KB278 Marklin Z-Scale

I have an extensive collection of older (15-20 years) Z-Scale Maerklin equipment. Can I convert the locos to Digitrax, or must I buy some other brand of loco to use Digitrax? Maybe yes, maybe no. It depends upon the size of the locomotive. We are aware of several European Z-Scale model railroads that use Digitrax. We also know of a very large Z-Scale railroad in Washington, DC that uses Digitrax. This particular railroad is a model of Swiss prototype, so the locomotives are all electric-types; there seems to be enough room inside for a decoder, especially the new DZ125 series ...

KB347 American Wire Gauge

American Wire Gauge (AWG) is a U.S. standard set of wire conductor sizes. The "gauge" is related to the diameter of the wire. The higher the gauge number, the smaller the diameter and the thinner the wire. Typical model railroad copper bus wiring is AWG number 12 or 14. Connecting wire is often 20, 22, or 24. European color coded wiring practice often calls for "9" gauge wire, or approximately 3mm diameter wire. They also use smaller wire for runs from stationary decoders to individual devices. The smaller the diameter the wire, the more resistance; this means that a larger ...

KB349 Decoder Ready Locomotives?

When purchasing a loco that says its decoder ready, exactly what is implied? Does this mean wires can be wired into the numbered locations and nothing else is needed except to remove jumpers?As with any technology, it takes time for standardized terminology to become established.  Although DCC is almost twenty years old, there are still some gray areas with descriptions.  It really depends upon the individual manufacturer, and within one manufacturer's product line there can be variances also.  There are several types of locomotive decoder installations and you may find that these terms are not applied by all manufacturers in ...

Do you have a reference for wiring Proto 2000 older geeps with a decoder (not necessarily sound)? We actually have several Life-Like Proto's sitting around for conversion to DCC, including an older GP-18, older FA's and such that date back to the days when DCC was just a twinkle in AJ's eyes. Overall, converting these locomotives will be fairly easy but there are a few things to watch for. Make sure that the decoder has enough capacity to match the current demands of the locomotive mechanism.  You must measure the stall current of the locomotive to determine this.   Make ...

KB353 Sound Decoders and the white cam lead

I don't understand what the white cam lead gets hooked up to. Some model steam locomotives are equipped with, or can be equipped with, a cam arrangement which coordinates the sound to the rotation of the drivers creating chuffing. As the wheels turn, a switch opens and closes, operating the chuff sound produced by the sound decoder. The white wire goes from the decoder to a microswitch which is operated by a cam that is mounted on the axle of one of the drivers. In operation, when the white wire senses the DCC track signal, it operates the chuff sound ...

I am installing a DH165A0 in an Athearn SD70. The head light outputs are a nominal 30 ma (with the link cut). The bulbs were of course a bit lower in their current demands and were very bright for a short while. Is there any way to lower the current output from 30ma or do I need to add a resistor in line with the bulb to drop the voltage output? Of course if it is supposed to be a regulated current output this might be a problem. The DH165A0 has a constant current source for F0F and F0R, so ...

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 ...

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 ...
