Danish rail infrastructure company Banedanmark has opened the high-speed railway line between Copenhagen and Ringsted.

The line, named Ringstedbanen (the Ringsted Line), was inaugurated by Danish Crown Prince Frederik.

According to digital news publisher The Local dk, the line connects the two cities via a station at Køge North. A major section of the line runs alongside the motorway network.

The line is capable of supporting high-speed operations with trains travelling up to 250km/h.

Initially, railway operator DSB will run existing conventional trains on the route at higher speeds, with faster trains to be introduced in future.

A new timetable is set to be introduced in December, following which the trains will start operating on the line at higher speeds, reducing the journey time between the two cities.

Banedanmark director Per Jacobsen said: “This will make the railway to and from Copenhagen more efficient and robust. The new track will help us improve the timetable, increase departures and reduce delays.”

Currently, the speed limit on the Danish railway network is 180km/h.

Construction work on the Ringsted Line began in 2012 as part of the plan to improve railway connectivity between Copenhagen and Ringsted.

The overall project is estimated to have cost $1.83bn.

Last month, the European Investment Bank (EIB) sanctioned a €200m loan to improve the Danish rail network connection to the Fehmarnbelt link.

The Fehmarnbelt link is an under-construction road and rail undersea tunnel connecting Germany and Denmark.

The $7.88bn undersea tunnel project is scheduled to be completed in 2028.
