Train services refer to the transportation of passengers and goods using trains on railway networks. These services can vary in speed, frequency, and comfort, ranging from local commuter trains to high-speed intercity trains. Train services are an essential part of public transport in many countries, providing an efficient and eco-friendly way to travel. In addition to passenger transport, train services also include freight trains that carry cargo across long distances. Many train services are operated by national or regional railway companies, such as Amtrak in the United States or Eurostar in Europe. These services help connect cities and regions, promoting economic growth and accessibility.
