What is the revised budget of Semmering railway?
The Semmering Base Tunnel is the new railway tunnel under the Semmering pass in Austria, built by OBB since 2012 and expected to open in 2030. ORF Niederoesterreich reported on 15 April 2022 that the costs would rise to about 3.9 billion euros from the 3.5 billion previously estimated, because of a geological fault zone, a very complicated rock structure and rising energy and construction prices.
