Not All Digital Decoders don’t implement all the CVs, but if the function is provided the relevant CV information must be adhered to. Described in a nutshell, Digital Command Control works by combining the output of a power supply with digital instructions telling the locomotives and other accessories what to do, directly onto the tracks. It is sent to a booster (or multiple boosters) where the DCC Commands are modulated onto the track power. The microprocessor the decoder is built around examines the data, and if it is addressed to it, acts on the instructions contained in the waveform. The decoder also rectifies the DCC signal into Direct Current to power the decoder, and applies power to the motor(s), under control of the microprocessor which is responding to the information encoded in the waveform.
Although Wireless DCC controllers have an RF transmitter in the hand (throttle), and an RF receiver that controls the DCC controller (command station).
The NMRA DCC standard covers the format of the information sent via Digital Command Stations to Digital Decoders. A packet is a bundle of data sent over the wires or rails in the case of model railroading.
The packet always begins with a preamble, in this case twelve bits representing a value of one are transmitted.
The DCC data packet consists of a preamble, the address and instruction, followed by the post amble.
Address — This sequence of bits contains the address of the decoder the packet it meant for. The Packet Start Bit terminates the preamble and indicates that the next bits are an address data byte. The first transmitted address bit shall be defined to be the most significant bit of the address data byte.
The Address alerts the device the message is intended for, usually a decoder, or a consist (two or more locomotive decoders).It also tells all other devices to ignore this packet. A two digit address is represented by a single byte, and two bytes are used for a four digit address. If the address does not match the decoder, the decoder will simply ignore the data and wait for the next preamble to be transmitted. Each data byte contains eight bits of information used for address, instruction, data, or error detection purposes. The first transmitted data bit of each data byte shall be defined to be the most significant bit of the data byte. The Instruction byte tells the device to set a function (light, bell, whistle, horn, coupler, etc.) on or off, to change to a specified speed step, to reverse direction, to emergency stop, etc. If the packet is corrupted, a decoder looking at the final byte would find the checksum included is wrong. A corrupted packet most commonly occurs if dirty wheels or track prevented the whole packet from being read properly.
The command station applies an XOR function to the address and instruction bytes, and this is appended to the packet to create the error detection byte. The decoder can perform the same function and compare the result to the error detection byte. When a decoder sees a string of 12 bits set to 1, followed by a zero, it immediately takes note. If the address byte matches the decoder’s address, it then processes the error correction byte, and if that is correct, it processes the commands it has received. By checking for errors, the decoder can reject a corrupt packet, caused by electrical noise or dirty track. The error correction scheme cannot correct an error, it can only detect that the data is corrupt.
The Reset Packet has an address and data value of zero and the XOR operation means an error byte of zero value.
Upon receiving a reset packet a mobile decoder must bring a moving locomotive to an immediate stop. In practice reset packets are normally sent as part of the programming or start up procedures to clear and power a decoder prior to transmission of programming packets. An Idle packet differs from the reset packet in that the address byte is set to 7 High (1) states, and the data packet is all Low (0) States. The idle packet is used to provide power to the track when there are no trains in motion, or no locomotives have been addressed.
DCC packets are transmitted at the rate of approximately 8000 bits per second or even higher.
Packets are only created and transmitted when the command station receives instructions to make a change. A locomotive running at a constant speed would not have any packets addressed to it unless the throttle was changed to increase or reduce speed, lights turned on or off, or in the case of sound, a button was pressed to blow the horn (or whistle). DCC systems can transmit hundreds of packets a second, which allows control of a large number of trains. A typical command station can queue up to 20 packets in the buffer, which are transmitted in sequence unless the system determines the need to transmit one packet sooner. Bandwidth is an issue taken into consideration during the design stages of the command station. Larger packets, such as those for 128 speed steps or sound commands, demand more time to send, thus they reduce the number of packets that can be sent every second.
Operating a direct current locomotive in analog mode (without a decoder) further reduces the number of packets sent in a given period.
On a large layout with a large number of locomotives in operation, this can become a problem. Properly done, several hundred trains can operate simultaneously with no noticeable problems. Higher end command stations use even more logic to determine the order packets will be sent.
