Model Train Transformer-Important Facts


If your new to model railroading understanding how a model train transformer works is of the utmost importance. Without question, your model train layout would be rather boring if your trains did not have the ability to negotiate the track layout which you spent so many hours designing. This is exactly what would happen, because your model train transformer is the source of power which moves your trains.

This is how your transformer actually works: Your transformer produces an electrical current that pulses through your train tracks, and this connects with the wheels on your locomotive to turn and subsequently move on these tracks. The standard current typically produced by most electrical sockets is 222 volts

You may discover that the transformer that was included with your ready to run model train kit may not suit your future needs. For example, most transformers included with these type of starter kits run on AC/DC power, and the drawback with this type of power source is that it limit’s the hobbyist ability to run more than one train on a single track.

The solution to this problem and well worth considering is DCC power for running your trains. This relatively new technology allows you to manage multiple trains at any location on your layout and you can do so directly and independently. This result is produced by the inclusion of a tiny micro-chip, known as a decoder, which must be installed in each of the hobbyist locomotives.

DCC power works by conveying a constant voltage to your train tracks continuously, and this is the opposite of how DC power works. The ability to turn lights on and off, and sound capabilities are two additional benefits for switching to this type of model train transformer. Forewarned is forearmed and the model railroader must also be aware that DC locomotive cannot be run with a DCC transformer.

With this discussion of DCC power a brief explanation of how AC and DC power works is in order as well.

DC Power

This type of power is one of the more standard ways for running locomotives, and it works in this way: The transformer conveys different levels of voltage to your track rails, which the operator has the freedom to change at will and this controls the speed by which your trains move throughout your layout. This is a suitable method for running your trains if your layout isn’t complex. If there is a problem with DC power it is that you cannot control more than one train independently. The best advice when buying your first model train kit is to look to the future and carefully consider what your future goals are for running your trains. Keep in mind that the cost for model train transformers increase with what their capable of doing.

AC Power

AC power transformers work in much the same way as do DC transformers with this exception: The direction of current changes at a higher frequency, and this will prevent the modeler from running locomotives that will run with DC power because they will not operate with AC power. This speaks to the need to do some careful research before buying any type of model train transformer.
