Electrification Programme

Banedanmark electrifies parts of the Danish rail network

Why Electrification?

Banedanmark has launched a large-scale project for the electrification the majority of the Danish state railway network

With the Electrification Programme, Banedanmark is electrifying the majority of the Danish state railway network. 820 km of the state railway will be electrified (in total approximately 1362 km, since most of the sections have double tracks). The Danish Parliament has allocated up to 12 billion DKK to the Electrification Programme.

Today, 1756 km of railway is already electrified: the main section on the Danish railway network between Øresund and Padborg via Storebælt and Lillebælt, as well as the sections Tinglev-Sønderborg and København-Helsingør.

The first big milestone for the Electrification Programme was reached with the electrification of section 1, consisting of 57 km between Esbjerg and Lunderskov. The handover of the section took place in April 2017 and from the 7th of August 2017 DSB has been driving passenger electric trains on the section.


The Electrification Programme includes the following sections:


  • Esbjerg-Lunderskov

In progress

  • København-Ringsted

  • Køge Nord-Næstved

Upcoming sections

  • Ringsted-Holeby

  • Roskilde-Kalundborg

  • Fredericia-Aarhus

  • Aarhus-Aalborg

  • Vejle-Struer

  • Aalborg-Frederikshavn


A high-voltage network provides power to the electric trains. The power is transmitted through cables to a transformer station where it is transformed from 150 kv to the 25 kv that the electric trains use. The power is led to the trains via overhead contact wires hanging from 9-meter-tall masts, which are placed at intervals of up to 100 meters.

Apart from the electrification itself, the project also includes; reconstruction of bridges to make room for overhead contact wires underneath, immunisation of other installations towards electrification, clearing of vegetation along the railway etc.

We are currently working on the following sections:

The first big milestone of the Electrification Programme has been reached. The 57 km between Esbjerg and Lunderskov is the first section to be electrified in many years, and with the electrification of this section, the first step has been taken towards electrifying the majority of the state railway network.

The handover of the section took place on April 21st 2017. Power is on, the catenary system is operative and from the 7th of August 2017 DSB has been driving passenger electric trains on the section. With the electrification of this section, it is now possible to drive electric trains all the way from Copenhagen to Esbjerg.

Since 2014, Banedanmark has been in the process of removing vegetation along the line and reconstructing bridges to make room for the new electrical power supply system, which is installed along the entire stretch. At the same time, transformer stations have been built in Andst and Esbjerg, as well as two smaller auto-transformers in Esbjerg and Holsted, which will provide the power to the line.

In the period of 2010-2019, Banedanmark is constructing a new double-tracked high speed railway between København and Ringsted via Køge. The line is built for a speed of up to 250 km/h for passenger trains and is the first railway in Denmark that can operate high speed trains.

The construction of tracks on the new section is finished and Banedanmark is currently in the next phase of the project – electrification. The electrification of the 60 km between København and Ringsted was commenced in April 2017 and is planned to be completed summer 2018.

Foundations are currently being installed with approximately 100 meters in between. When all the field work on the section has been completed, the line will be test-driven, before it is expected to open in 2019.

The preparatory work to electrifying the 45 km between Køge Nord and Næstved started in the spring 2015. The driving speed on the section was upgraded from 120 km/h to 160 km/h. This, together with the fact that the line will be connected with København-Ringsted in Køge Nord instead of going through Roskilde as it does today, will safe passengers up to 10 minutes of travel time between Næstved and Køge. Moreover, almost all bridges have been replaced with new ones, which are tall enough for the new electrical power supply system.

In 2016, expropriations were carried out as well as the removal of vegetation along the line. Cutting and trimming of expropriated trees at private landowners will be taking place during 2017 and is finalized in the Spring 2018. Finally, in 2018, the actual electrification of the section will be initiated and the section is expected to be finalized by the end of 2018.
