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 are commonly used in many countries around the world, including Japan with its famous Shinkansen and Europe with its extensive high-speed rail networks. Electric trains produce less noise and air pollution, contributing to cleaner cities and reducing the carbon footprint of public transportation.
