Railroad tracks are the pathways on which trains travel. They consist of two parallel steel rails that are laid on wooden or concrete ties, which help to keep the rails in place. The tracks are designed to support the weight of trains and guide them safely along their routes. The space between the rails is called the gauge, and it can vary depending on the type of train system. Railroad tracks are often found in rail yards, where trains are assembled and maintained, and they connect various locations, allowing for the efficient transport of goods and passengers across long distances.
