Unique offer in high-speed rail

At AFRY, we have worked in large railway projects for decades, we are deeply involved in the development of Europe's railway system and we have worked with high-speed rail (HSR) projects in several European countries.

Our offer in high-speed rail is unique. We combine a strong local presence with international experts. We know the local laws, rules, regulations, what the geographical conditions are and who the client is. Our network of experts and their experience is global. Their willingness to learn from each other, to share their insights, is essential for our clients success. Our experts are at the forefront of high-speed rail development and support the project with the latest best practice.

With AFRY, you get the best of both worlds, our local knowledge and presence in combination with international experts and their experiences.

In defining our high-speed rail offer, we have chosen to adhere to the Directive 2004/50/EC (amending Directive 96/48/EC)- Interoperability of the trans-European high speed rail system where there are three catorgories of high-speed lines identified. The first are specially built high-speed lines equipped for speeds generally equal to or greater than 250 km/h. The second are specially upgraded high-speed lines equipped for speeds of the order of 200 km/h, and the third category are specially upgraded high-speed lines which have special features as a result of topographical, relief or town-planning constraints, on which the speed must be adapted to each case.

At AFRY we have experience of working in all three categories.

East Link, Stockholm- Linköping, Sweden

AFRY is involved in the planning of the East Link, which will enable people and goods to travel faster through eastern Sweden by train. The East Link, which is currently under construction, will be a new double track high speed railway line, linking the greater Stockholm area to Linköping. The trains will be able to run at speeds of around 250 km per hour and carry passengers from Stockholm to Linköping in one hour. AFRY has teamed up with Tyréns in the development of the stretch between the municipalities of Södertälje and Trosa, which includes production of railway plans with environmental impact assessments, basic design and design programmes.

Espoo-Salo -railway, Finland

The One Hour Train is a high-speed-rail link between Turku and Helsinki, Finland. Espoo-Salo-railway project is divided in three parts and AFRY in charge of a part between two cities, Lohja and Suomusjärvi. In addition to leading the project AFRY is liable to the geotechnic design, railway engineering, tunneling and bridge engineering. Varying topography sets challenges to engineering when the height of the railway and placing the tunnels will be optimized by the costs and environment.

World’s longest railway tunnel, Gotthard Base Tunnel, Switzerland

AFRY has helped link southern and northern Europe through the Swiss Alps via the Gotthard Base Tunnel – the longest railway tunnel in the world. With its 57 km, the Gotthard base tunnel is the longest railway tunnel in the world, and the core of the new transalpine railway axis AlpTransit. The twin single track high speed rail tunnels run between Erstfeld and Bodio in Switzerland. In connection with its planning and construction, AFRY provided environmental services, tunnelling, electromechanics, rail traffic and ventilation/safety. The project included the construction of a 800 m vertical shaft and a 2 700 m inclined gallery, plus multifunction stations where adits meet the base tunnel. Certain stretches were particularly demanding, with soft rock under high pressure.

World's longest immersed road and rail tunnel, The Fehrmarn Belt tunnel, Denmark

The Fehmarn Belt tunnel will link Denmark to the continent. With its 18 kilometres, the Fehmarn Belt tunnel will be world's longest immersed tunnel for both road and rail. When finished, it will shorten the trip from Copenhagen to Hamburg by 160 km. AFRY and sub-consultants contribute to the tunnel on several levels:

Design of mechanical and electrical systems for communication, HVAC, fire, drainage, power supply, data network, lighting, access control, PA, CCTV, weather surveillance, traffic detection, emergency stations, tolling and ITS. In-house consultancy services for review and provision of in-house resources related to construction management, excluding railway systems and safety.

The longest railway tunnel in the Nordic countries, Follo Line, Norway

The Follo Line is Norway's largest transport project and Nordic region's longest railway tunnel of 19.5 km by far. The Follo Line will give passengers an upgraded and faster public transport route between Skiing Centre and Oslo.

Selecting the right consultant

The skills and experiences needed to carry out a high-speed rail project are many. Some are unique to the challenges of speed, others relate to the environmental impact, and even more are similar to those encountered when building railways in general. These are some of the competencies and skills that consultants require – at AFRY we have them all.
