Expansion of the railway at Kalvebod begins now

On 21 June 2026, Sund & Bælt will begin establishing passing loops at Kalvebod between Ellebjergvej and Bådhavnsgade. The project will increase capacity on the railway around Copenhagen and create more space on one of Denmark’s busiest routes.

The passing loops are part of Infrastructure Plan 2035 and will strengthen the connection from Roskilde via København Syd to Copenhagen Airport. They will also help manage the expected increase in rail traffic when the Fehmarnbelt Link opens.
“The new passing loop at Kalvebod is necessary if we are to avoid bottlenecks for rail traffic in the future. The tracks are already heavily used today by both freight and passenger trains, and in the long term increased capacity will enable better utilisation and flexibility on the tracks and relieve traffic at Copenhagen Central Station,” says Klaus Jørgensen, Project Director at Sund & Bælt.
The existing railway corridor across Amager is today a key connection for both Danish and international traffic. With the new tracks, it will be increasingly possible to separate fast passenger trains from slower freight trains and thus optimise the use of the railway. The project forms part of the Trans-European Transport Network (TEN-T) with co-financing from the EU.
The work begins with the establishment of construction sites as well as earthworks and preparatory works along the section between Bådhavnsgade/Fragtvej and Ellebjergvej.
The construction work is expected to be completed by 2028.
