It is generally agreed that electrical traction powered operation of heavily trafficked rail sections is the most financially viable method of operating trains. Electrical operation is environmentally sustainable and provides passenger traffic as well as freight traffic with a range of benefits; most notably the possibility of using higher traction power and therefore reduced travel times.

Ramboll has extensive expertise within all areas of railway, metro and light rail systems, including overhead catenary systems, interlocking systems and power supply.

Over the years Ramboll has assisted in the project design of many new railway sections with electrical operations, renovation, and modernisation of existing facilities. We also deliver consultancy services on optimisation of maintenance, and our expertise within this field has become widely recognized. Furthermore, Ramboll offer consultancy services in relation to system integration between the electrification systems with optimisation of budgets and related investments.

Ramboll has developed a range of database tools to be used in the project design of overhead catenary systems. This includes development of 3D project design tools to automate the drafting of plans, cross sections and elevations. This allows a highly efficient and cost effective design of catenary systems.

Our competencies within electrification include:

  • Proposals regarding electrification strategies including budget analysis and investment analysis
  • Evaluation of existing systems
  • Technical and financial proposals regarding electrification of new sections or modernisation of existing facilities
  • Project design of the whole project cycle from inception to post completion evaluation
  • Requirement specification and design of tender documents and contract strategies
  • Test and analysis of dynamic circumstances
  • Planning and preparation of potential equalizations 
  • Preparation of maintenance strategies
  • Implementation of system approvals
  • Construction management and technical inspection


Train station

Extension of Copenhagen metropolitan railway section

The Project concerns central parts of the Copenhagen Suburban Mass Transit lines between Copenhagen Central Station and Valby. In connection with the construction of the Køge Bugt line, the northbound track (5th main track) was lead all the way to the platform on Copenhagen Central Station, while the corresponding southbound track (6th main track) was not established.

Ramboll’s consultancy services regarding the existing metro lines encompassed all railway infrastructure disciplines. For Cityringen, in joint venture with Atkins, we are also responsible for rolling stock (the train fleet) and a large automated train depot which houses maintenance facilities and the control centre for the entire line.

The Copenhagen Metro

It was a groundbreaking event when the Copenhagen Metro opened its first fully automated, driverless metro in 2002. Since then, it has become the most natural thing in the world for the citizens of Copenhagen to travel at speeds of 80km/h 18 metres below street level.

Light rail

Light rail as enabler for urban development

The future light rail connection along the ring road ‘Ring 3’ just west of Copenhagen not only promotes a more coherent city infrastructure. It also has the potential to become a powerful enabler for urban growth and development.
