Horrem station was opened in 1841 at line-km 18.7.
It was converted into an S-Bahn station in 2002.
The Erft Railway branches off from the Cologne-Aachen high-speed line at the station.
It has two island platform tracks for operations on the Erft Railway and four platform tracks and three through tracks for operations on the high-speed line.
Until 2001, Horrem station had a freight yard to its north.
There are commuter parking spaces in this area.
The forecourt and entrance building were fundamentally rebuilt from 2010 to 2014.
A "green station" was built, with CO₂-neutral operations.
This involved the installation of photovoltaic and geothermal systems and the use of ecological building materials.
There are now a waiting room, a kiosk and a bookshop in the entrance building.

There is a tectonic fault in the area of Horrem station.
The long-distance tracks pass over this on a special structure that is underground and can hydraulically compensate for earth movements.
The other tracks have special rail joints at this point.
