Since August of the same year, the Georg Mayer company from Alzey had been working on the Cramberg tunnel, the east portal of which lies south of Balduinstein.

Archduke Stephen, Palatine of Hungary, who had moved back to his County of Holzappel in 1850, sought a stately entrance building for his guests staying at the newly redesigned Schaumburg Castle,[5] although this matter was at discretion of the ruler, Adolphe, Duke of Nassau.

[6] The Fürstenzimmer ("princes’ room"), which had a separate entrance from the station forecourt as well as platform access and had 15 square metres of floor space, proved to be too small at the latest by the summer of 1863.

The district administration of the Rhein-Lahn-Kreis said that Balduinstein station was "a testimony of artistic creativity and technical activity [...] in the Lahn valley" ("ein Zeugnis des künstlerischen Schaffens und des technischen Wirkens […] im Lahntal").

[8] Deutsche Bahn AG sold the building in February 2004 to First Real Estate Grundbesitz GmbH (FRE), which became insolvent in the autumn of 2007.