Several innovations reduce the number of packets that must be sent, such as advanced consisting, which one packet addresses several decoders, decoder feedback, where a decoder acknowledges it has received a good packet, negating the need to send it again, and dual command packets, where several instructions can be combined into one packet. These techniques reduce the bandwidth demanded to operate large numbers of trains effectively. Instead of the voltage (and current) controlling the trains, a receiver (decoder) inside each locomotive listens for the commands sent out over the rails from the command station. Many systems today combine the command station and booster into the same package, so do not be concerned if you don’t have a booster. Because of this, and the whole point of DCC as a whole, it is possible to control multiple trains on the same track without having to deal with complex wiring and control panels to isolate each section of track to control each train.
The Baseline Packets are included to provide the minimum interoperability between different systems. Every Digital Decoder shall be capable of retaining and recognizing its own address for purposes of responding to Baseline Packets. It is acceptable for Digital Command Stations to restrict the number of valid addresses supported so long as this restriction is clearly and plainly labeled on the package and in the instructions.
The instruction data byte is a data byte used to transmit speed and direction information to the locomotive Digital Decoder. Bit four of byte 2 (C) by default shall contain one additional speed bit, which is the least significant speed bit. The error detection data byte is a data byte used to detect the presence of transmission errors. The contents of the Error Detection Data Byte shall be the bitwise exclusive OR of the contents of the Address Data Byte and the Instruction Data Byte in the packet concerned.
When a Digital Decoder receives a Digital Decoder Reset Packet, it shall erase all volatile memory (including any speed and direction data), and return to its normal power-up state. If the Digital Decoder is operating a locomotive at a non-zero speed when it receives a Digital Decoder Reset, it shall bring the locomotive to an immediate stop. Upon receiving this packet, Digital Decoders shall perform no new action, but shall act upon this packet as if it were a normal digital packet addressed to some other decoder. Packets sent to Digital Decoders should be repeated as frequently as possible, as a packet may have been lost due to noise or poor electrical conductivity between wheels and rails. Power may also be removed from the rails between the Packet End Bit and the Preamble of the next packet to allow for alternative command control formats.
A Digital Decoder shall be able to act upon multiple packets addressed to it, provided the time between the packet end bit of the first packet and the packet start bit of the second packet are separated by at least 5 milliseconds.
If a decoder receives a bit sequence with a missing or invalid data byte start bit, a missing or invalid packet end bit, or an incorrect error detection byte, it must recognize the next valid preamble sequence as the beginning of a new packet. Alternative command control formats are specifically allowed between the packet end bit and the start of the next preamble.
Manufacturers of decoders are encouraged to provide automatic conversion for a variety of power signals and command control formats in addition to the NMRA digital signal (per S-9.1), provided that automatic conversion to these alternate power signals can be disabled. If automatic conversion is disabled, Digital Decoders must remain in digital mode regardless of the timing of Packet Start Bits. There are numerous different controllers available and even more electronic projects with newer designs that promise to be superior. First, let us discuss the types available, then I will provide measured examples of several designs. The design is enduring if simple; a Playmobil set I bought for one of my kids I believe to have a similar design, vintage 1999. There are controllers that have a rheostat instead of an autotransformer, meaning that they change Rs in the circuit above instead of the voltage, V. The H&M controllers and my Playmobil controller have the knob arranged so that turning it one way sends the train in one direction, turning the knob in the other direction sends the train in the other direction.
Feedback contollers measure the speed using the back EMF, and try to adjust their operation moment by moment to maintain constant speed in the motor. The answer lies in the fact that when you scale things down and make a four-inch model act like a 40′ locomotive, it goes wrong.
Many enthusiasts believe that pulse controllers overheat locomotives and are responsible for burnouts and excessive brush and commutator wear.
Theory aside, there is no doubt that motors run much hotter when driven by a PWM controller. Simple theory based on resistive losses says that the heat generated with pulsed drive will be higher than the constant-dc case by a factor of the duty cycle.
A rule of thumb for electric motors is that their life is halved for every 10C (18 degrees F) rise in the armature temperature. For the scientifically-inclined reader, I refer you to a paper published in the professional literature: Scott, J.
