Brenner Railway currently considered to have insufficient capacity. Moreover, its steep grades, tight radius bends and the need to change locomotive engines at Brenner due to two different electrical systems as used in Austria and Italy mean that the average travel speed is low. For these reasons, the creation of a new line is planned from Verona to Munich via Innsbruck. At the heart of this project lies a 55 kilometre-long tunnel between Franzensfeste and Innsbruck, known as the Brenner Base Tunnel. The maximum grade on the track is 31 per thousand. The minimum curve radius is 264 metres. The highest point
Duran Pass km, with a maximum gradient of 14%. Duran Pass The Duran Pass () (el. 1601 m.) is a high mountain pass in the Dolomites in the province of Belluno in Italy. It is situated between the municipality of La Valle Agordina and Zoldo Alto; it connects Agordo in the Cordevole valley and Pralongo in the Zoldo valley. The pass road is SS 347.
