トゥーン湖
The Lake Thun railway line is a railway line in the Swiss canton of Bern. It links the towns of Thun, Spiez and Interlaken, running principally along the southern shore of Lake Thun. The line was opened in 1893 by the Lake Thun Railway (, TSB) company, but incorporates much of the earlier Bödeli Railway () dating back to 1872.
