Badische Hauptbahn
Lörrach station was opened in 1862 as part of the first private railway in the Grand Duchy of Baden, which was built by the Wiese Valley Railway Company ("Wiesenthalbahn-Gesellschaft"). The line ran from the Basel Baden station in Basel, where it connected to the Baden Mainline, to Schopfheim. It was extended to Zell in 1876. The first test run was carried out on 10 May 1862 and on 5 June the line was formally opened in the presence of the Grand Duke Friedrich of Baden. In the 1860s, before the opening of the line, the location the Lörrach station was a controversial issue. Technical and financial issues eventually led to the selection of its current location just north of Rheinfelder Straße (now Wallbrunnstraße). The Grand Duchy of Baden State Railway acquired the line and station as of 1 January 1889. The first station building was built in 1862 and it was rebuilt in 1905.
