An electric multiple unit (EMU) is a type of train that is powered by electricity and consists of multiple carriages or coaches that are connected together. Each carriage in an EMU has its own electric motor, which allows the train to move without needing a separate locomotive. EMUs are often used for passenger services, particularly on suburban or intercity routes, because they are efficient, fast, and can accelerate quickly. They are commonly found in cities and areas with busy rail networks, providing a reliable and environmentally friendly mode of transportation.
