Badische Hauptbahn
When the Baden Mainline was built between Mannheim and Basel, the original Karlsruhe station was built on Kriegsstraße between Ettlinger Tor and Mendelssohnplatz about 500 metres south of Karlsruher Marktplatz, the central square of Karlsruhe. The station was designed by Friedrich Eisenlohr and it was opened on 1 April 1843 with two platforms. From the beginning, it was designed as a through station. South of the station there was a locomotive depot and to its east there was a freight yard and a central workshop.
