rail
Rail refers to a system of tracks made of steel or other materials that trains run on. It is a crucial part of the transportation infrastructure, allowing for the movement of goods and passengers over long distances. Rail systems can be found in many forms, including freight trains that carry cargo and passenger trains that transport people.
The rail network is often divided into different categories, such as light rail for urban transit and high-speed rail for rapid intercity travel. Rail transport is known for being energy-efficient and can reduce road congestion, making it an important option for sustainable transportation.
