A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.

There is no general agreement either on what geographic area constitutes Central Europe, nor on how to further subdivide it geographically. At times, the term "Central Europe" denotes a geographic definition as the Danube region in the heart of the continent, including the language and culture areas which are today included in the states of Croatia, the Czech Republic, Hungary, Poland, Romania, Serbia, Slovakia, Slovenia and usually also Austria and Germany, but never Russia and other countries of the former Soviet Union towards the Ural mountains. Depending on context, Central European countries are sometimes grouped as Eastern or Western European countries, collectively or individually but some place them in Eastern Europe instead for instance Austria can be referred to as Central European, as well as Eastern European or Western European and Slovenia can sometimes be placed in either Southeastern or Eastern Europe. The 15 countries comprising this subregion are Austria, Belgium, the Czech Republic, Denmark, France, Germany, Hungary, Ireland, Liechtenstein, Luxembourg, the Netherlands, Poland, Slovakia, Switzerland and the United Kingdom.
