Rail transport in Liechtenstein
Liechtenstein's one railway line, the Feldkirch–Buchs railway, is operated by Austrian Federal Railways (ÖBB). As such, it represents an exception to the more usual Liechtenstein practice of cooperating closely with Switzerland, as in the case of the principality's use of the Swiss franc as its currency and its membership of a common customs area with its western neighbour.
