Train companies are businesses that operate trains for transporting passengers and freight. They manage the scheduling, maintenance, and safety of train services. These companies can be public or private and often work within specific regions or countries. Examples include Amtrak in the United States and Eurostar in Europe. Train companies typically own and maintain the tracks, stations, and rolling stock, which includes locomotives and carriages. They provide various services, such as high-speed trains, commuter trains, and freight transport. Many train companies also focus on sustainability, promoting rail travel as an eco-friendly alternative to road and air transport.
