Railway companies are businesses that operate trains and manage railway infrastructure. They provide transportation services for passengers and freight, connecting cities and regions. These companies maintain tracks, stations, and signaling systems to ensure safe and efficient travel. Many railway companies are state-owned, while others are privately operated. They play a crucial role in the economy by facilitating trade and commuting. Notable examples include Amtrak in the United States and Deutsche Bahn in Germany, which serve millions of passengers each year.
