Early works have started for a project to upgrade 115km of railway linking the Danish town of Ringsted to the planned Fehmarnbelt crossing.
Danish railway infrastructure manager Banedanmark announced that preparatory construction had begun for the scheme to upgrade the cross-island line.
Currently partially single track, the line allows trains to run at 120km/h on Lolland-Falster and 160km/h on Zealand.
The project will see it upgraded to a double-track electrified line with three overtaking places and top speeds of 200km/h.
This will allow the line to link to the 19km Fehmarnbelt immersed tunnel road and rail link, between Germany and Denmark.
Danish minister for transport Magnus Heunicke said: “The Ringsted-Fehmarn line will allow for more trains, better and timelier train traffic and significantly shorter travel times.
“The Ringsted-Fehmarn line will not only strengthen the Danish regional infrastructure, but it will also link Scandinavia much better with Central Europe.
“At the same time, international freight traffic will be improved when the journey between Sweden/Eastern Denmark and Germany is 160km shorter through the tunnel under the Fehmarn Belt.”
