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.
Standard North American railroad tracks are 54.5 inches apart. This distance is known as the gauge of the rail.
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.

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.
Yes, if there is no other force acting upon the railroad track then you would be able to hear the train about a mile away. Unfortunately this is dangerous because there is no way to tell exactly how far away the train is.
Read Paulo Coelho book called The Zahir. Pretty much explains it perfectly.
It depends on the time period. At one point there was right around 2.4 times more railroad track in the north than in the south. In 1861, the north had about 22,000 miles of track and the south had 9,500 miles of track.
Far Rockaway Branch Railroad was created in 1868.
