Inter-city rail services are express passenger train services that run services that connect cities over longer distances than commuter or regional trains. There is no precise definition of inter-city rail; its meaning may vary from country to country. Most broadly, it can include any rail services that are neither short-distance commuter rail trains within one city area, nor slow regional rail trains calling at all stations and covering local journeys only. Most typically, an inter-city train is an express train with limited stops and comfortable carriages to serve long-distance travel.
