The Blauer Enzian is a named express train service that currently runs between Frankfurt in Germany and Klagenfurt in Austria. Introduced in 1951, it originally ran via the German North–South railway line between Hamburg and Munich. Labelled as an international Trans Europ Express (TEE) train, it also linked with Zell am See and Klagenfurt in Austria from 1969. Trains were operated by the Deutsche Bundesbahn (DB) and its Deutsche Bahn successor, from 1970 also by the Austrian Federal Railways (ÖBB).

The Trans Europ Express, or Trans-Europe Express (TEE), was an international first-class railway service in western and central Europe that was founded in 1957 and ceased in 1995. At the height of its operations, in 1974, the TEE network comprised 45 trains, connecting 130 different cities, from Spain in the west to Austria in the east, and from Denmark to Southern Italy.
