Initially no trains crossed in Glan-Münchweiler  and it was only later used for train crossings.
Although the possibility of a railway along the Glan, connecting the Saar region and the region around Bingen, would have been obvious from a geographical perspective, the fact that in the 19th century it would have run across the territory of several countries prevented the realisation of the project for some time.
In addition, the border between Bavaria and Prussia in the middle and lower Glan valley, especially from Altenglan to Staudernheim, was very irregular, making construction difficult.

Already during the licensing of the Kusel line, there were new efforts to establish a line through the whole length of the Glan valley.
As Alsace and Lorraine were incorporated in the German Empire in 1871 as a result of the Franco-Prussian War, the fear that France would start another war in order to regain Alsace-Lorraine developed in Germany and some argued for a railway in the north-south direction along the Glan for strategic military reasons.
 Prussia, in particular supported this idea.
The first draft plan was made for the line in 1871, which essentially corresponded to the line as built, but the proposal quickly failed.
Another argument for the construction of the line was that it would create the shortest possible connection between Homburg and Bingen.
A connection to the Mannheim–Saarbrücken line at Bruchmühlbach or Hauptstuhl was considered.

 
Towards the end of the nineteenth century Bavaria finally abandoned its resistance to the construction of a strategic railway, as Franco-German relations had deteriorated significantly in the meantime.
While the Fortress of Metz had already been connected by several lines, the connection from the Rhine was very awkward.
After an option running to the south-east was eliminated, the plan for a railway from Mainz via Bad Münster along the Glan, sharing the Kusel line between Altenglan and Glan-Münchweiler  was adopted.
In 1897, the crossing loop at the station was extended to a total of 500 metres, in order to allow for the crossing of military trains ahead of the planning for the strategic line.
In 1899, Glan Munchweiler—like all stations along the line—received completion signals.
The new strategic railway was built with two tracks from the outset.
