Building the "Drammenstunnelen"

An historic railway development project is currently underway in Drammen. Bane NOR is building a new double track from Drammen to Kobbervikdalen and making sure that the city gets stations fit for the future. You can read about the works that will take place from the summer of 2021 onwards here.

On this page you will find all of the information we distribute to the public within the borders of the old Drammen Municipality in the summer of 2021. The information will be updated in the event of changes. You can also open or download the brochure at the bottom of the page.

This provides information about ongoing works, what will be happening during the summer, and what works we will be carrying out in the autumn. 

Work on and near Drammen Station 

Works in 2021 

During the winter and in the run up to summer, we upgraded the technical railway systems around Gulskogen Station. In May, we replaced 550 metres of double track to the west of Gulskogen Station to allow trains to pass each other here.

We will also be taking steps at Drammen Station to make space for the new concrete tunnel we are building.

The concrete tunnel will become the first section of the Drammen Tunnel, which will end in Skoger. From Drammen Station, the Vestfold Line will enter this tunnel at Nedre Strøm. From here the Vesfold Line will run through the Drammen Tunnel and emerge in Skoger. Drammen Station will be closed for six weeks in the summer of 2021. Three of these weeks will be spent on these preparatory works.

Illustration showing where work will take place in the summer.

  1. The Sundhaugen train stabling area will be demolished in the period 3-22 July. We will also remove the track in the Sundhaugen train stabling area at that time.
  2. Once the track into the stabling area has been removed, we will install the remaining sheet pile retaining walls for the new Vestfold Line just to the north of the construction site at Nedre Strøm in the period 7-16 July. The sheet piling work will take place during the day from 07:00 to 19:00.
  3. A temporary new stabling area will be constructed on the site of the old freight terminal. This will be completed and ready for use in Easter 2022. Trains that were previously stabled at Skamarken and Drammen Station at night will use the temporary new stabling area at Nybyen during the construction period at Drammen Station.
  4. Parts of the old freight terminal will be demolished to make way for the temporary new stabling area. The oldest building is listed and will be left standing, but we will remove the reception hall and various more recent additions currently on the site. The newest addition towards the east will remain standing during the project period and be used as project facilities before subsequently being demolished. Preparatory work on water, drainage and electricity installations started in June this year. The large buildings will be demolished in connection with the upgrading of Drammen Station. The temporary new stabling area in Nybyen will be closed and prepared for future urban development upon the completion of our work.
  5. We need to widen the Grønland underpass in order to establish three tracks between Drammen Station and Sundland. This means that the Grønland underpass will be closed to pedestrians and cyclists for a period of time. Because of this, we need to construct an alternative pedestrian and cycle path across the track area. This will run from Børsemakergata to the Bus Terminal, as illustrated. In the summer, we will start work on the foundations of the temporary pedestrian bridge over the track.
  6. Bane NOR is constructing a new surface water pipeline for Drammen Municipality here. Work will start at Strømsø Perspektiv at the end of August 2021, before we work our way southwards. According to the schedule, we will pass Grønland in October, the Nettbuss Site in November, and Kreftings Gate and Griffenfelds Gate in December. The surface water pipeline is needed to carry surface water past the railway line efficiently. It will drain 8,000 litres of water per second – compared with the current stream, Flisebekken, which can drain 1,000 litres per second. The construction will mean that traffic will need to be re-routed for periods of time at Grønland, Strømsø Perspektiv, the Nettbuss Site, and Kreftings Gate.
  7. Next summer we will demolish the access route to City Bridge over the track area. The temporary pedestrian bridge over the Drammen River will be completed and ready for use before this. We will start constructing the foundations of the temporary city bridge at Jernbanegata 2. The ‘Kiss n’ ride’ area will not be accessible until the new city bridge has opened in 2025.
  8. The Nettbuss Site will be used as a laydown area and construction site. Unfortunately, this will result in the loss of some parking spaces.

Works in 2022

In 2022, we will, together with Drammen Municipality, each demolish our part of City Bridge. City Bridge will be demolished before the summer, while the section that stretches over the railway track will be demolished in July. At this time, we will also upgrade the technical railway systems around Brakerøya Station.

