In the mid-19th century, Tuttlingen was near the border of the Grand Duchy of Baden in the south of the Kingdom of Württemberg.
It was very conveniently situated on the so-called Swiss Post Road (Schweizer Poststraße), a major north-south road link from Stuttgart to the Swiss border near Schaffhausen.
In 1797 Johann Wolfgang von Goethe passed on this busy road from Weimar via Tuttlingen to Switzerland.
The construction of the main railways of Württemberg from 1844 to 1850 meant that the Swiss postal road lost its significance and Tuttlingen no longer had a convenient location.
This only changed with the extension of the Württemberg rail network to Tuttlingen.
In 1859, the Royal Württemberg State Railways started construction of the Upper Neckar Railway, leaving the main line at Plochingen towards Reutlingen and the Neckar valley to the southwest.
The line was opened in stages to Tübingen, Rottenburg am Neckar and Horbm reaching Rottweil on 23 July 1868, where a line was under construction connecting to at the Black Forest Railway in Baden.
This connecting line would run from Rottweil to Tuttlingen, where it was proposed that the line would continue to Immendingen in Baden.
 The Baden State Railway was also building the Black Forest Railway to Immendingen at this time.
The line to Tuttlingen was opened on 15 July 1869, connecting it to the railway network the first time, restoring the convenient position it had lost two decades ago.
