the line each day, including a fast passenger trains and a stopping train between Hamburg and Stettin, and a train ran between Hamburg and Neubrandenburg. At the boundary in Strasburg, trains continued after a brief stop. After World War I, the Friedrich-Franz Railway and the Prussian State Railways were taken over by the German State Railways. Strasburg was on the border of lines controlled by railway divisions in Schwerin and Stettin. Services changed little following nationalisation. A continuous D-express and an ordinary express ran to Hamburg, and four pairs of ordinary trains ran to Stettin (and five between Bützow and Güstrow), with one of them also running all the way from Hamburg to Stettin. There were additional trains on parts of the route. Between Pasewalk and Szczecin service levels were much denser. Briefly trains stopped in Remplin (only for two excursion trains on Sundays) and Nienhagen (introduced in early 1940s). After the Second World War both stations disappeared from the train schedules. 1945–1990 After the Second World War most of the route was in East Germany and became part of the East German railways. The section from the border at Grambow to Szczecin became part of Polish State Railways (PKP). The former continuous line between Hamburg and Szczecin was disrupted by the border with Poland and the Inner German border. The second track, which existed west of Teterow, was dismantled after the war, making it a single-track line, as it still is. Because of the dismantling of the Lloyd Railway between Neustrelitz and Plaaz for reparations to the Soviet Union trains between Berlin and Rostock ran from 1945 to 1961 via Güstrow and Neubrandenburg. In the first years after the war, there was little travel to Poland. Between 1950 and 1952 there was a continuous through coach connection between Berlin and Szczecin via Pasewalk. After that the route across the border was for a long time only used for freight. Passenger services were only resumed in May 1972, following the introduction of visa-free travel between East Germany and Poland. Since 1990 In 1991, passenger services to Poland were resumed. As a result, three to four pairs of trains ran to Szczecin, the rest ended in Grambow. In 2001 services to Szczecin were increased to a frequency of every two hours. Services have gradually increased on the Bützow–Pasewalk section. In 1995 Regional-Express trains (stopping in Güstrow, Teterow, Malchin, Stavenhagen, Neubrandenburg and
