The elegant main railway station in the Hanseatic city of Lübeck is well suited to grand departures, but these are few and far between these days. The only international destination served from Lübeck is Szczecin, in Poland. Half a dozen daily trains ply a meandering route through sparsely populated terrain on a 185-mile journey that starts in Holstein and then crosses Mecklenburg to reach Pomerania. It is a region where, historically, Prussia and Sweden vied for supremacy. Today it’s a chance to see off-the-beaten-track communities in a remote part of eastern Germany.
