Introduction: Northern Europe – a hotbed for rail development

Issue 3 2014 / 4 June 2014 /

There is one standard theme currently running through the railways of Denmark, Norway, Sweden, Finland and Estonia; that theme is development, writes Craig Waters, Editor of European Railway Review.

Norway: The new Ulriken Tunnel – drill and blast or TBM?

Issue 3 2014 / 4 June 2014 /

The line between Arna and Bergen in Norway is one of the most heavily trafficked sections of single-track railway in Europe, with approximately 130 trains passing daily. This section is a bottleneck for rail traffic to and from the station and freight terminal in Bergen. The Norwegian National Rail Administration (Jernbaneverket) is currently carrying out a competitive tender procedure for the construction of the new Ulriken Tunnel between Arna and Bergen as part of the Arna–Bergen double-track project. Two alternative construction methods are envisaged: conventional drilling and blasting or the use of a tunnel boring machine (TBM). On the closing date for tenders at the end of February 2014, tenders had been received based on both methods, and the choice of method will be decided during the negotiations with the contractors. It is estimated that the total investment in the project will be NOK 3 420 million. Hans-Egil Larsen, Project Manager at Jernbaneverket provides more details.