We will construct a temporary pedestrian bridge to provide access over the river while a new bridge is being built. This is scheduled to open after Easter in April 2022. During the same period, we will construct a temporary stabling area for rolling stock in Nybyen. This work will be completed during the summer of 2022.

Works in 2023

Work on the actual platform area will start in 2023. The station will close again in Easter 2023 so that we can demolish today’s tracks 4, 5 and 6 and corresponding platforms. The station will be divided lengthwise and for the next year train traffic will use today’s tracks 1, 2 and 3. At the same time we will construct two new platforms and corresponding tracks. This will be done within a six-week period while the station is closed in the summer of 2023.

Works in 2024

The first half of the new station towards the river will be completed during the winter and in the lead up to the summer of 2024. Train traffic will then be transferred to the three new tracks and two new platforms. This work will take place in a four-week period during the summer closure in 2024.  The current tracks 1, 2 and 3 will be removed during the same period. We will then start work on constructing the other half of the station with two new platforms and corresponding tracks. 

Works in 2025

During the winter and in the lead up to the summer of 2025, a major effort will be made to complete the whole of Drammen Station with four platforms and six tracks.  During the summer, Drammen Station will close for six weeks so we can complete all of the works. In August, a new pedestrian tunnel under the tracks will open with stairs/lifts from the platform and up to City Bridge. 

The link between the city and Jernbanekaia will be opened. At the same time, we will open the new double track from the station and through the new Drammen Tunnel. Further south, the new double track between Nykirke and Barkåker will be put into operation.

Sheeting piling, excavation and jet grouting

Information about the construction of the soil tunnel and culvert we are building is provided right below the picture.

The work involved in building the culvert and soil tunnel:

Summer 2021

We will continue our jet piling ground reinforcement work for the soil tunnel and below the construction pit for the culvert. We are dependent on foreign specialists receiving entry permits with respect to this. We comply with the government’s Covid-19 testing and quarantine requirements and do not allow guest workers onto the site before they have been tested for Covid-19 and have completed quarantine.

In the culvert, we continue to excavate between the sheet piling walls and install interior bracing to ensure the stability of the construction pit. At the end of June, we plan to cast the first section of the walls and roof of the culvert. Work on this will continue from Nedre Strøm to the start of the soil tunnel located at Konnerudgata.

We will carry out the most extensive works in the summer during the train-free period in July. This will require us to work around the clock while the line is closed in order to keep the period as short as possible. 

The noisiest works, such as sheet piling, will take place between the hours of 07:00 and 19:00. This will take place to the north of our construction site, which borders where westward bound trains enter Drammen Station. For safety reasons, this work cannot take place while trains are running. 

All of the sheet piling work must be completed before trains start to run again. During the autumn, we will also excavate this section of the construction pit so that we can cast the concrete culvert.

Otherwise, the concrete works will continue with the reinforcement and casting of the culvert. This work will continue during the summer holidays and onwards into the autumn. 

Autumn 2021 

In the autumn, we will generally continue with the same work, which consists of jet piling ground reinforcement for the soil tunnel, and excavation, bracing and casting for the culvert. In the late autumn, we will also start excavating the soil tunnel. To facilitate this, we will build ramp down into the sheet piling pit in towards Konnerudgata. From here, we will excavate the soil tunnel moving southwards under
Konnerudgata, at the same time as the uncompacted materials are secured with steel arches and shotcrete.

Future works (2022-2025):

Excavating and casting the soil tunnel and culvert will continue throughout 2022.

During the spring of 2023, the Øvre Strøm area will be restored to its original condition. Casting in the tunnel will be completed in autumn 2023, and it will be ready for the construction of the railway track. In the summer of 2025, the first trains will run through the new tunnel all the way from Drammen Station to the open air in Skoger.

Works in the next few years 

  • We will re-route Professor Smiths Allè with a temporary bridge during the summer. This will allow us to work on excavating and casting the culvert under the road.
  • Konnerudgata will be restored to its original condition during the summer.
    • Sheet piling in July at Sundland.
  • The jet piling works near the soil tunnel will continue for the following year.
  • After a while, we will start excavating the actual soil tunnel.
  • We will continue excavating, bracing and casting the culvert.

