The new Hauptbahnhof was located outside the town at the time of its building at the south-eastern end of the then newly constructed ring road (the Kaiser-Friedrich-Ring and the Bismarckring), which runs in an arc to the west of the historic pentagon (Historische Fünfeck) at the centre of Wiesbaden.

[5] The modernisation should have been completed with the opening of the high-speed line to Cologne, but was postponed several times due to lack of funds.

As part of the economic stimulus package, the train shed roofs have been renovated at a cost of €35 million since late 2010.

The high pressure of ground water under parts of the city of Wiesbaden made this extremely difficult.

[8] In August 1991, the state of Hesse, the city of Wiesbaden and the Deutsche Bundesbahn agreed to a ground-level connection running from the Hauptbahnhof via a link to the east to the new line.

A major argument put forward in the assessment report was that the best way by far of generating passenger traffic would be a connection to the existing station and that only at Wiesbaden Hauptbahnhof would it be possible to give comprehensive access to public transport.

[8] A proposed branch off the link along the A 66 and connecting to the high-speed line towards Frankfurt, which would be served only by regional services has not been realized.

[8] As part of the connection to the new line, a platform in Wiesbaden station was extended to the length of long ICE trains.

The station building is connected to a five-span train-shed, originally with eleven tracks (now only ten are in operation), which are located in front of a broad vaulted concourse that extends eastward beyond the train-shed and at right angles to it to a vaulted lobby to the east of platform track 1.
