KB493 Digitrax AR1 or Circuitron AR-1

  Digitrax AR1 is a DCC Automatic Reversing Controller.  We have become aware of another product of a similar name that may cause our customers some confusion. Circuitron makes an automatic reversing unit called the AR-1 that is used for automatic reversing of analog powered trains. The Digitrax AR1 is not the same device and does not work in the same way.

KB992 Life Like Proto 2000 S-1 May Damage DCC

There is a potential problem using the DCC socket on the Life Like Proto2000 S-1. While the trucks and track pick-ups are isolated from the frame, there is a brass grounding lug attached to the motor's lower brush cap which makes electrical contact between the lower motor brush and the frame.  As a result if the wheels come in contact with the frame a short occurs and the decoder may be damaged! We recommend one of two work-arounds. 1) If you choose to use the 8 pin DCC plug, isolate the bottom motor brush from the frame of the locomotive ...

KB446 Customizing the DT400 Option #1 - Local/Global Stop

DT400 can be set up to handle stop commands globally or locally. The default is local control. With local stop, when the EMRG STOP Key is pressed once the loco on the active throttle will stop and when the EMRG STOP Key is pressed a second time, the loco on the other throttle knob will stop. To resume operation, use the throttle knobs to increase speed of the locos from 0. With global stop enabled, pressing the EMRG STOP Key will stop all locos on the layout and you will see the DT400’s track power indicator blinking on and off. ...

KB191 Case Study: PUTRA Kelana Jaya Rail Line - Background (Part 1 of 5)

The prototype operation that gains the most from DCC is one of those least frequently modeled today: Rapid transit. Rapid transit consists of streetcars, interurban, subway, elevated or commuter rail track and equipment. The trains are usually very short and intervals between trains are relatively brief. Lots of trains run each hour and many trains are running at the same time. All of this operation is very much like a typical model railroad. Any photograph of a major downtown in the streetcar era will have from two to ten streetcars visible with some only feet apart. Simulating this type of ...

KB125 Kato GG-1 Decoder Installation of DN163K1D

Kato N-Scale GG1 steps needed for the DN163K1D decoder Carefully remove the locomotive’s shell and light board retainer from the frame. Notice the orientation of the light board inside so that you can install the new decoder in the same orientation. Carefully remove the factory light board by sliding it toward the back of the locomotive and out from under the forward frame notches. Then gently lift the board out of the frame. Be careful not to bend or damage the motor tabs. Carefully remove the motor tabs from the factory lightboard. The motor tabs attach to the board with ...

KB285 Mars Light in a Proto 2000 PA-1

I'm trying to install a DH123D decoder in a Life like P2K PA loco and make the mars light work. HELP! Because the DH123D is a two-function decoder (front headlight, rear headlight), it may not be the best decoder choice for this locomotive. In practice, some PA's had only one headlight, thus there would be no Mars light. The DH123D would be an appropriate choice for those locomotives. Typically, eastern railroads would just have one headlight; think Pennsy and Southern Railway. Western railroads, because of higher train speeds, often used warning lights such as the Mars Light or Pyle Gyra-Light; ...

KB79 Case Study: Nemo Junction - The Railroad Part 1 of 9

Background The world is filled with places like Nemo Junction, a crossing between two railroads which is protected by a signal interlocking plant that also serves as an interchange point between these railroads. Cars destined for places to and from another railroad are exchanged at places like these. The interchange has been described as being the ideal model railroad industry because any type of car can be found there, heading toward places that are not on the model railroad itself. Nemo Junction is based upon a real place, a location in Illinois identified on the timetable of the Santa Fe ...

KB578 Using MRC RailPower 1370 with Zephyr Xtra Jump Ports

Q:  I have an MRC RailPower 1370 DC power pack.  I was wondering if that would work as a jump throttle on my Zephyr till I get my UT4 LocoNet Throttle? A:  We think that the answer is "No", but you will need to verify whether this power pack produces pure or pulsed DC power directly with MRC. Throttles used with Zephyr Xtra via the Jump Port must produce pure DC power, often referred to as "smooth" power packs. Many "advanced" analog power packs use automatic pulse injection to make model locomotives run better at slow speeds. This uses 1/2 wave AC ...

KB849 Zephyr - Jump Ports-Using DC Power Packs as DCC Throttles

DCS50’s Jump A & B ports can host two DC power packs that work as additional throttles to control DCC locomotives.You begin with an operating DCS50 attached to your layout.   In addition to the throttle built into the DCS50, you can create a LocoNet to add additional Digitrax throttles and other Digitrax devices.  Jump Ports:You can also connect up one or two smooth DC power packs as shown in the following illustration.  These power packs must also be powered, since the Zephyr jump throttle connections detect the voltage level from the individual power pack(s) and makes adjustments to the command control ...

KB521 What is "Smooth" DC?

The term smooth DC is used to describe the power provided to the layout by conventional model railroad power packs (analog transformers). Traditional model railroad power packs convert household line current into 12-18 volt current to power your model railroad. Voltage is supplied to the track, and as the voltage increases, the speed of the locomotive's motor increases, which makes it run down the tracks at faster speeds. Some power packs put out only AC (alternating current), while others put out DC (direct current) and AC (for accessories such as track switches and building lights). AC powered trains tend to ...

