On the other hand, with the commissioning of the Brenner Base Tunnel, the east-west traffic between Munich and Salzburg could be diverted over the Munich-Mühldorf-Freilassing-Salzburg route, which would be upgraded for this purpose in the form of upgraded section 38 of the main line (Magistrale) for Europe. This involves track doubling and electrification; construction has begun. This would allow the Munich-Rosenheim railway line to absorb the additional traffic from Munich towards Brenner.
