The railway line between Saint-Louis and Huningue (French: Ligne de Saint-Louis à Huningue) is a French 3 km long railway located in the Haut-Rhin department of the Grand Est.
[1] In the old nomenclature of the east region of the SNCF, the line was amalgamated with the Waldighoffen–Saint-Louis-La Chaussée railway.
[2] The Saint-Louis au Rhin railway was opened on 11 February 1878 and was prolonged along the Rhine river to Weil am Rhein.
Due to limited demand for passenger and freight service, the railway bridge in Huningue across the Rhine was removed in 1937.
[3] A SNCF train schedule in 2019 indicated that the station in Huningue include an industrial spur.
