ELS stands for 'Electric Light and Power, ' which is a type of urban railway system. It is a form of public transportation that uses electric power to move people and goods from one place to another. ELS systems are typically found in large cities, where they provide an efficient and cost-effective way to move people around. They are also used in some rural areas, where they can provide access to remote locations. ELS systems are usually composed of multiple cars that run on tracks and are powered by electricity. They are often used in conjunction with other forms of public transportation, such as buses and subways.
