A Gau Badge was a political award of the Nazi Party, issued by the various Gauleiters of the Nazi political districts for a variety of achievements.
 Each Gau of Nazi Germany, which was a geographical region parallel to the traditional German states (known as "Länder") issued a unique Gau badge.
 Regulations for award were determined entirely by the Gauleiter as were any award degrees.
 Some Gauleiters issued single Gau badges while others awarded in degrees of bronze, silver, and gold.
 A handful of Gau badges were struck in gold with diamonds, normally ceremonially intended for Adolf Hitler.
 By default, Hitler qualified automatically for the highest degree of every Gau badge due to his status as Führer of the Nazi Party.
The Arlberg Railway (German: "Arlbergbahn" ), which connects the Austrian cities Innsbruck and Bludenz, is Austria's only "east-west" mountain railway.
 It is one of the highest standard gauge railways in Europe and the second highest in Austria, after the Brenner.
 The 135.7 km line is a highly problematic mountain railway, in part because it is threatened by avalanches, mudslides, rockfalls and floods.
 It is operated by the Austrian Federal Railways (ÖBB) and frequented by international trains, including the Orient Express.
