Electric railways are train systems that use electricity as their primary power source. They typically operate on tracks and can be found in urban areas, connecting cities and suburbs. Electric trains are known for being efficient, quiet, and environmentally friendly compared to diesel-powered trains. These railways often utilize overhead wires or electrified tracks to supply power. Subways, trams, and light rail systems are common types of electric railways, providing convenient transportation options for commuters. Many cities around the world have invested in electric railways to reduce traffic congestion and lower carbon emissions.
