The €127m project was funded with the aid of a €106m grant from the German federal government and is a key component of a broader upgrade of the 141km Munich - Mühldorf - Freilassing - Salzburg line, which includes electrification.

The work included upgrading of track for 160km/h operation, the renewal of 36 switches, replacement of 11 bridges, and installation of 7.5km of noise barriers. A new bridge was constructed across the River Inn and Tüssling station has been rebuilt to provide barrier-free access.

The line carries significant volumes of freight from the chemical works at Burghausen as well as frequent regional passenger services.
