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.

Bodensee–Toggenburg railway
The Bodensee–Toggenburg railway is a mainly single-track standard-gauge line connecting Romanshorn on Lake Constance and the Toggenburg region in Eastern Switzerland. It was built by the Bodensee-Toggenburg-Bahn (BT), a former railway company, which existed from 1910 until its merger with the "old" Südostbahn (SOB) to form the "new" Südostbahn (SOB) on 1 January 2001. Today, the line together with the Wattwil–Ebnat-Kappel section forms the eastern network of the Südostbahn.
