Tinnoset is a village in Notodden Municipality in Telemark county, Norway. The village is located at the southernmost end of the large lake Tinnsjå, where the river Tinnelva begins flowing south out of the lake. It is about south of the village of Rudsgrendi, about north of the village of Gransherad, and about to the west of the village of Bolkesjø.
Tinnoset Station is the terminus of the Tinnoset Line, a long railway line that went from Tinnoset to the town of Notodden. Tinnoset Station was located adjacent to the docks at the south end of lake Tinnsjå. From 1909 until 1991, these docks connected the Tinnsjø railway ferry system to the Tinnoset Line in the south. The railway ferry service crossed the lake and connected to the Rjukan Line and on to the town of Rjukan.[2] [3] [4]
