ریل (rail) is a long, narrow piece of metal or wood that is used as a track for trains and other vehicles. It provides a smooth surface for wheels to roll on, allowing for efficient transportation over long distances. Rیل is essential for the operation of railways, which connect cities and regions, facilitating the movement of goods and passengers. In addition to trains, ریل can also refer to the infrastructure that supports them, including sleepers and ballast. The development of ریل systems has significantly impacted economies and societies by enabling faster travel and trade, making it a vital component of modern transportation networks.