I mentioned a Playmobil transformer that I suspect to be of the autotransformer type like the old H&M units. The waveforms would look like full-wave rectified sinewaves except for two things: The tops of the peaks are a bit flattened on account of the output impedance of the transformer, and the waveform does not fall to zero between peaks because of the back-EMF from the locomotive. Next we come to a Bachmann 6607 controller, as supplied with a number of their starter sets. The low-speed regulation is not much of an issue, because the lowest speed is not a crawl at all, more of a walk. There is nothing exciting about the waveforms from this controller; they are substantially the same as the Playmobil, except that they reduce more if you load the locomotive down. This gives the most smooth, most quiet model operation, but there is no active feedback so that the shunting performance depends upon the quality and cleanliness of track and loco. The Tech 4 controller is very impressive in appearance, and unusual in its electronic action. The drive signal consists of pulses whose width is NOT modulated, separated by a dc level that increases with the throttle setting. My only complaint is that the knobs are not center-off action, like the Duette, but reverse is achieved using a slider switch. It is clear from observing the output waveforms below that it is a thyristor-feedback design, like the Hornby basic R965 or Gaugemaster feedback designs. It works relatively well, provided its supply voltage is as advertised, or the battery inside is in good condition. The most obvious brilliant advance is that the reverse switch is mechanically interlocked with the speed control knob so that it is not possible to reverse direction except at zero thrust. Proprietary Computer interfaces differ from the popular and well-supported mainstream Comercial offerings by in a number of ways, but the key differentiator is that these interfaces typically implement custom communication and feedback techniques and protocols that are not necessarily compatible with the NMRA DCC standards. There are two fundamental ways you can interface a model railway to a computer: either via direct connection or alternatively via an indirect Interface. Direct Interfacing means running a wire from where a signal originates to where that signal needs to go.


Rewiring (to re-route a signal to a different location) can be done in software or firmware.
The RPC system is based on a shift register design and adjacent modules are connected by four signals and power.
The modules that are available from CTI are similar to the RPC units in capability, but are ready built and naturally cost rather more.
The modules are all much bigger than the RPC equivalents, and cannot be stacked adjacent (for example the trainbrain module has connectors on three of its sides). The inputs are similar to the SRI4 module for RPC in that the signal connects directly to 5V logic (actually a PIC chip) with pull-up resistors. Model railroaders seem to have some sort of Gestalt understanding of this, as evidenced by certain layouts being more universally popular than others, but there are probably more factors than you expect.
It is worth saying that obsessive detail is not always sensible, worthwhile, or attractive. While size and intricacy of track on a layout that are related to operations, and the cosmetic factors and finishing touches affect the visual appeal of a layout, these factors have no immediate relevance to the fact that it is a train layout and they do not fully define how interesting a layout is. The most obvious things that join cosmetic appearance and track work are tunnels and bridges. Both visible and invisible, allow tracks to cross, increasing density for a given length, and making the path of a train more interesting.
Varying levels of height, also called a multiplicity of levels goes hand-in-hand with bridges, hidden and visible. Concealment virtually demands tunnels and often goes along with bridges, and so barely deserves mention as a category itself, though the two are different. Topology is the mathematical study of the properties of geometric figures or solids that are not changed by homeomorphisms, such as stretching or bending.
The topology of a layout governs what trains can do logically, the routes and manoeuvres, but not the size, shape, scale or appearance.
At one time, there was a product in the American market called PC-Rail which had libraries of different track types, including Marklin Z. One oddity with many of the software packages is that they are very precise, so when you are drawing a track plan, you may end up with a little odd misalignment when you attempt to close an oval of track. Indium fact there are all kinds of spirits that walk among United States in the And many people have actually seen them.

Due to security risks and a lack of support for web standards this website does not support IE6. Decoders, which are in fact small computers (or micro controllers), respond to instructions addressed to them. A Digital Command Station transmits this information to Digital Decoders by sending a series of bits , using a digital signal. Digital Decoder Idle Packets and Digital Decoder Broadcast Stop Packets are optional for Command Stations, and required for decoders. If automatic conversion is enabled, Digital Decoders must remain in digital mode and not convert to using any alternate power signal so long as the time between Packet Start Bits is less than or equal to 30 milliseconds in duration. Even now in the 21st century, DCC is barely becoming available in Z-scale, and it is not too often worthwhile even on G-scale layouts, as the complexity is low and there is often no need for multiple locomotives operating at once. DC train controllers come in two basic types: Ones that try to fix the speed of the train, and ones that fix the DC level from the controller. The controller provides a voltage (V), the motor’s back-EMF is a voltage (M), and there are three sources of resistance between the two, that of the controller, that of the track and wires, and that of the motor. I owned a Powermaster (a US model is pictured), and it served me well for many, many years. This kind of engine has a very useful property: it acts equally well as a generator as a motor (ignoring minor losses).
