Railroad transportation involves the movement of goods and passengers using trains that run on tracks. This system is essential for connecting cities and regions, allowing for efficient travel and the transport of large quantities of freight over long distances. Trains can carry various types of cargo, including coal, automobiles, and containers, making them a vital part of the economy. The infrastructure of railroad transportation includes railway tracks, stations, and signals that help manage train operations. Trains are powered by either diesel engines or electricity, and they can travel at high speeds, making them a competitive option compared to other forms of transport.
