Singen (Hohentwiel) station

Deutsche Bahn officially call the station Singen (Hohentwiel). Because of its size and its significance for the district of Konstanz, the station is sometimes referred to as Singen Hauptbahnhof locally. In addition, the abbreviations Singen (Hohentw), Singen (Htw) and just Singen are used.

Singen is the starting point of the Gäu Railway (Gäubahn) to Stuttgart. On this line, the city is a stop for InterCity services between Stuttgart, Singen, Schaffhausen and Zurich. In addition, trains on the Black Forest Railway (Badische Schwarzwaldbahn), connecting Singen Offenburg and Konstanz stop in Singen. The Upper Rhine Railway (Hochrheinbahn) provides connections to Basel.

Singen owes its development from a farming village into industrial town primarily to its role as a railway junction. The railway reached the village for the first time in 1863, when the Upper Rhine Railway was completed from Basel to Konstanz (Constance). Ten years later, the Black Forest Railway was completed from Offenburg to Konstanz, connecting with the Upper Rhine Railway in Singen. The Etzwilen–Singen railway to Switzerland completed the main lines connecting with Singen.

Large Swiss companies established their German branch factories in Singen, not least because of its good rail connection. The factory workers were now brought to work in Singen in great numbers by train. A local commuter railway, the Randen Railway (Randenbahn), was built in 1912, but it was closed in 1966.

The railway used to be one of the largest employers in Singen. The first station building was soon replaced by a more solid building, which still stands with small changes. The goods yard, which formerly stood on the other side of the tracks with sidings connecting directly from the factories, soon became too small. Therefore, a new freight yard was built in 1927.

The section of the Upper Rhine Railway between Schaffhausen and Singen was electrified in 1989.
