Rail networks are systems of interconnected railways that facilitate the movement of trains and goods across various regions. They consist of tracks, stations, and supporting infrastructure, allowing for efficient transportation of passengers and freight. Rail networks can vary in size, from local commuter lines to extensive national systems. These networks are crucial for economic development, as they provide a reliable means of transport that reduces road congestion and lowers carbon emissions. Major rail networks, such as those in Europe and North America, play a significant role in connecting cities and promoting trade, making them essential for modern society.
