Grand Duchy of Baden State Railway
In 1838 the Main-Neckar Railway was planned to connect Frankfurt to Mannheim and Heidelberg. The Bensheim–Heidelberg section was opened together with the branch from Mannheim and thus the whole length of the Main-Neckar Railway was completed on 1 August 1846 in Friedrichsfeld. In order for both cities to be treated equally, a break-of-gauge station had to be built by the Main-Neckar Railway and the Grand Duchy of Baden State Railway.
