At the same, the Prussian Eastern Railway was planned from Berlin to Königsberg (present day Kaliningrad), passing through stations like Küstrin (Kostrzyn nad Odrą), Schneidemühl (Piła), Bromberg (Bydgoszcz) with a branch to Danzig (Gdańsk). The station of Kreuz (Krzyż) at the crossing point of Stettin–Poznań and Berlin–Königsberg had primarily been laid out for the latter to line be the trunk. Most parts of this main line were opened in 1852, but the construction of the bridges across Oder river at Küstrin (Kostrzyn) and Vistula and Nogat rivers between Dirschau (Tczew) and Marienburg (Malbork) was not completed before 1857.
