How far apart are train tracks in the United States of America?

 The distance between train tracks, also known as the track gauge, can vary in the United States. The most common track gauge in the U.S. is 4 feet 8.5 inches, which is known as standard gauge. This gauge is used by most freight and passenger railroads in the country.

There are also narrow gauge railroads in the U.S., which have track gauges that are smaller than standard gauge. These railroads are typically used in mountainous or rural areas where it is not practical to use standard gauge tracks. The track gauges of narrow gauge railroads in the U.S. can vary, but they are typically between 2 feet 6 inches and 3 feet.

In addition, there are also some railroads in the U.S. that use broad gauge, which is a track gauge that is wider than standard gauge. These railroads are less common in the U.S. and are primarily found in the eastern part of the country. The track gauge of broad gauge railroads in the U.S. is typically around 5 feet 6 inches.

It is important to note that the track gauge can vary from one railroad to another, even within the same country.
