Railway vehicles are specialized modes of transportation designed to run on tracks. They include various types such as locomotives, which provide the power to move the train, and passenger cars, which carry people. Other types include freight cars, used for transporting goods, and maintenance-of-way vehicles, which help maintain the railway infrastructure. These vehicles are typically made of steel or aluminum for durability and safety. They operate on a network of railways that connect cities and regions, making them an essential part of public transport and logistics. The design and technology of railway vehicles continue to evolve for efficiency and sustainability.
