Vogelfluglinie

The Vogelfluglinie (German) or Fugleflugtslinjen (Danish) is a transport corridor between Copenhagen, Denmark, and Hamburg, Germany.

Construction was started on the Danish side in 1941 after the Nazi occupation force pushed the matter, but work was halted again in 1946.

Danish-German negotiations on 29 June 2007 culminated in an agreement to complete the link by 2028, essentially on the basis of Danish funding.

With the completion of the Great Belt Bridge freight trains are no longer directed via Rødby-Puttgarden, but via Funen and Jutland.
