Bornholm Tunnel Bornholm Tunnel The Bornholm Tunnel (, ) is a proposed railway tunnel which would be built between the island of Bornholm, belonging to Denmark, and Scania in Sweden. The tunnel would provide a fixed link to the island, both using direct trains running from Copenhagen and with a motorail service to transport automobiles. The tunnel would be long and provide a one-hour transit time for cars, including loading and unloading, and a two-hour service by rail to Copenhagen via the Ystad Line and the Oresund Line. The latter could be further reduced with construction of high-speed rail in southern Scania.
Bornholm Cable Bornholm Cable Bornholm Cable is one of the longest submarine three phase AC cables in the world. It is a 60 kV cable interconnecting the power grids of Bornholm and Sweden. The Bornholm Cable starts at 60 kV substation Hasle () and runs on its 1.4 kilometres as underground cable with a cross section of 400 square millimetres to the Baltic Sea, where the 43.5 kilometres long submarine cable section starts. At this section copper conductors with 240 square millimetres are used. From the landing point at Sweden it runs on a length of 700 metres as underground cable with
