The Rhenish Railway Company opened the Rheinischen Bahnhof (Rhenish station) as the terminus of the Cologne–Aachen railway (line-km 70.2) in 1841.
The current entrance building and the station concourse date from 1905 when the station was rebuilt as part of its merger with Aachen Marschierthor station, the terminus of the Aachen–Mönchengladbach railway.
In the run-up to the electrification of the station, the tracks within the station hall were rearranged in 1966.
Since then, Aachen Hauptbahnhof has had nine platform tracks, four of which are designed to enable  the transition between electrical systems: the overhead lines can be switched to use either the 15 kV/16.7 Hz AC used in Germany or the 3 kV DC used in Belgium.
A 3-S-Zentrale (a DB Station&Service station control centres) has been located in the entrance building since 2003.

All local and long-distance trains stop at Aachen Hauptbahnhof.
With the exception of ICE International, Thalys and Euregiobahn services, all trains start and end here.
The rolling stock of the NRW-Express, the Rhein-Sieg-Express and Euregiobahn are maintained in a DB Regio NRW depot to the west of the station.
