Electric traction refers to the use of electric power to drive vehicles, primarily trains and trams. This method utilizes electric motors, which are more efficient and environmentally friendly compared to traditional diesel engines. Electric traction systems often rely on overhead wires or electrified tracks to supply power, allowing for smoother and faster transportation. The benefits of electric traction include reduced air pollution, lower operating costs, and the ability to handle higher passenger volumes. Many urban transit systems, such as subways and light rail, utilize electric traction to provide reliable and efficient service to commuters.
