Large parts of the line have been preserved. As this stretch of the Rhine forms the international boundary between Austria and Switzerland, the railway is located in both countries.As its name suggests, the railway's original purpose was to assist in the engineering works needed to regulate the Rhine in this area - the so-called Rhine Regulation.

The Alter Rhein (German pronunciation: [ˈaltɐ ˈʁaɪ̯n] ; German for Old Rhine) is the old river bed of the Alpine Rhine in St. Gallen and Vorarlberg in the Alpine Rhine Valley, which was cut off when the Rhine was straightened during the 20th century. These cut-off arms have become valuable recreational areas and a nature reserve. In 1900, the short-cut at Fussach was completed, linking the natural course of the Rhine just upstream of Höchst and St. Margrethen directly to a new outflow into Lake Constance. The old river course downstream of this point, via Rheineck to Altenrhein on the shore of Lake Constance, became known as the Alter Rhein and continues to form the border between Austria and Switzerland. The arm is navigable from the lake to Rheineck, and is used by the Swiss shipping services on the lake to reach landing stages adjacent to Rheineck railway station. In 1906, the Rheintaler Binnenkanal ("Rhine Valley Inland Canal") was dug, connecting Sennwald to St. Margrethen. In 1923, another short-cut was completed at Diepoldsau, creating another dead branch, also named Alter Rhein. The area between the Old and New Rhine forms the nature reserve Rhine Delta (not to be confused with the Rhine Delta in the Netherlands).
