Reference Sheet UHN Holm – Nykirke

On the Vestfoldbanen line, Jernbaneverket built a new double track section between Holm and Nykirke. In the northern part, there was an interface to the existing double track section on Sande, and in the south the new line ended on Nykirke station with interface towards single track towards Tønsberg. Total length of the new double track was 14.2 km. A total of 12.4 km. of the line was built in a tunnel comprising Holmestrand station and adjacent line sections. The signalling system for the new section was delivered by Thales – ESTW L90 5, a class-B Interlocking with optical signals. The scope included necessary modifications on the Ebilock-950 Interlocking from Bombardier on the existing Sande part of the line. The new double track section was commissioned in November 2016.

Reference Sheet SignAn, SSG Sandnes – Stavanger

SSG Sandnes – Stavanger was the first work order of the Norwegian signalling frame agreement for electronic class-B interlockings – SignAn. Scope of the Project was to commission a new interlocking for the (Klepp) – Stavanger section of the Sørlands-banen line. The Project also had the responsibility to get the new IL approved internally and by the Norwegian Railway Authority (“Statens Jernbanetilsyn”).

The project comprised.:

  • Responsible for follow-up of supplier for Generic Approval of Thales IL ESTW L90 5.
  • Installation and commissioning of Thales IL (Interlocking) at Ganddal Freight Terminal
  • Installation and commissioning of Thales IL at 5 stations and 4 block posts.
  • Finalize the adaptions of other railway systems necessary for the commissioning (i.e. track works, catenary works, low voltage works).
  • Training of technical and operational personnel


prorail AS Contribution in the project (may 2012- march 2018):

Thales signed a contract with Jernbaneverket (now Bane NOR) on total system responsibility for design, engineering, installation, testing and commissioning of the new IL.

ProRail contributed with the following:

  • Planning and follow-up installation and adaption of cable routes.
  • Daily follow-up of Thales and their installation subcontractor’s.
  • Responsibility for follow up of engineering of track and catenary systems on the double track section Sandnes – Stavanger.
  • Participated in several analyzes, workshops and clarifying meetings with Thales according to generic approval.
  • Participation in several analyzes, workshops and clarifying meetings with Technology, Traffic department etc. in connection with generic and specific approval.
  • Follow-up tests done by Thales on site. This includes installation control, Pre-test and pre-SAT.
  • Participation during commissioning tests, SAT.

Verification of signalling engineering Moss station

The overall project scope was to engineer the total rebuild of Moss station on the Østfoldbanen eastern line; as part of the Intercity project Moss-Såstad; including engineering of centralized traffic control. ProRail AS scope was to do quality control and approval of the signalling drawings according to the Norwegian signalling engineering process and to provide technical support for Norwegian requirements to Danish signalling engineers.

Signalling engineering; Rudshøgda timber terminal

ProRail scope was to present possible solutions for a new freight terminal for timber on Rudshøgda stastion and engineering management and engineering of the necessary signalling works. The engineering was done according to Bane NOR signalling processes.

Engineering manager and Project Engineer; signalling projects

Signalling Engineering manager and Project Engineer working as part of the COWI engineering organization; with focus on Norwegian technical requirements and the Norwegian signalling engineering process; since main part of the engineering was done by Danish signalling engineers. Included engineering for the new double track section Arna-Bergen on the Bergensbanen line; and the new double track Intercity sections Haug-Fredrikstad and Sarpsborg-Halden on the Østfoldbanen western line. The scope also included engineering of a temporary interlocking for Bergen station.

Engineering manager signalling; IC Nykirke-Barkåker

Engineering manager for engineering of the initial signalling plan for the ERTMS-installation on the Intercity project Nykirke-Barkåker; a new double track section of the Vestfoldbanen line. Included following the complete Jernbaneverket signalling process. After completing the main scope; temporary points for construction work was included in the scope as temporary changes in the existing NSI-63 relay interlocking.

Engineering management signalling; IC Venjar-Sørli

Engineering management and approval of drawings for engineering of the detailed signalling plan for the class-B system on the Intercity project Venjar-Sørli; a new double track section of the Dovrebanen line. Included following the complete Jernbaneverket signalling process. Also included complete engineering of the modified ATC-system on the Siemens signalling system on Eidsvoll station; a part of the Gardermobanen line.

Project Engineer; signalling UAB Arna-Bergen

Project Engineer on behalf of Jernbaneverket during engineering of the signalling system for the new double track section between Arna and Bergen on the Bergensbanen line. The work scope included both temporary signalling installations and the new class-B signalling system from Thales as part of the SignAn signalling frame agreement.

Signalling Oslo S; EPC Railway Systems Follobanen

InfraNord Norge won the Railway System contract for Oslo S with the scope to engineer; install; test and commission all permanent adaptions of Oslo Central station for the new Follobanen double track line. Track works; catenary; telecom; low voltage; high voltage and signalling systems are included in the scope. ProRail AS scope is engineering of the signalling system for procurement and installation; project and site management for the signalling subproject; sub-contracting of installation contractors; installation check out and function control of the signalling system. The NSB-77 relay interlocking will be modified and will border the new Thales class-B interlocking at the new entry signal for Oslo S in the new Follobanen tunnel. The project scope will be commissioned during several phases; ending in 2022 with commissioning of the complete Follobanen line. The project requires high capacity of personnel with signalling certifications from Bane NOR.
