The first station in Eutingen was opened on 1 June 1874 with the commissioning of the Nagold Valley Railway (Nagoldtalbahn).

The Free People's State of Württemberg and the Deutsche Reichsbahn signed a contract in February 1927 for the improvement of the rail link between Stuttgart via Horb and Tuttlingen to Singen.

Since then trains on the Nagold Valley Railway have operated to Horb or Tübingen, not to Eutingen.

Electrification of the line from Böblingen to Horb, including Eutingen station, was completed on 29 September 1974.

In addition, Deutsche Bahn has continued to rent large parts of the ground floor to maintain its technical equipment in operation.

Since 2006, Karlsruhe Stadtbahn line S41 has also run every two hour from Eutingen via Freudenstadt, Forbach (Schwarzwald) and Rastatt to central Karlsruhe, so the RE and Stadtbahn services provide an hourly service between Eutingen im Gäu and Freudenstadt.
