Interurban rail refers to train services that connect different cities and towns, typically covering longer distances than local commuter trains. These trains are designed to provide efficient transportation for passengers traveling between urban areas, often featuring fewer stops and higher speeds. Interurban rail systems can be found in various countries and are an essential part of public transportation networks. Many interurban rail systems utilize electric or diesel-powered trains, offering a more environmentally friendly alternative to car travel. Examples of interurban rail include the Amtrak services in the United States and the Shinkansen in Japan, both of which facilitate quick and convenient travel between major cities.
