Economy of Liechtenstein
The economy of Liechtenstein is based roughly equally on services (especially financial services) and industry, with a small but significant agricultural sector. The country participates in a customs union with Switzerland and uses the Swiss franc as its national currency. It imports more than 85% of its energy requirements. Liechtenstein has been a member of the European Free Trade Association (EFTA) since 1991 (previously its interests had been represented by Switzerland). It also has been a member of the European Economic Area (EEA) since May 1995 and participates in the Schengen Agreement for passport-free intra-European travel.
Basel Badischer Bahnhof
The Badischer Bahnhof is located on Swiss territory, but due to the 1852 treaty between the Swiss Confederation and the state of Baden (one of the predecessors of today's Germany), the largest part of it (the platforms and the parts of the passenger tunnel that lead to the German/Swiss checkpoint) is treated as an inner-German station and is operated by the Deutsche Bahn. The shops in the station hall, however, are located in Switzerland, and the Swiss franc is used as the official currency there (although the euro is universally accepted).
