A first tunnel was built on the route between 1858 and 1860. Since it was in need of renovation after more than 150 years in operation, a new parallel tunnel has been built since January 2016.

During a line closure between July 31, 2018 and September 9, 2018, the new tunnel was also connected to the existing railway infrastructure . The new tunnel went into operation on September 10, 2018. The construction costs amounted to around 100 million euros . The old tunnel has been backfilled since February 2019; the work should be completed in autumn 2019
