TinnosetNotodden

TinnosetNotodden was a proposed railway line in Norway intended to connect the Tinnoset line, which served the Rjukan–Notodden industrial area, with the Vestfold Line. The primary goal was to facilitate the transport of goods, particularly fertilizers produced by Norsk Hydro, from the Tinnoset area to the port of Larvik.

The project was conceived in the early 20th century as part of the expansion and modernization of Norway's railway network. The Tinnoset line itself was a significant engineering feat, including a ferry connection across Lake Tinn, and the TinnosetNotodden project aimed to streamline the onward journey of its cargo. Discussions and planning for this connection took place over several years, with various routes considered.

Ultimately, the TinnosetNotodden railway was never built. Several factors contributed to its cancellation, including evolving transportation strategies, economic considerations, and potentially the completion of alternative transport solutions or infrastructure developments elsewhere. The industrial activities in the Rjukan–Notodden region eventually found other means of transport for their products, rendering the proposed direct rail link unnecessary. While the line was a subject of serious consideration and planning, it remains a historical footnote in Norwegian railway development.
