ELECTRIFICATION OF THE DANISH RAILWAY
With the Electrification Programme, Banedanmark is electrifying the majority of the Danish state railway network in the period between 2014 and 2027. Up until year 2027, 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 Electrification Programme includes the following sections:
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 7-meter-tall masts, which are placed at intervals of 15-60 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.
Electrifying the majority of the state railway network helps setting the framework for a more modern railway with cheaper and more stable train service at the same time as electrical power-driven trains are for the benefit of the environment. Thus, electrification contributes to ensuring a reliable and attractive railway benefiting passengers, operators as well as the environment.
Electrification allows for:
- Shorter travel time – electric trains can drive at a higher speed (160-250 km/h), and they accelerate and brakes faster
- Less noise when the trains leave the platforms
- Cheaper and more stable train service
- Lower costs of operation and maintenance
- Electric trains have environmental benefits - reduction of CO2 emissions and particle pollution
