[4] The line was extended to the Alsatian town of Colmar with the construction of railway bridge over the Rhine in 1878.

The private Kaiserstuhl Railway was opened from Breisach to Gottenheim via Endingen and Riegel in 1895.

Since Alsace was no longer part of the German Empire from 1918, Breisach became a border station between Germany and France.

[6] The Breisach Railway Bridge was blown up by German troops in February 1945 at the end of the Second World War.

On 1 June 1997, passenger services on the Breisach Railway were taken over by the Breisgau-S-Bahn (BSB), which was founded in 1996 as a subsidiary of Südwestdeutsche Verkehrs-Aktiengesellschaft (SWEG) and Freiburger Verkehrs AG (VAG), each holding 50%.

[7] The rather stately and somewhat oversized entrance building of Breisach station was built in 1913/14 from Kaiserstühl basalt.

DB Regio has operated Breisgau S-Bahn service to Freiburg, continuing on weekdays to Titisee, Seebrugg and Villingen, since December 2019.