Works in 2022-2025

  • The excavation and casting of the soil tunnel and culvert will continue throughout 2022.
  • During the spring of 2023, the Øvre Strøm area will be restored to its original condition. Casting in the tunnel will be completed in autumn 2023, and it will be ready for the construction of the railway track.
  • In the summer of 2025, the first trains will run through the new tunnel all the way from Drammen Station to the open air in Skoger.

Blasting, transport and waterproofing in the Drammen Tunnel 

Information about the building of the tunnel through Strømsåsen is provided right below the picture:

Works in the summer 

Most people take their holidays in weeks 28, 29 and 30 (general holiday) and the output of those constructing the rock tunnel will be reduced during these weeks. There will be no blasting work during this period, although there will be some railway maintenance and preparation for works that will start in the autumn. Therefore, all of the laydown areas will see some activity. Most of this will take place in Gulliksrud since we will assemble two large formwork wagons that will be working inside the tunnel site. This work will start at the beginning of June and continue all summer.

Works in the autumn of 2021

After the general holiday, blasting work and transporting materials from the cross-cuts will continue at Austad and Danserud. We will start work on waterproofing in Gulliksrud and concrete mixer lorries will enter and exit the tunnel here on a regular basis.  

Works in the lead up to 2025

According to the plan, the blasting work for Danserud South will be completed in October 2021. The breakthrough between Danserud North and Austad South will take place in January 2022. This means that the blasting work for Austad southwards and Danserud northwards will be completed at the same time in January 2022. 

From Austad and northwards, the blasting work will be completed in the first quarter of 2022. This depends to some extent on the progress of the soil tunnel’s construction and where it will meet our rock tunnel. 

In 2022 and the first half of 2023, we will work on frost-proofing, waterproofing and establishing technical structures inside the tunnel. Materials will have to be replaced and we will construct the substructure for the railway track.

Work will take place in the open air in Skoger from April to October 2022.
In the summer of 2022, the culvert from Granerud will be extended and we will carry out the groundworks for linking the new line with today’s existing track.

The rock tunnel works will be completed in the summer of 2023. At that time, new professionals will join us to construct everything necessary to put the line into operation.

The tunnel will be secured with shotcrete and bolts inside between the blasting, based on a geological survey. This will make it safe to work here and run trains through here. Photo: Bane NOR

Future works

  • In all, we will be blasting 11 km of tunnel. According to our schedule, the work will be completed in the spring of 2022.
  • The tunnel will be frost and water-proofed from the spring of 2022. This will result in increased traffic to and from the construction sites.
  • At this time, materials will be transported both in and out of the tunnel site. This will continue until the summer of 2023.
  • From the summer of 2023, the focus will be on technical railway works inside the tunnel site. These will continue until the tunnel is opened in 2025.
  • You can follow the progress on the tunnel here: tunnel progress

Dear reader!

Bane NOR is constructing an important part of the InterCity project in Norway, and one of Norway’s largest railway projects. This will strengthen the rail hub in Drammen, thereby improving punctuality and increasing capacity on the Vestfold Line.

As the leader of this work, I would like to say a big thank you to all of our neighbours and passengers who are being inconvenienced due to this railway development project. I understand that at times it has been difficult for neighbours of our sites and would like to thank you for your patience and understanding of our social mission. Environmental and safety considerations are something we take very seriously in our work, and we will continue to do so from the first tunnel salvo inside the mountain until we open the new double track in 2025. Construction activities in densely populated areas such as Drammen result in various inconveniences of varying durations. Some will notice them in the form of ground vibrations, others may notice them in the form of diverted roads and new pedestrian and cycle paths.

Extensive and complicated works are well underway and will continue for several years and require many large construction vehicles. This will result in increased levels of traffic and noise – and the groundworks and blasting of tunnels will also be noticeable during some periods. We are working closely with experts from a variety of fields to facilitate safe and smooth implementation. We will always consider the environment and our neighbours in everything that we do. 

On this page you can read about our how we work, what we have to take account of when we build, and what lies ahead of us before the new double track opens in 2025. When we have completed our work, Drammen will have the opportunity to improve its urban development, which in turn will benefit all of its inhabitants. 

Hanne A. Stormo, Project Manager
