Passenger trains are vehicles designed to transport people from one location to another along railway tracks. They typically consist of multiple carriages or coaches, which can include seating areas, dining cars, and sleeping compartments. Passenger trains are an essential part of public transportation in many countries, providing a convenient and efficient way to travel over long distances. These trains can vary in speed and comfort, ranging from local commuter trains to high-speed services like the Shinkansen in Japan or the Eurostar in Europe. They are often preferred for their ability to avoid traffic congestion and provide scenic views during the journey.
