What is electric multiple unit train?

An electric multiple unit train, also known as an EMU, is a type of train that uses electricity as its primary source of power. It is made up of several self-propelled carriages that are interconnected and run on overhead electric wires or through a third rail system.

EMU trains are commonly used for commuter and suburban transportation, and they are known for their speed, efficiency, and reliability. They are designed to carry a large number of passengers, which is why they are often used in heavily populated urban areas.

One of the benefits of EMU trains is their energy efficiency. They use regenerative brakes that convert kinetic energy into electrical energy, which is then reused by the train. This helps to reduce energy consumption and lower costs.

There are different types of EMU trains, such as the double-decker EMU, which has two levels of seating, and the high-speed EMU, which can travel at speeds up to 300 km/h. EMU trains have become increasingly popular in many countries, especially in Europe and Asia, where they are an important part of the transportation infrastructure.
