Electorate of Hesse
The "Frankfurt-Hanau Railway Company" (, FHE) was founded at the initiative of the Prussian consul general to the Free City of Frankfurt, Moritz von Bethmann and with the financial support of the Gebrüder Bethmann bank of Frankfurt and the Bernus du Fay bank of Hanau. On 12 April 1843, the company received a preliminary construction permit from the Electorate of Hesse ("Kurhessen"), which was converted into a concession in 1844. The concession allowed for the compulsory purchase of the land required. Most of the line ran over the territory of the Electorate of Hesse, only the western section and the Frankfurt terminus, called "Hanauer Bahnhof" (Hanau Station) were located on the territory of the Free City of Frankfurt. Both the Electorate of Hesse and the Free City of Frankfurt were then independent states, separated by a customs boundary.
