Baden Mainline
Even when the Baden Mainline was being built, plans were already being formulated to link up with the Swiss railway network. This was not achieved until the bridge at Waldshut over the river Rhine, built by Robert Gerwig, was completed on 18 August 1859. Other links were made in 1863 at Schaffhausen, in 1871 at Konstanz and in 1875 at Singen. The Basle link line, which connected Baden station on the east of the Rhine with the Central station west of the Rhine, was opened in 1873. Today it is the most important railway connexion between Germany and Switzerland.
