After the First World War, the Free People's State of Württemberg sought to expand its railways.
For economic reasons, Württemberg was interested in ensuring that the traffic from Berlin to Switzerland ran through its territory and not only through the neighbouring states of Bavaria and Baden.
Württemberg sought to upgrade its part of the railway line from Berlin to Zurich via Würzburg, Stuttgart and Tuttlingen.
To this end, it entered into an agreement with Deutsche Reichsbahn on 23 February 1927, which resulted in several upgrading projects, including the construction of a new station in Tuttlingen.
It was envisaged that the Gäu Railway would be fully duplicated between Stuttgart and Tuttlingen.
The Gäu Railway would no longer continue from Tuttlingen to Immendingen, connecting to the Black Forest railway.
Rather, it was planned to build a direct north-south line from Stuttgart to the German-Swiss border at Singen.
Tuttlingen would be connected by a single-track 8.2 km long line (called the Hattinger Kurve—“Hattingen curve”), leading via Hattingen to the Black Forest Railway, so that the traffic from Stuttgart to Switzerland would no longer need to operate over the detour via Immendingen.