KB59 BDL168 - Terminology

Here are some terms that you might find useful as you work with the BDL168. Direct home wiring is a layout wiring method where each power district and its booster is electrically isolated. The track within each power district uses a "common return" wiring method for occupancy detection and/or power management. Direct home wiring is the wiring method recommended by Digitrax for safety reasons & also because it makes detection work more prototypically. Power district is the power wiring, track, components and equipment attached to that wiring, driven by a single properly isolated booster. The track for a power district ...

KB466 What is Stall Current

Stall Current is the max current draw in amps for a motor when it is stalled. This is important in determining which decoder to install in a locomotive. Why is Stall Current important? In the conversion of analog locomotives to DCC, how much current the locomotive draws is a major factor in decoder selection. Decoders are grouped by their ability to handle the electrical load that flows through them to the locomotive motor. The Ampere (Amp) is the unit of measure for electrical current used by the locomotive. The current draw of most HO can motors is between .5 and 1.5 ...

KB168 Layout Lighting and DCC

What's the best method to handle structure and street lighting with a DCC layout? If I put in bus wiring for my lighting can it interfere with the DCC signal? Unless you have stationary decoders that control the structure and street lights, there is no need for connecting these lights to your DCC wiring. In fact, doing so will add additional power consumption without any of the advantages of command control. These additional power consumers take away available power for your locomotives, controlled cars and stationary decoders. Should I use a completely different power source like an old power pack? ...

KB513 Zephyr - Non-USA Power Supply

Note: Zephyr (DCS50) has been superseded by Zephyr Xtra (DCS51) which is available in an EU version that comes with the appropriate power supply.  This article only applies to the original Zephyr (DCS50)Q: I´m a foreign model railroader, and I want to buy a Zephyr without power pack. The instruction manual says that I can use a 18 Volt DC trafo in order to power the Zephyr. Can you suggest a way to connect a Zephyr DCS 50 to German current (220/50)? A:  In the North American market, Digitrax recommends the use of a dedicated PS315 power supply or equivalent for use ...

KB129 Recommendation For Small Starter Layout

I have a 4x8 H0 scale layout.  I'm 13 years old and REALLY thinking about switching to DCC, I need to know really fast because I want to ask my parents to get it for Christmas.You wouldn't know by looking at those who edit the Tech Support Depot, but there actually was a time when we too were thirteen, and just starting out in model railroading.  In many ways, we still are thirteen years old; we just can't move as fast.  Consider this photograph from our youth: This little bit of ancient model railroad history dates back to the 1950's, ...

KB1046 Powering the DCS240

The PS615 is the Digitrax recommended power supply for the DCS240 in 5 amp mode.  For operations at 8 amps the PS2012 is the recommended power supply. When using the PS2012 special wiring considerations need to be used when powering both the DCS240 and legacy boosters from the same PS2012.  Leagacy boosters are defined as the DCS100, DCS200, DB150, DB200 or DB100.  Please see the separate article “Powering your DCS240 with a PS2012” and the additional notes below. The DCS240 may be powered either using the barrel plug connector or the screw terminals labeled “+” and “- “. The barrel ...

KB1048 Digitrax Command Control - The Future Is Now (2016 version)

Digitrax Complete Train Control By Zana & A.J. Ireland Digitrax Complete Train Control makes reliable, realistic train operation and simplified layout wiring a reality. Digital Command Control is incorporated within the Digitrax system to let you control multiple trains independently on the same section of track without blocking. In the real world, engineers control the speed and direction of real trains. Engines operate under their own power independent of the track. Each engine has its own motion characteristics like how fast it speeds up (acceleration) and how long it takes to slow down (deceleration). A locomotive's performance is influenced by ...

KB902 Scaleable Speed Stabilization (Back EMF) in Digitrax Decoders

Speed stabilization is a feature that causes the decoder to run the locomotive at a somewhat constant speed according to the throttle setting. This means that if you set your throttle to 21% of total speed, the decoder will force the motor in the locomotive to maintain a constant speed at that level no matter what the track gradient or the load on the locomotive. The SD9 is an example of a US prototype that employed a load compensating type of control technology. Many modern European locomotive prototypes use some form of load compensation of the prime-mover in response to speed ...

KB1015 Power Xtender Q & A

My sound decoder has a capacitor, why do I need a PX112? The capacitor that came with your Digitrax sound decoder is designed to hold up sound operation in the presence of brief power interruptions.  It is not designed to keep the locomotive’s motor and lights running.  Our ears are very sensitive to sound interruptions so, the capacitor on your sound decoder will prevent most of these drop outs on average quality track.  Most people don’t even notice the small pauses in a locomotive’s movement and the small flashes of the lights when the track power is interrupted.  If you ...

KB366 Some Thoughts on Decoder Installations

There was a time when every mobile decoder installation was a custom installation. In those early days, we were just feeling our way along, trying to find ways to make the existing supply of decoders fit into locomotives which had been designed in a different era. Fortunately, things have changed along the way, and in many cases, the Digitrax Decoder Selection Guide will list your locomotive. But many locomotives are not listed because they are too new or are too generic for a special listing. So, from time to time, you will have to "wing it" just a bit to ...

KB947 The Difference Among DCC Systems & DCC Companies

In response to questions about the differences among the DCC systems that are currently available from different companies, I offer the following comments & observations. You may have heard that all the systems are pretty much the same or you may have seen “comparison” charts in various DCC companies’ literature, in magazines or “analysis” on the Internet by “impartial observers.” Unfortunately, it is almost impossible to break down the system and company differences on a simple chart & the people who write the “impartial analysis” are usually not really impartial.
