How Do You Wire & Scale A Model Train Layout?
In model railroading, you choose the scale by the track and equipment you buy. HO scale is the most popular scale because you can accomplish a lot of railroading in a relatively small space. Wiring for any scale that uses two tracks starts with a basic concept of one wire to each track rail. But, it gets complicated quickly as you increase the size and complexity of your layout’s design. Choose your scale based on the size of space available for your layout. O scale demands a large amount of space for anything more than a toy train layout. G Gauge track, which actually carries several several scales of large trains, is best used for garden railroads. HO, half of O at a ratio of 1:87, is the most popular scale for model railroads. Run wire to each of the two track rails from a model railroad powerpack that provides direct current to each of the two rails. On a small layout, where you only run one train at a time, you may only need one connection. Insert a double pole, double throw toggl
