An electric train is a type of train that is powered by electricity rather than diesel or steam. It uses electric motors to drive the wheels, which makes it more efficient and environmentally friendly. Electric trains are commonly used in urban transit systems, such as subways and trams, as well as in long-distance rail services. These trains receive electricity from overhead wires or an electrified rail. The use of electricity allows for faster acceleration and quieter operation compared to traditional trains. Many cities around the world, including Tokyo and Paris, have extensive electric train networks that help reduce traffic congestion and pollution.
