It is a through station with 3 platform tracks on the East Rhine Railway (German: Rechte Rheinstrecke) and is located in the Oberlahnstein district.

The first section of the Lahn Valley Railway was opened from Oberlahnstein to Bad Ems on 1 July 1858, but shortly afterwards it was buried by a landslide.

In the summer of 2008, the second phase of the project was completed and the Oberlahnstein–Niederlahnstein section was connected to the electronic interlocking system.

Oberlahnstein station once had an extensive system of tracks, which were mainly located in the now closed and dismantled freight yard.

The southern section of the East Rhine Railway (Koblenz–Wiesbaden–Frankfurt) was served until the beginning of the 2010/2011 timetable in December 2010 by the Loreley-Bahn (RB 10) and the Loreley-Express (RE 10), which were operated by Deutsche Bahn (DB).
