How to install easy reliable model train track wiring on your layout Model Railroader magazine Executive Editor Andy Sperandeo shows you how he makes the track on his home model railroad layout electrically reliable. He’ll show you how he solders wire feeders to the rails, bus wires, and track switches for good contact and smooth operation. Follow Andy’s tips and you’ll be on your way to trouble-free opeation on your own layout, whether it’s a 4×8 or a large layout like Andy’s or Model Railroader’s MR&T.

Model Railroad wiring help?

Question by : Model Railroad wiring help?
i have about 90 feet of track, 2 45 foot mainlines, when i run the train around, the train will slow down, sometimes to a stop, right before a power lead, i put one every 2 pieces of track. Does anybody know what is causing this, or how i can correct it?

Answer by Wingman
It sounds like you have a polarity problem.
Check all the wires.

If you have one set reversed, the track will act like a resistor and cancel out the power about midway between two of the connection points,

All the wires on the outside rail should be one polarity and all the wires on the inside rail will be the other polarity.

model railroad conventional wiring and electric dimmer switches?

Question by chinatrain99: model railroad conventional wiring and electric dimmer switches?
I have an O scale layout and using conventional wiring. I have a section of track that is “blocked” and current is controlled to this section using a regular house switch. I would like to divide sections of track and run them at different speeds using the same transformer. Since I got by using a regular house switch to control power, why could’nt I use a dimmer switch to direct the amount of power on particular sections of track. This way, I can run more independently without having transformers everywhere. Anyone else done this?

Answer by Wdlane
For some reason unknown to me house dimmer switches do not have the same effect on controlling the speed of motors as it does to dim light bulbs. You are going off in the wrong direction.

Almost ALL serious model railroaders are using DCC now. The track power is constant and live at all times. DCC is significantly easier then to have to wire many block sections. Decoders in each loco give you complete independent control without having to worry about block controls. Check out NCE DCC. They have everything to get you started.

Soldering Rails on an HO Model Railroad Layout – Wiring Part 1

This is my very first instructional video on building my model train layout. I know it is not perfect, I have things running out of the shot, and some other issues, but this was done with a Canon Digital still cam that takes videos. If I get a good response, I am going to do more details on how I build my layout. I learned a lot in this first video, and how to make the rest much better, plus I am shopping for a good digital camera to make them oh so sweet! This video is about how to prepare and wire your model train layout above the main board. A lot of people wire their layout below the main board, and they crawl under it, but I cannot since I am in a wheelchair. So I have wired this on the table, but it will be all below the landscape. All of the wires will feed back to a main panel, so I can make changes or additions on the fly, from a simple panel. I will be putting wires all throughout the layout, for stuff I have, and for future use, that way, I can pull out wires when I need them for new cool stuff. This layout is going to have automated crossing gates, a wig wag signal, and oh, so much more. Follow me in my journey while I build this cool layout with lots of bells and whistles, literally!!
