"From the summer of 2028, a new direct train connection between Oslo, Copenhagen, Hamburg and Berlin will begin. The route is established in cooperation between Norwegian train operator Vy, DSB and Deutsche Bahn.
For the first time in more than 20 years Denmark and Norway will get a direct train connection."

Also Talgo control cabs have been approved (for control?) in Denmark but not in Germany.
