The term 'Subway Alternatives' can refer to a variety of transportation options that are available as an alternative to taking the subway. One such option is ELS, which stands for Electric Light Rail Systems. These systems are powered by electricity and typically run on elevated tracks, allowing them to travel faster than traditional subways. They are also more efficient and cost-effective than subways, making them a popular choice for many cities. Additionally, they are often quieter and more comfortable than subways, making them a desirable option for commuters.
