IC meaning in Governmental ?

Inter-city rail services are express passenger train services that cover 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.

Inter-city rail sometimes provides international services. This is most prevalent in Europe, due to the close proximity of its 50 countries in a 10,180,000 square kilometre (3,930,000 sq mi) area. Eurostar and EuroCity are examples of this. In many European countries the word "InterCity" or "Inter-City" is an official brand name for a network of regular-interval, relatively long-distance train services that meet certain criteria of speed and comfort. This use of the term appeared in the United Kingdom in the 1960s and has been widely imitated.
