The Bavarian Localbahn Society (Bayerischer Localbahnverein e.V. or BLV), with its headquarters in Tegernsee, is a society that is concerned with the history of the railways in Bavaria. Localbahn (sometimes Lokalbahn; literally: 'local line') means 'branch line' and is mainly used in southern Germany and Austria in lieu of the usual term Nebenbahn. The BLV's objectives are the operation of historic trains and the collection of historically valuable railway items from Bavaria.
The society runs the Localbahn Museum in Bayerisch Eisenstein and a locomotive shed in Landshut. It also operates the museum railway Tegernsee-Schaftlach-Holzkirchen
The BLV dedicated its museum to the once common branch lines of the railway - called Vicinalbahnen, Sekundärbahnen or Localbahnen - which connected most of Bavaria in the 19th century. Many of them have now fallen prey to the structural changes or have been changed to suburban trains in the vicinity of large cities.
The museum is installed in the former engine shed of Bayerisch Eisenstein on the border to the Czech Republic. The round shed with its seven tracks as well as the two-tracked long house contain steam engines, electric and diesel locomotives, passenger coaches as well as goods wagons from 1890 to 1949. Special exhibitions cover issues such as the construction of railway lines. The open-air area has a working turntable. On some weekends the museum offers rides to Bohemia with historical steam trains. The society also owns a restored local steam train and offers rides from Landshut.
