Seems now part of my wish come true here. Made this post some time ago. Just hope they would/will make it before 1989 when it was East Germany when they had to pick freight from the harbour in Sassnitz. Sassnitz-mukran-stralsund-rostock-berlin! I would had liked this route from Germany! Thread by: pantherz, Jan 31, 2019
There is a DDR Rügenbahn freeware project in the making, including the freight harbour. There is a thread about it in www.rail-sim.de The route builders are serious and are the men behind several Danish routes.