The feedback controller makes the drivers life easier by keeping a train running at a known speed, even as it climbs hills. There is very little weight in a model compared to the original, different wind resistance, very different running friction and wheel slippage, yet vastly more stiction, and very little immunity to small pieces of dirt on the track, etc. On the other hand, some authors have suggested that PWM controllers do not increase the stress on motors significantly. A 10 minute comparison test will show this clearly without any more accurate measurements than the temperature sensing of your upper lip. In other words, if the PWM must use a 50% duty cycle to achieve the desired speed, resistive losses will be double what they would have been with a proportional analog controller, and if it has to use a 10% duty cycle, the losses will be 10 times greater. A squarewave signal corresponding to PWM with 50% duty cycle puts half of its energy into frequencies above dc; this fraction increases as the duty cycle falls, as does the content at higher harmonics of the pulse frequency.
In fact, the rectified mains power, sinewave-like, is a very good compromise between having pure, filtered dc, and pulses that overcome stiction and allow measurement of back EMF. Note that increased throttle gives simply an enlarged version of the previous case, with the back-EMF being a bit higher and a bit noisier, from the motor’s commutator.
This controller intends to be an autotransformer type, but it is built as a transformer with a number of taps, between which the knob switches. Looking at the first waveform below, you can see that the pulse changes from moment to moment, adjusting for the speed of the motor. This is a good design if you know the scale of the locomotive (the size of its motor), you have plenty to supply voltage, and less concern about motor heating. The mechanical design is delightful inside, giving a very cheap, very repairable, and yet very appealing controller.
It is one of the models that offer inertia, with braking via a button, plus it has an override switch for the inertia, very useful if you want to do a quick setup rather than drive for realism. I assume that the pulses are there to help defeat stiction in models, and the lower level there to control force.
The unit offers no bells and whistles, no inertia (very few units offer both feedback and inertia), and yet it is quite a satisfactory controller, especially for small layouts and shunting yards. The controller here, from a design that appeared in Silicon Chip magazine, produces results that are typical of the genre. It is a PWM design without feedback, producing a pulse drive waveform with duty cycle fixed by the position of the potentiometer. As advertised it does a good job of low-speed shunting, in comparison with the Marklin controllers. The noise on the engine back EMF, clearly visible in the RH image after the inductive flyback, is digitally filtered by the controller CPU.
It uses rectified and filtered dc, and at 19V it is much higher than the maximum required output of 12V. For example all sensors on a baseboard are directly wired to a multiplexer and a single wire is run to the control panel where a demultiplexer feeds the lamps that the sensors needed to drive. For inputs, sensors and buttons connect to SRI4 modules and track circuiting is handled directly by FTC modules. This has some advantages over the TTL signals used by RPC, especially that modules may be placed a fair distance apart (several metres). Three different plug-in pull-up resistors are supplied so you can chose the best for your sensors.
This makes them suitable for controlling solenoid motors (simply connect between a CDU and the motor).
Few people noticed the bloodshot eyes of the driver of a G-scale car I saw a friend paint once years ago, while overly simple yet overly lush trees can make a layout look better than a botanically exact alternative. The classic example is the snow scene, where a lot of nondescript white stuff and a few pine trees can make a beautiful, chilly-looking vista, while immense detail of some unappealing scenario can leave you unimpressed. If so, it will be illuminated, lights in houses, signals on, stations and streets provided with model lamp posts and so forth. It is possible to have bridges without crossing tracks, where they fulfill a largely cosmetic role, too. By adding varying levels so that the heights of the various track sections are not perceived as being on the same level, the layout becomes intricate. By using consealment techniques it is simply not possible to take in the whole thing at once, thus increasing the austhetic value of the layout. The classic example is to say that a doughnut and a tea cup are topologically equivalent, since they are both solids with one hole (the handle of the tea cup).
Topology is useful for estimating what operations a layout will support, but not how it will look, nor how large it will be.Geometric Design is another aspect of a layout.

