The neo-classical building is east of the tracks and originally had five parallel portals, but it was subsequently extended to the south.

This small building has a ground storey built of brick, while the signal box floor is cantilevered and provided with large windows.

About 250 metres north of the station is another signal box built in 1925, also for the Lower Westerwald Railway.

Staffel station is located in the network of the Rhein-Main-Verkehrsverbund (Rhine-Main Transport Association, RMV).

Staffel thus has rail links to Diez, Elz, Hadamar, Dornenburg, Westerburg, Altenkirchen, Au (Sieg), Montabaur and Siershahn, as well as central Limburg.
