CERTIFER as Notified Body is involved in the Danish Electrification Program (EP) i.e. the electrification of several railway sections like Esbjerg – Lunderskov, Køge Nord – Næstved, Copenhagen – Ringsted, and Fredericia – Aarhus. The aim of the EP is to allow the electric trains operating on most of the Danish railway network. The system that will be provided should be a well-proven system already approved under the TSI with some minor modifications to fit in the Danish infrastructure. The electrification system is formed by a Catenary system, a Power Supply system and an Electrical Remote Center.
