As a beginner model railroading hobbyist, wiring your railroad may seem to be a daunting task. However, model train wiring can easily be understood by grasping a few basic principles and applying these to your layout.
Once you have mastered these principles, you will be able to quickly and easily wire your own layout, and run your trains like a pro.
Connecting Your Model Train Wiring
The first thing to understand when wiring a layout is that there has to be a way to get the electrical current to the model railroad’s locomotives.
The railroad tracks are the medium through which the electrical current will be transmitted. This means that essentially the rails are acting as a positive and a negative wire that will carry the current to the locomotives.
In order to have a smooth running railroad, rail joiners are used to connect the tracks and allow the electrical current to flow through the entire model railroad layout. Therefore, in order to have an efficient model railroad, your joiners must fit tightly and be clean at each point where they join together.
If these are not kept clean and fitting tightly, there will be points along your railroad where the train will run slowly, or may not run at all. If this happens, you can clean dirty rail joiners by using a little bit of alcohol and a small Q-tip. If the rail joiners are loose, then they need to be replaced with new rail joiners.
The next thing to understand regarding model train wiring is that your controller runs the voltage which sets your train’s speed. On most controllers, there are two sets of posts for connecting wires. The first set is for the direct current, the DC terminal, and this is used to power the train itself.
The other set is the alternating current, or AC terminal. The AC terminal is used for operating accessories like crossing signals, street lamps, and building lights. It is usually very easy to connect wires to the AC and DC terminals, because these are usually clearly marked on any model railroad controller.
In addition to controlling the voltage that runs through your layout, a controller serves as an electrical converter which changes your home’s AC current into DC current, which your locomotives need to be powered with.
When wiring your track to your controller, it is important to remember to connect the wires from the tracks to the DC side of the controller, and not the AC side. Failure to do this will result in a damaged model locomotive. Remember to connect only accessories to the AC side of the controller.
Protecting Your Railroad Wiring
When wiring any model railroad layout, it is a good idea to use insulated wiring and insulated joiners to wire and join your tracks together. By using insulated wiring and insulated joiners, you will prevent possible accidents from occurring due to improper wiring, because they serve the purpose of keeping the electrical current in the tracks and wires, preventing this current from making contact with flammable materials on your layout like grass mats or structural wood pieces.
Also, the use of insulated joiners and insulated wiring helps to prevent any shorts in the track that can cause dead zones or slow zones from developing throughout the course of your railroad.
At the end of the day, the best way to make sure you are doing everything properly is to work with some form of guide. An excellent book that focuses specifically on model railroad wiring is the; Wiring Handbook For Toy Trains available from Historic Rail.
Don’t be confused by the words toy trains. In many cases model trains are simply referred to as toy trains. Compiled by Plummer, this 96 paged soft cover book is a thorough guide to understanding traditional wiring for model train layouts.
With over 60 color photographs and illustrations, it shows you how to master the basics of electricity and wiring. It shows you how to hook-up your transformers and other components. It also shows you how to solder your own wiring, how to maintain your layout, and includes a troubleshooting section too.
With a guide like this at your side you should be able to put your layout together in no time.
In conclusion, speaking to veteran railroad hobbyists about model railroad wiring can help you to acquire valuable information regarding this issue. You may also want to read through a good wiring guide like the one mentioned above, which can help you to quickly understand the fundamentals of model train wiring.
