From the very beginning, there was a considerable amount of general freight, mainly for the loading of furniture manufactured in Kelkheim and the delivery of the required wood.

A siding was built in 1905 to the Hoffmann kiln of Heinrich Müller immediately north of the Fischbacher Straße level crossing.

At the southern end, another siding was planned to the Dichmann company on the route now used by the street of Mittelweg, but this was eventually built in 1948 as a narrow-gauge (600 mm) Feldbahn.

After the Second World War, there were other proposals, including building another siding, where the trains coming from Höchst could leave wagons in order to avoid the need for a second locomotive on the steep route to Königstein.

Until the construction of the central signal box in Hornau station in 1989, Kelkheim was also the base for train operations.

[5] The station was converted for S-Bahn-like operations in 1981, creating the current configuration with a 76 cm-high island platform and two sidings.

To make the line more attractive, it also operates today via the Taunus Railway between Frankfurt-Höchst and Frankfurt Hauptbahnhof.

The regional bus routes 263 and 804 of the Hessischen Landesbahn connect the station with Königstein, Glashütten, Liederbach, the Main-Taunus-Zentrum shopping centre in Sulzbach, Frankfurt, Kriftel and Hofheim.
