electric multiple units (EMUs)

Electric Multiple Units (EMUs) are trains powered by electricity that have multiple connected carriages, each equipped with its own electric motors. Unlike traditional trains with a separate locomotive, EMUs distribute power across many carriages, providing better acceleration and efficiency. They are commonly used for commuter and suburban transit because they can quickly start, stop, and handle frequent stops, making them ideal for densely populated areas. EMUs run on electrified tracks using overhead wires or a third rail, reducing emissions and noise compared to diesel-powered trains.
