic command control and sound systems due to a derailed train.
An open circuit is one in which there is a discontinuity along a wiring path over which electricity does not flow. When working with AC, it usually does not matter whether you connect one or the other power wire to an accessory even though it is normal to connect a transformer common to a side rail and lettered post to the center rail. Whenever you solder wires, remove only enough insulation with your wire stripper to allow the clean, bare conductors to be twisted together so they have mechanical strength, and then solder them together. Segmented Wiring: I run a 16-18 gauge 2-wire conductor from two transformer terminals to a block. By organizing electricity distribution by segment, maintenance, trouble-shooting, and changes are much easier to accomplish.
Since no devices are attached directly to the transformer posts, reliability is enhanced because you have eight screw terminals from which to draw power, not just one.
The left terminal block is a distributed DC power point, and various accessories like a highway flasher, station stopper module, & others use the right terminal block. Wires above the terminal blocks lead to the power sources and central control panel, and wires below come from the individual soundboards located in the engine house, sawmill, and others. Use either spade or loop connectors for reliable wiring and for connecting a wire to a terminal block. Rely on your diagram when stringing and connecting your wires, and follow your diagrams and the previous guidelines for cutting, stripping, crimping or soldering wires in order to ensure neat and reliable layout wiring. Trouble-free train operations will more than justify the extra time that you spent ensuring that your wiring is as reliable as you can make it. If any problems do occur with a properly wired layout, it will be much easier to find them.


Amos Realistic Then tie the wires from each cab a tell apart powerpack Beaver State comptroller to on each then the trains rivulet and switch the DPDT switches of the occlusion ahead of the locomotive.
It is a very large rectangular layout about 6 ft by 8 ft, with the train running on the outer edge.
So you should have 4 wires total coming from the throttle, 2 wires together from each side of the throttle control portion of the power pack as shown in the diagram below.
Spring loaded devices sit beneath the track and are activated when the train passes over them.
The control rail is an outside rail that does not have power from the transformer attached to it.

These handy devices clip onto O Gauge tubular model railroad track (Figure 2) to bring the power from your transformer to your trains. Even if you’ve never soldered before, this technique is easy, eliminates the need for Lionel CTC Lockons, and reduces the chances a wire will come loose from the rail and break electrical contact. You can use any color you like, just be consistent so you don’t have to remember later which wire is soldered to which rail, as you would have to remove the track from the roadbed to find out. This tool makes short work of the many connections we will need to make in wiring our O Gauge Model Railroad Layout Project for a Spare Bedroom. A soldering iron is another inexpensive tool that will come in very handy not only on this project, but many others around the house.
Better to find a bad solder joint now than after the track has been screwed down to the roadbed! While soldering gives you the sturdiest joint, we will be making our next connections under the benchwork, working over our heads, a situation in which using a soldering iron is just asking for a hot drop of liquid solder to drop on you. Because we are working with low voltage, you can get away with this type of connection, however, we DO NOT recommend this method, as it would be easy for a stray wire to short circuit this setup.
As shown in Figure 12, these handy little devices have a plastic base with plastic walls between the connections to keep them from short circuiting. A metal bus connects the left and right connector screws so you get good current through your connections. Electrical current demands determine the size of the wires needed to distribute electricity needed for flawless operations. With simple skills and some common sense, you should be able to ensure your success and safety. One hundred percent reliability means there are never any failures in the electrical distribution system. Each connection or wire segment must be isolated and determined to be trouble-free, before moving on to successive points in your distribution wiring.
However, if the layout is operating but there are frequent or intermittent electrical problems, then start over to rewire your layout in order to ensure future reliability before expanding it.
What everyone should know is that model locomotives generally require more 'power' than do caboose lights. This is usually called a 'wiring diagram.' I've been wiring train layouts for over 50 years, and always draw a diagram, no matter how simple the job. This is sufficient for low voltage applications, but if a wire's insulation is broken, a short circuit may occur.
You may have experienced a short circuit in your home when frayed insulation allowed two lamp cords to touch causing a spark and a loud popping noise and perhaps blowing a fuse or tripping a circuit breaker.
