Rail systems are essential components of modern transportation, facilitating the movement of people and goods across vast distances. They include various types of trains, such as freight trains and passenger trains, which operate on a network of tracks and stations designed for efficiency and safety. These systems can be found in urban areas as subways or light rail, providing quick transit options for commuters. Additionally, long-distance rail services connect cities and regions, offering an eco-friendly alternative to road and air travel, thus contributing to sustainable urban development.
