Electric trains are powered by electricity, which is supplied through overhead wires or tracks. They are known for being efficient and environmentally friendly compared to diesel trains. Electric trains can accelerate quickly and maintain high speeds, making them ideal for urban transit and long-distance travel. These trains use electric motors to drive the wheels, allowing for smoother and quieter operation. Many cities around the world, such as Tokyo and Paris, have extensive electric train networks that help reduce traffic congestion and pollution. Electric trains are also commonly used in high-speed rail systems, enhancing connectivity between major cities.
