The New Lower Inn Valley railway (German: Neue Unterinntalbahn) is a partially completed double-track high-speed main line of the Austrian railways.
It forms a part of the core of the network of Austrian Federal Railways (ÖBB).
The bypass is part of Line 1 of the Trans-European Transport Networks (TEN-T).
[2] Since the timetable change on 9 December 2012, it relieves the existing Lower Inn Valley railway between Wörgl and Baumkirchen with trains able to operate at up to 250 km/h (160 mph).
It would then run through a nearly 10 km (6.2 mi)-long tunnel under the mountains of the southern Angerbergs and under the Inn, the A12 and the built-up areas of Kundl before emerging between the tracks of the existing line and running to the grade-separated junction at Radfeld.
