Friedrichshafen Stadt station was dedicated on 8 November 1847 as the first station on Lake Constance with the opening of the first section of the Württemberg Southern Railway from Ravensburg to Friedrichshafen. This meant that the
Kingdom of Württemberg had achieved its goal of completing the first railway to Lake Constance ahead of
Bavaria and
Baden. The station building was built between 1846 and 1848 by the architect Ludwig Friedrich von Gaab. On 26 May 1849, the Southern Railway was extended to
Biberach an der Riss and on 1 June 1850 to Ulm. With the completion of
Fils Valley Railway from Ulm to
Stuttgart on 29 June 1850, Friedrichshafen and the Southern Railway were connected to the rest of the Württemberg railway network, allowing a continuous service from
Heilbronn to Friedrichshafen. On 1 October 1899, the first piece of the Bodenseegürtel Railway (Lake Constance Belt Railway) was opened from
Lindau to Friedrichshafen Stadt and opened and on 2 October 1901 the line was continued from Friedrichshafen to
Überlingen, which had been connected since 1895 to
Singen via
Radolfzell. Two wings were added to the station building for the Bodenseegürtel Railway, which connected Bavaria, Württemberg and Baden. The Southern Railway was duplicated from 1905 to 1913. On 2 June 1922, the
Württembergische Nebenbahnen AG (Württemberg Secondary Railways Company) commenced operations on the Teuringen Valley Railway (
Teuringertal-Bahn) to
Oberteuringen. Already in May 1923 it had to close its operations for financial reasons, before they could be restarted in 1924 by the
Teuringertal-Bahn GmbH. In the Second World War the west wing was destroyed in an air raid on 20 July 1944; it was rebuilt after the war in its original form. Passenger services on the Teuringen Valley Railway were closed on 23 May 1954 and freight traffic ended on 15 February 1960. The section from Friedrichshafen Stadt to the former Friedrichshafen-
Zahnradfabrik station continues to operate as a siding. The lines from Ulm and Lindau have been electrified since December 2021. ==Rail operations==
