It is located on the Franconia Railway (German: Frankenbahn) and is a station on the network of the Stuttgart S-Bahn.

Kornwestheim passenger station was the site of a Deutsche Bahn car train loading facility until December 2007.

With the establishment of the Central Railway (Zentralbahn) of Württemberg from Stuttgart to Ludwigsburg Kornwestheim also received a station.

To relieve the Stuttgart Central Station (Zentralbahnhof), the Royal Württemberg State Railways (Königlich Württembergischen Staats-Eisenbahnen) planned a freight bypass that provided a direct link between the Eastern and Northern Railways, the Untertürkheim–Kornwestheim line.

The terrain at the Zuffenhausen end was unsuitable, but the flat ground in Kornwestheim proved to be ideal.

A locomotive shed and a military loading ramp for the Ludwigsburg regiments were built on the eastern track field.

In 1929, Deutsche Reichsbahn completed the upgrade to four tracks between Post 12 (south of Kornwestheim station) and Ludwigsburg.

In 1935, Mayor Kercher called for a new entrance building, as Kornwestheim had recently been proclaimed a city.

A few Regionalbahn services start or finish on track 7; it is also by freight trains running towards the railway bypass towards Untertürkheim.
