​Electrifying the Danish rail network will secure shorter travel times and greener transport.

Over the next decade, COWI and its French cooperation partner Systra will work on electrifying the Danish rail network.

The project will result in shorter travel times for passengers as trains will be able to run at higher speeds, as well as in greener transport thanks to the switch from diesel-powered to electric trains.

The project

Together with Systra, COWI will prepare the tender documents for the design-build contract, which will cover electrification, establishment of traction current and power supply systems, negotiation and contracting, as well as subsequent review and approval of the contractor's design and supervision of the works.

The project is one of the largest, most complex rail projects on Danish soil. To begin with, the political decision to electrify the network covers nine sections.

According to plan, the electrification of the Danish rail network will run until 2026.

First nine sections

The first nine sections to be electrified are:

  • Esbjerg-Lunderskov (114 km)
  • Copenhagen-Ringsted (120 km)
  • Køge N-Næstved (45 km) 
  • Ringsted-Holeby (258 km)
  • Fredericia-Aarhus (218 km)
  • Aarhus-Aalborg (280 km )
  • Roskilde-Kalundborg (112 km)
  • Aalborg-Frederikshavn (85 km)
  • Vejle-Struer (130 km)


The sections total 1,362 km, and the first section from Esbjerg to Lunderskov is to be completed in 2016.

The necessary experience

Teaming up with its French partner Systra, COWI has the experience and knowledge that are necessary to solve a project of this complexity. For instance, Systra has experience with French high-speed trains. The maximum operating speed in Denmark will be 200 km/h.

Greener transport in Denmark

The electrification is part of an agreement on a green transport policy, one of the objectives being to render the rail network independent of fossil fuels in the long term. Thereby, this project constitutes a large step towards greener transport in Denmark.
