The International Rhine Regulation Railway (‹See Tfd›German: Internationale Rheinregulierungsbahn) was an industrial railway situated on both banks of the Alpine Rhine canal to the south of its outfall into Lake Constance. As this stretch of the River Rhine forms the border between Austria and Switzerland, the railway is located in both countries (further north the border follows westwards along the Alter Rhein). Large parts of the system have been preserved, and part of the tracks are used as heritage railway.^[1]
