However their are times when solid wire has advantages, particularly when soldering in small locations. Setting up train signals for your layout is another fascinating aspect of using electronics and special wiring effects in model railroading. Setting up a simple system of operating train signalsFirst you have to decide whether you want to use track circuit detection or position sensor detection. Model Railroader managing editor David Popp shows how to use insulation displacement (suitcase) connectors to wire underneath your layout.

I'd like to wire up some switch status indicators, and I've been searching, but every circuit out there either requires two separate switches or runs on DC power.
Since most of the nifty logic-controlled momentary-switch activated indicator circuits run off 12V DC, can Atlas switches run off 12V DC power or will this fry them? If anybody's got a way to run two lights off of the 16V AC momentary setup, I'd love to hear how it's wired. Atlas switch machines will run off AC or DC since all they are is a coil of wire at each end of the plunger to attract it by magnetism when the coil is powered. I have always used Atlas & Peco switch machines wired through a capacitor discharge circuit which gives a good jolt of AC to the coils and don't run contacts for signals or other auxiliaries off them. Post a link to the indicator circuit you are thinking of using so we can see if there is a way to interface the circuit to an AC powered Atlas switch solenoid.
Just wire it in parallel with the switch machine you now have and it will basically give you a DPDT switch that you could connect lights to using whatever power source you want. I like Mark's idea of using the Atlas snap relay, but I assume I could just buy a few components from Radio Shack (cheaper) - if only I knew what I was doing.
Due to the coil being only momentarily energized a latching circuit is required to 'remember' which direction the turn-out coil was energized in. I plan on tackling this in stages, since I'm feeling pretty stupid right now and don't want to keep frying stuff. Yes, you have the correct circuit isolated to get you DC power (second schematic in above post. The last schematic should work (I've never tried it) and also sounds like the circuit Mike uses (see post #2).
When the switch is thrown, S1a down & S1b up, the energy stored in C1 discharges into coil A.


Expect to goof up and cause some thing to smoke, then figure out why it smoked so you don't do it again. Lighted billboards are another great way to add lighting effects for realism and excitement to your night scenes. A great way to add realism to a fire scene or accident scene on your layout is to add police, rescue and fire emergency vehicles with flashing beacons that grab your attention. Some DCC systems also recommend solid wire for certain applications.The insulation on the outside of the wire also varies greatly. A flip-flop will hold its two outputs (pins 3 & 4) at the level momentary presented to an input (pins 1 or 6).
Since you have 16VAC a 'full wave bridge' rectifier and a filter cap is all that is needed to power the circuit you posted. Once it is charged C1 (+) is at the same voltage as the input voltage and no current is flowing through R1. The cap has stored a fairly high amount of energy which will energize coil A causing the turn-out to switch. Some of the variables are obvious, others not so much.Different wiring projects call for different standards. In most cases, because we are dealing with relatively low voltage and amperage and in normally stable temperature and humidity climates, our wiring does not require any extra insulation. In essences the flip-flop 'latches' a momentary high voltage level (digital logic levels) so the corresponding LED stay lit after the SW is released. The CD4011 is rated for up to 15VDC so you will need to measure the output voltage from the rectifier to ensure it does not exceed the CD4011's max rating. If you're experiencing problems with your wiring due to humidity for example, you are going to face even greater issues with the trains and tracks themselves. Note that when working with specific products, manufacturers will often recommend a wire size and type. In the mean time, being the the switch is now in the other position, C2 charges through R2 to get ready to engerize coil B when the switch (S1) gets thrown again. Heavier insulation not only adds to the cost of the wire but also makes it harder to bend.Multi-conductor wire is also available.
Multi-conductor wires with many strands of finer wire are more common for telecommunications and electronics.
These can all have uses on your layout.Although it will not have any impact on the performance of the wire within, choosing multiple colors of wire, and standardizing on a specific color for each function, will go a long way in making your wiring easier to install and easier to detect flaws later on. But a 12 gauge solid wire is one strand, while a 12 gauge stranded wire may be made up of more than a dozen much smaller individual strands spun together.In most cases, stranded wire is preferred because the multiple threads provide more conductivity and flexibility.


Although not necessarily a mandated standard, white, black and or red are used for track power on most layouts - if for no other reason than these colors are easiest to find.Track Bus and FeedersAs your layout grows beyond the basic oval of track that comes with most starter sets, a good power distribution network is essential to getting consistent performance from your train all the way around. Smaller layouts (a typical 4 foot by 8 foot being a good example) can usually get by with No. 16 since the length of the run from the power supply to the track is never more than a few feet.While it is tempting to just go with the biggest wire possible to guarantee excess capacity, there are drawbacks to putting in more than you need. In addition to the wire itself, connectors like crimp-on terminals and terminal blocks must also be purchased in larger (and more expensive) sizes. More on position sensorsa€¦Optical position sensors (photocells) are small devices made by Circuitron and Logic Rail that you can place between the track ties. At least one person I know created an entire Z scale model railroad empire inside a suitcase and displayed it at various train shows! Lionel uses red and black (red always for the center rail, black for the two outer rails) as a standard in its instructions and most 3-Rail O Gauge layouts are probably wired this way.If you are wiring with a common rail for your blocks, then keeping the common rail the same color all the time while changing the color for the other rail in each block is also an option. Whatever colors and pattern you choose, just make sure to keep a good notebook handy to reference later.Lighting and AccessoriesAdding lights to buildings, streets, and other scenic accessories usually does not require anywhere near the amperage demand of the trains themselves. Number 26 to 20 wire (depending on the length of your bus) will be sufficient for most applications.
There are other model railroad scales that have been used, but these are probably the best ones to use for the purposes and scope of this site.
And again regardless of scale or manufacturer, switch machines of these two types will have similar needs and performance.Twin coil machines have a higher current draw when in motion, but are also much faster-acting than the motorized versions. In either case however, voltage and amperage draw are low and peak for only brief periods.Because of this, like with lighting and accessories, your power supply and wiring for switch machines do not need to be as robust. The Logic Rail Signal Animator circuit boards are set up so that when a train covers a sensor, the signal turns red to prevent other traffic from entering.
Again, an independent power supply and distribution bus is a good idea for your switches.No.
With multiple switches, lights, power supplies and more all concentrated in a small space, color coding and neatness definitely pay off.The preferred choice for wiring control panels is telephone or telecommunications wire. This looks pretty realistic and fairly impressive to have train signals changing in synchrony as your train travels around the layout, even more so if crossing gates are operated automatically and if other lights or sounds or animated devices go on and off as your train passes.This is cool stuff!! Because the runs are short and power demands so low, this fine wire poses no safety threat.The same is true for other electronic projects around your layout and inside buildings, train cars and even locomotives.
