Bodenseegürtelbahn

Bodenseegürtelbahn. The Bodenseegürtelbahn is a regional railway line in southern Germany and Switzerland that skirts the northern shore of Lake Constance. Connecting the major towns of Radolfzell and Friedrichshafen, it serves as a vital transport link for the Bodensee region, facilitating tourism and local commuter traffic. The line is operated by DB Regio and the Swiss company Thurbo, integrating cross-border rail services within the Lake Constance area.

History

The construction of the Bodenseegürtelbahn was driven by the economic and strategic interests of the Kingdom of Württemberg and the Grand Duchy of Baden in the late 19th century, aiming to better connect their territories around Lake Constance. The line was built in sections, with the segment from Friedrichshafen to Überlingen opening in 1901 under the auspices of the Royal Württemberg State Railways. The western section from Überlingen to Radolfzell, including the challenging route along the Überlinger See, was completed by 1905 by the Grand Duchy of Baden State Railway. Key engineering works included the construction of several tunnels and the iconic bridge at the Gnadensee. The line was electrified in the 1970s as part of the modernization of the Bodensee rail network, and it has since been integrated into the cross-border Seehas and EuroCity service networks.

Route and stations

The 72.5-kilometer route begins at Radolfzell, a major railway junction on the High Rhine Railway line from Basel to Konstanz. From there, it travels eastward, closely following the shoreline of the Überlinger See, a northwestern finger of Lake Constance. Major intermediate stations include Stockach, known for its connection to the Hegau region, Überlingen with its historic town center, and Meersburg, accessible via a ferry link from Konstanz. The line passes through picturesque landscapes near Salem Abbey and the Linzgau region before reaching its terminus at Friedrichshafen Hauptbahnhof, a key node for services to Ulm, Ravensburg, and Lindau. Other notable stops serve communities like Markdorf, Immenstaad am Bodensee, and the Mainau island ferry terminal.

Operations and rolling stock

Scheduled passenger services on the Bodenseegütelbahn are primarily operated by DB Regio Baden-Württemberg and the Swiss railway company Thurbo, a subsidiary of SBB and DB. The core service is the Regional-Express line RE 5 (Seehas), which provides frequent connections between Radolfzell and Friedrichshafen, often continuing to Aulendorf or Ravensburg. Rolling stock typically consists of modern electric multiple units like the DB Class 425 and DB Class 426, as well as Stadler FLIRT units operated by Thurbo. The line also hosts occasional international EuroCity trains linking Zurich with cities like Munich and Vienna, and it is integrated into the Bodensee-Oberschwaben Verkehrsverbund (bodo) tariff system.

Significance and future prospects

The Bodenseegürtelbahn is of significant economic and touristic importance, providing a scenic and efficient alternative to road travel along the often-congested Bundesstraße 31. It is a backbone of the regional public transport network, supporting daily commuters to industrial centers like Friedrichshafen, home to ZF Friedrichshafen and historical Zeppelin facilities, and bolstering tourism to sites such as Meersburg Castle and the Birnau pilgrimage church. Future prospects include ongoing discussions about potential double-tracking of sections to increase capacity and the further integration of the line into the Bodensee-S-Bahn concept, which aims to create a high-frequency, cross-border rail network around Lake Constance involving Austria, Switzerland, and Germany.
