The border between the modern states of Austria and Switzerland is divided into two parts, separated by the Principality of Liechtenstein, with a total length of 180 km (110 mi).
Liechtenstein was created as an independent principality under the Peace of Pressburg (1805), although it remained nominally a member of the Confederation of the Rhine until 1866.
As shown on the National Map of Switzerland, the Swiss-Austrian-Italian tripoint is north of Piz Lad, in the Engadin.
From the Swiss-Austrian-Italian tripoint to the Dreiländerspitze, between Jamspitze and Piz Buin, the border is between the Austrian state of Tyrol and the Swiss canton of Graubünden (Grisons).
There have been plans in the past to connect the Rhätische Bahn network at Scuol-Tarasp (canton of Grisons) with the Arlberg Railway at Landeck-Zams via the Reschenscheideckbahn, but the latter was never completed.