Segmented wiring makes it easier to isolate problems as does adhering to your standard wiring practices and carefully following good installation procedures. If you strip the wire and wrap it around a screw-down type terminal, it's possible that one of the tiny wire strands may be dislocated and inadvertently pushed aside it could contact an adjacent wire. Tinning the wire means soldering the very tip with just enough solder to keep the strands in permanent contact, but not so much solder that the wire looses its flexibility. The newest electronics are very sensitive to rapid current increases resulting from a short circuit.
However, some electronic modules used as detectors or timers may require that you adhere to certain connection standards or the device will not work. If you have wired a circuit, but the device doesn't operate, you can test for voltage from the transformer outward.
A 75-watt iron or gun will ensure that you have enough capacity to sufficiently heat larger gauge wires so that the solder flows through the joint to ensure a solid electrical connection.
When the joint cools, cover the soldered joint with either electrical tape or shrink tubing. Large O-gauge layouts with scale sized engines pulling long trains on several hundred feet of mainline track, 12-gauge wire or heavier may be needed to not only handle the heavy power demands but also reduce the voltage loss due to the wire's internal resistance. This helps to ensure that all power connectors are screwed down tight, make good electrical connection, and look much better. Just looping a bare wire around a terminal block screw and tightening it will eventually cause problems with poor contact between the wire and the screw, and corrosion that causes high resistance.
It's available in electronics stores in both long and short lengths and various diameters to accommodate all wiring gauges.
If used to insulate small gauge wiring joints, the tape's inherent stiffness causes it to unwind from the joint that could bare a conductor causing a potential problem. Cut it to whatever length you need, peel off the backing from the loop tape and stick it to the underside of the layout. Loop Wiring If you use a DPDT center off tack the block can also represent off completely so neither taxicab has control ampere really useful feature model railroad cab control block wiring. This method will not work with standard tubular track that have metal rail ties*, but works well with track that have plastic or wood ties.
When the train leaves the isolated rail section the signal turns yellow, and then after a short time, returns to green . They provide a sturdy connection with good electrical contact, but they stick out like a sore thumb, especially if you plan on ballasting the track with gravel. A simple matter of loosening a couple screws, unless you have already ballasted the track, in which case, much prying and cursing will be involved. Once the rail and wire get hot, touch a thin rosin-core solder wire to the rail and the end of the bared wire away from the soldering iron. Only one black “ground” wire needs to be attached, as the metal ties of the track create an electrical connection between the two outer rails. Set the meter to read electrical resistance (measured in Ohms), touch one meter lead to the far end of the wire you just soldered on, and the other down the track section a bit on the rail to which that wire is soldered, as shown in Figure 7.
Also, a soldered joint is a permanent joint, so any changes to the wiring later would require wire cutters. If you feed them through the hole one at a time you can get away with using a slightly smaller hole than you would need to cram them both through at one time.
We will be using a lot of these devices for connections around the benchwork of our O Gauge Model Railroad Layout Project for a Spare Bedroom.


This article guides you through the selection of proper wire sizes and connections to enable smooth flow and distribution of electricity to all parts of your layout, and to avoid problems caused by short and open circuits. Although most of us will always find some glitch in our wiring no matter how well planned and executed, we still should be able to attain reliability in the 90% plus range.
Thus, sticking to a standard way to connect and solder wires and segment electrical distribution with terminal blocks will surely lead to easier troubleshooting in those times when something does go wrong.
The latter consideration is very important if you intend to use either Lionel's TMCC™ or MTH® DCS™. Intuitively, a six-motored A-B-A diesel lash up needs more electrical current and higher voltage (the combination of 'current' and 'voltage' is 'power' in electrical terminology) to run at scale speeds than does a single motor yard switcher.
I always check supplier's wiring diagrams for accuracy, and if it is not clear, I'll call the supplier's technical support desk for clarification.
This is not because I can't solder, but because I've found it to be faster and better to use spade and loop terminals for connections to terminal blocks and butt connectors for splices. The current rise due to a short may cause a wire to heat up enough to burn you even though the voltage is low.
