General circulation models, the most commonly 5 used tool for climate predictions, show an increase in precipitation due to an increase in greenhouse gases (Cubash and Meehl, 2001).

However, because of their coarse resolution, the global models are not suited to local assessments. Thus, downscaling 10 of data is required. A Linear Model (Smith and Barstad, 2004) is used to dynamically downscale oro- graphic precipitation over Western Norway from twelve General Circulation Model sim- ulations based on the A1B emissions scenario (IPCC, 2003).

The current single track has insufficient capacity, and track doubling of this section will improve the situation for goods and passenger services. The biggest part of the section passes through a tunnel under Mount Ulriken. Jernbaneverket is now constructing a new, parallel tunnel in order to increase capacity. The double track will also permit faster speeds and improve traffic management flexibility.
