The Rapperswil Seedamm is the artificial causeway at the narrowest area of Lake Zurich between Hurden (SZ) and Rapperswil (SG). The structure contains two bridge segments and is approximately 1 kilometre (0.62 mi) long. The Seedamm carries a road and a railway across the lake, with the railway being used by the S5 and S40 lines of the S-Bahn Zürich and by the Südostbahn Voralpen Express.

The Südostbahn – commonly abbreviated to SOB – is a Swiss railway company, and a 1,435 mm standard gauge network in Central and Eastern Switzerland. It resulted from the merger of the original SOB with the Bodensee–Toggenburg railway (BT) at the end of 2001.