The decoders are installed in locomotives, or are larger stationary devices that can control signals and switch machines. This sequence of bits, termed a packet, is used to encode a set of instructions that the Digital Decoder operates upon. The smaller the resistors, the closer you get to the controller’s voltage setting the motor speed. These were pretty much just heavily-made autotransformers with (in those days) selenium rectifiers. Conversely, many controllers (as will be seen below) control direction by means of a switch. In practice, this means that if it is being driven with a pulsed (or otherwise varying) electrical signal, in the moments between voltage being applied by the controller, the motor is acting as a generator, and it produces a voltage. When operating properly, the controller ensures that the setting you have on your control knob is the speed of the train, not the amount of power applied, as in the case of, say, the accelerator pedal of your car. However, a cruise control is not useful for low-speed work… not much call for shunting with an automobile. However, such tests also make it hard to believe that the heating could be bad enough to burn out a locomotive. In practice, a small locomotive, N-scale say, will run fast with 11 volts applied, and might shunt with 4 volts applied. They present inductive reactance and exhibit magnetic loss mechanisms (such as eddy-currents in the armature metal). This is roughly like trying to run your dc model with half of the energy applied as ac power instead!
Filtered (regulated) dc is not an option with feedback controllers, because it does not allow a moment now and then for the controller to measure the back-EMF. The RHS trace shows a number of waveforms at different speeds stored on the oscilloscope screen. The small yellow symbol next to the digit 1 on the RHS of the screen shows the zero-voltage or ground level.
Like the Gaugemaster, it is a feedback type that uses a thyristor (or SCR) as an electronic element switching a rectified but unfiltered source of dc, at line frequency. If anything the gain of the circuit is too high, and the control is just on the edge of stability (it is overcompensating in the image). These two pictures of load voltage show the controller dynamically changing its delivered power.


In the first image, the output voltage (controlled by the supply used with the pulser circuit) is large, and the width small, corresponding to the worst situation for engine heating.
In contrast the Gaugemaster and other line-synchronised designs run at 100 or 120Hz (for 50 or 60Hz supply frequencies). The output waveform of this contoller is a slew-limited triangle up to modest throttle, then a trapezoid with a 125Hz PRF. The system is a straightforward PWM squarewave, with no feedback, whose duty cycle varies from 0 to about 75%, so it works effectively but is not gentle on the motor. The RPC stack is a shift register which multiplexes all the inputs onto a single wire and to some kind of demultiplexor which might be a PC, or perhaps an SRO4 module. The QTU can be configured to run as manual throttles, autonomously (runs a program downloaded into it) and also to run as a computer interface board. These signals are TTL compatible (short distance only) and are used to interconnect and control the shift register. As a message circles around the loop each module receives one byte from the message, and relaces it with its input values (if it has any). This is useful with LDRs (Light Dependant Resistors) so you can match the resistor to your supply of LDR. I find that if a layout models a place that is known to the modeller but not the audience it can be a flop in the atmosphere department, probably because the modeller has memories triggered by things that are meaningless to others.
Astute readers will have noted the next section on levels in a layout; the two are closely connected, since bridges of one track over another demand having trains on multiple levels, but either can exist without the other. The topology of a layout concerns the path of the tracks, the number of sidings and their disposition, the routes and interconnectivity of the tracks, without regard to things such as tunnels, the handedness of points (switches), or the length of sidings. It describes properties like how well the track is squeezed into available area, how good a use is made of space, as well as how big it is—something that depends to a very large extent upon the scale and how tight a radius or curvature or how steep a gradient is allowed.
A large number of features and considerable running length have been put in a small area by means of folding the track around in tight circles, using curved points, and running on two levels.

If there is no Y in the column, the CV must be used for its designated purpose, but the actions taken by the decoder for a certain CV value can vary among decoder makers. Packets must be precisely defined to ensure that the intended instructions can be properly encoded and decoded. Bytes can be split into nibbles (four bit units),which represent numbers between zero and fifteen. Before the advent of solid-state electronics, these controllers were autotransformers, effectively just a transformer and a rectifier.
Sadly, cheaper controllers have high resistance (Rs), long rails or thin wires increase the trackage resistance (Rt) and smaller motors have larger resistance (Rm). This is closer to what a real locomotive motor produces, a constant force for constant throttle.
