For topographical reasons a zig zag had to be installed in Grävenwiesbach to continue the line to Weilmünster and later to Weilburg.

After planning in 2005, the island platform at Usingen station was extended in the autumn of 2006 to accommodate trains consisting of four Linke-Hofmann-Busch VT 2E two-car railcars or three LINT 41 sets.

This was formerly the location of the loading station of the 4 km-long narrow-gauge railway to a geyserite works (now Bremthaler Quarzitwerk)[4] and a siding from Raiffeisen Waren-Zentrale Rhein-Main (an agricultural cooperative).

Usingen station is the Taunus Railway's centre of operations and is in the area where fares are set by the Rhein-Main-Verkehrsverbund (Rhine-Main Transport Association, RMV).

The trains of the Taunus Railway (RMV line 15) can use either track to run to Brandoberndorf via Grävenwiesbach or to Bad Homburg via Neu-Anspach, Wehrheim and Friedrichsdorf.

The Taunus Railway operates every half hour on weekdays from Grävenwiesbach to Bad Homburg; in addition, additional services run in the mornings and evenings in the peak hour, which operate to/from Frankfurt (Main) Hauptbahnhof and for operational reasons mainly run as RMV line 12 to/from Königstein.

On the opposite side of the entrance building is a bus station, formed of platforms 1–3.

It is currently proposed to electrify and upgrade the Taunus Railway by the end of 2022[5] to enable the extension of S-Bahn line S5 from Friedrichsdorf to Usingen.