Therefore, a fast acting circuit breaker between your transformer and the track are mandatory especially if the transformer is not one of the newer models designed to work with command control systems. Place the meter probes on each connection point and watch for volts on either the swinging needle (analog meter) or digits (digital meter).
This makes many wiring jobs go faster especially if you are opening and tightening many terminal blocks' screws. All my main power leads from multiple transformers are connected to terminal blocks under the layout. At an 8-position block, I connect one of the transformer leads then link each of the positions with a jumper wire so that now I have eight points to which I can connect some track or device.
If more than eight connection points are required for either lead, jump from the first terminal block to a second one where there may be two, four, six, or eight additional screw posts. Further, if using stranded wire, a loose strand may accidentally touch a neighboring terminal thereby causing a short circuit. Slip a length of tubing over a soldered joint and heat the tubing with a lighted match or heat gun to shrink it over the joint. If a joint is subject to abrasion, however, a tape or a crimped connection may be a better insulator since it is possible to inadvertently scrap off the coating thus exposing the conductor. Leave the backing attached to the other strip, trap the wires between the two Velcro pieces, and press together for a very satisfactory wire management solution. The whole idea is to spend your time running your trains, not constantly lying on your back under your layout tracing wiring problems. The selected taxicab will and so control whatsoever train that is atomic number 49 that tail block. These devices do not work well on a permanent layout and with engines and rolling stock of different weight. The best way to isolate a section of rail is to use plastic rail joiners or cut through the rail.
They also can come loose if something hits them, or if, over time, they just lose their springiness they can slip off the track, or the wires slip loose from the terminals. We are using heavier wire for our leads than that supplied with the lockon, which looks to be about 22 gauge. This makes sure the heat of the wire and rail, not the soldering iron, is what causes the solder to melt, ensuring a good solder joint.
Small fiber or plastic shims between the metal tie and the center rail keep it electrically isolated from the outer rails.
In keeping with our modular benchwork design, the spade connectors will allow us to disassemble or change wiring later without difficulty of cutting and resoldering. What you end up with after the track is attached to the roadbed is dangling power leads under the benchwork as shown in Figure 10. Consequently, the wires needed to supply the higher power requirements of mainline diesels or steamers need to be larger than for yard operations. Nevertheless, you will need to solder from time to time, so it pays to work on your skills. If your trains are not running smoothly, you can test the track voltage at different points to determine if voltage is lost either due to track or connection resistance. The other transformer lead is then connected to a second block with jumpers to give me eight appearances of that lead. Track Wires To see them and memorizing the electrical blocks requisite for multiple cab control.
When a train passes into the isolated track section power is applied to that section, from the powered outside rail, by the metal wheels and axles. If the solder is melted by the soldering iron before the rail and wire are hot enough, you may get a “cold” solder joint that doesn’t conduct electricity well, and is subject to breaking loose. In the photo, the black meter lead had not quite touched the center rail when the camera shutter fired, but when it did, the needle shot to the right side of the meter, indicating there was no impedance in the connection.
To attach the spade connectors to the ends of our leads, we use a crimping tool as shown in figure 9. This is especially true if your layout features many grades where the locos exert more pull and thus demand more electricity in order to keep the train's speed constant.
Colored coded wires, solderless connectors, and segmented wiring make it much easier to ensure that polarity is followed and to trace a wire back to its source. Be sure to use a 'heatsink' when soldering wires to electronic components to prevent overheating.
When the solder begins to melt, the rosin-core flux will cause the melted solder to be drawn into the joint. This tool works much better than pliers, as it has teeth than pinch into the metal of the spade connector rather than just crushing it, making for a very secure joint.
A common heatsink is a small, spring-loaded, aluminum clamp that is clipped onto a component's lead to absorb soldering heat. S One disfavor with taxi control is as you need more trains the Cab selection switch wiring becomes more. Once the joint is filled with solder, remove the solder wire and soldering iron and let it cool.
DC block control remains a practicable agency of powering a layout yet and if through The wiring shown here is for ii cab surgical process for clarity but away substituting Model railroad track overturn.