The excess heating is less pronounced at higher speeds (actually at levels closer to 100% duty cycle of the controller, meaning with its control turned up higher).
If a PWM controller applies 15 volts peak, it will run a duty cycle of between 20% and 75%, worsening losses by anything from one third to five times.
Above a certain frequency of operation, perhaps as low as a few hundred Hertz, the energy is simply lost as eddy current losses in the magnetic circuit.
Locomotive motors tend to rely on having an open casing and a draft created by the armature itself. Unfortunately, the resistance of the controller is rather high, because the unit is small and light, and yes, cheap.
In the RHS image, you can see it switching from modest power on each half-cycle to double power on alternate half-cycles. In one sense it combines the worst of both worlds (pulses that increase dissipation at low speed and no feedback) but it has an excellent interface, and the action is better than an autotransfomer type. In the second image, a lower supply is used (about 12V dc instead of rectified and filtered 16VAC) so the pulse is smaller and thus wider. It is implemented with a quad-opamp IC, giving good overload control but not much else to recommend it. Outputs from the control logic are multiplexed and sent to output modules on the RPC stack (SRO4, or DPR modules).
As the CTI system uses RS232 (9600 baud standard) any hardware with an RS232 interface can be used to build your own modules. If you see a layout and it looks like no place you would bother going to see, not characteristic of some culture or era, reminiscent of a piece or history, you are looking at an atmospheric failure. These pictures, from their boxes, show Faller bridges used to make a layout attractive without demanding rails on more than 1 level.

To make them easier to read nibbles are often represented by hexademical (base 16) numbers, from zero to F. The control knob set the voltage, and the controller had as small an output impedance as possible. This is one of the more recent, rheostat-based Duette models, lovely look, bad electrical performance.
The problem is that this does not translate well to the small scale of models; in a real train the mass is so huge that speed changes slowly, and the driver responds with throttle changes. Thus the overheating situation with a pulsed controller is worse if you are using a controller designed for higher voltages than your loco requires, for instance running a Z-scale locomotive with a PWM controller designed to handle G-scale models.
Note that the 5 times loss only occurs when the power delivered to the locomotive is less than one-tenth of its full-power load, so that it still represents half the power dissipation of full load. Worse, cooling is usually greater when the engine RPM is high, but PWM losses are greater at low speed.
Efficiency would be improved if the frequency of operation, the pulse repetition rate or PRR, was to be lowered. It is intended that it be powered from an unregulated dc voltage supply, although it ought to operate from an unfiltered one at a pinch. This makes it excellent for small end-to-end layouts, but you would not use it with a loop in a store window. The controller has adjustable inertia and braking (that can be bypassed with a front-panel switch), both centre-off and reverse-by-switch modes of operation, and it prevents sudden reversal by automating reverse selection. If you conform to the message protocol (fully documented on the web) the CTI application software (or my tcc application) will treat your hardware as if it were actually CTI modules.

To an extent this is another matter or personal preference, but it is clear that different amounts of inertia will be required to achieve realism or convenience, depending upon the scale and compression of the layout. This penalty associated with mismatch of motor and controller does not occur with non-pulsed controllers, and may account for evil tales told about PWM designs! On this basis one might feel safe to disregard the additional dissipation of a PWM controller: It can be no worse than running at a large fraction of full speed for the same amount of time. This makes for the unintuitive case that burnout is more likely at low speed with PWM drive. If that sounds scary, remember that shelf life is very long, and the duty cycle of usage is usually quite low, unless the locomotive is used somewhere like a shop window. It supplies the regulation to give a very good example of the conventional, fixed-dc controller described above. The electronic side of the design is not overly smart, but it must be cheap to manufacture, and easy to deploy world-wide, as it uses a plug-pack. Most hold in systems consumption ampere ruffle of hardware and software to detect track Rocrail capable beginning guest server multi protocol RR Automation LoCoNet software program assure Layouts keister.

To design programs that align with the essential track planning software ho n o model train scenery. You can you can easily print it just require a layout design only one i track and building. This high-frequency loss accounts for much of the excess heating in a locomotive driven with PWM.
As such, it performs better than the Playmobil type, because its output resistance is virtually zero.
