platform 9/10). In 1899 a third track was built for the main line. In 1902, the narrow-gauge Hercules Railway (Herkulesbahn) was opened. It carried lignite and basalt mined in the Habichtswald to Wilhelmshöhe station, where it was transferred to the state railway. Wilhelmshöhe was also an important freight depot. In 1904, the Kassel–Naumburg railway opened; this is now operated as a museum railway. Transport connections A steam tram service was opened from Königsplatz to Kassel-Wilhelmshöhe in 1877. The line was connected to the tram line to Mulang in 1900. The Hercules Railway ran to and from the Kassel-Wilhelmshöhe station from 1902. It was served by three tram lines from 1911; a fourth tram line connected later. Events A few days after the Battle of Sedan on 5 September 1870, the captive Emperor Napoleon III was brought in a Belgian saloon car from Cologne over the Deutz–Gießen railway to Wilhelmshöhe station and then taken to the castle, which was assigned to him as a residence. There, Empress Eugenie visited him incognito from 30 October to 1 November 1870, also arriving at Wilhelmshöhe station. On departure she travelled to Hanover.

He resided at the castle hotel and there organised the demobilisation of the German Army after the end of the First World War. He departed from the station on 12 February 1919. The last time the station was the focus of a state reception was on 21 May 1970, when Chancellor Willy Brandt received the Prime Minister of the German Democratic Republic, Willi Stoph, on a one-day visit. The political discussions were also held at the castle hotel. The guests arrived on a GDR government train. Structural changes in the 20th century In the 1930s, the passage under the Wilhelmshöher Allee bridge had become too narrow for the needs of the railway, which needed more tracks. But the roadway itself was too narrow for the needs of the increasing motor vehicle traffic. Therefore,
