N Gauge rails are by definition 9mm apart. This is regardless of the scale of the model components, which frequently ranges from 1:148 to 1:160.
Standard North American railroad tracks are 54.5 inches apart. This distance is known as the gauge of the rail.
The standard railway gauge is 1435 mm, or 4 feet 8 1/2 inches. Many other gauges are in use around the world, but the standard gauge is the most common.
If you are speaking of railroads, this means that any train can run any track. Before this, the gauge (width) of the rails were different and some trains could only travel so far. The companies got together to decide what the gauge should be for all the routes.
You should plant it 15 inches apart.
The distance between two rails in a train track is called the gauge. It depends on the company and the location. Narrow gauge rails are cheaper to build and allow a train to turn tighter corners; wide gauge allows for greater stability and therefore speed, and higher weight capacity. The most common gauge internationally is called standard gauge and is 4'8" (1422mm). Other common gauges are: * 5 ' 6 " (1676 mm) * 5 ' 3 " (1600 mm) * 5 ' (1524 mm) * 4 ' 8½ " (1435 mm) * 3 ' 6 " (1067 mm) * 3 ' 3⅜ "(1000 mm) There is a myth that the distance between the wheels for is related to the width of two horses or oxen pulling a cart. It is untrue, but makes for a good story.
