It was trains from Hamburg to Copenhagen used to run on the Fehmarn Ferry until the line was shut for reconstruction, they now run via Padborg.

The Snalltaget sleeper train from Berlin to Malmo used to run on the ferry from Sassnitz to Trelleborg avoiding Denmark altogether, that stopped because the ferries don't run on that route any more, and the train also runs via Padborg.
