An electric railway is a type of train system that uses electricity as its primary power source. These railways typically run on tracks and can be found in urban areas, connecting cities and suburbs. Electric trains are known for being efficient, fast, and environmentally friendly compared to diesel-powered trains. Electric railways can include various systems, such as trams, light rail, and subways. They often utilize overhead wires or an electrified rail to supply power. Many cities around the world have adopted electric railways to improve public transportation and reduce traffic congestion.
