A few weeks later, on 16 July 1870, the last passenger train ran from Sarreguemines, subjected to stone-throwing by the French during the lead up to the Franco-Prussian War.

After the Franco-Prussian War 1870–1871, this plan lost its importance as the Luxembourg–Metz–Basel railway line was now entirely under German control.

As the rest of the station is not electrified, it can be run on the German catenary supply system without changing voltage.

Until 1945, there was also a siding from the Palatine Ludwig Railway to Römerkastell, but this was not rebuilt after the destruction of a road bridge during the war.

[3] A railway bridge was built over the River Saar in 1975, especially to connect to the German operations centre of Peugeot in the Güdingen/Unner district.

Kleinblittersdorf station has been rebuilt in recent years and a third terminating track has been installed, which can also be used by Saarbahn trains in coupled sets.

The line becomes a single track before the station and crosses the Saar and the border with France over the Prussian bridge.

The formerly extensive freight operations (mainly coal trains to France) is confined to and from the Halberg iron works and the Halberg-Guss company in Brebach.

In addition, several times a day broken slag is carried from the Saarstahl underground mine in Auersmacher to Völklingen.
