I think there's still a route between Germany and Denmark that does this


There is. Between Puttgarten and Roedby on the Hamburg to Copenhagen route.
You can stay on the train, or can go into the ship.

Also there's an overnight Malmo (swe) to Berlin (de) service that travels on
the ferry between Malmo and Sassnitz.

Didn't get much sleep that night. The coaches used to be Deutsche Reichsbahn
couchettes, which seemingly hadn't changed much since the days of the Iron
Curtain, plus the rail deck was in the bowels of the ship. not far from the
engine room.
