A railway system refers to a network of rail tracks, stations, and associated infrastructure that facilitate the transportation of passengers and freight using trains. It encompasses all elements involved in rail transportation, including the tracks that trains run on, signaling systems, rolling stock (locomotives and carriages), and supportive facilities such as maintenance depots and terminals. Railway systems can vary in scale, from local light rail systems serving urban areas to extensive intercity rail networks that span countries or continents. They are designed for efficient, safe, and reliable movement, and can be operated by public or private entities. The railway system plays a crucial role in commerce and accessibility, connecting regions and providing a sustainable mode of transport.
