The Berlin Northern Railway () is a 223-kilometre-long main line route, that runs from Berlin via Neustrelitz and Neubrandenburg to Stralsund on the Baltic Sea coast. Nowadays, long-distance and regional traffic on the Nordbahn is routed at Hohen Neuendorf onto the Berlin Outer Ring to the Karower Kreuz and on to Berlin Main Station or Berlin-Lichtenberg. History Construction of the line was preceded by decades of planning from 1843 until 1870 when the newly founded Berlin Northern Railway Company (German: Berliner Nord-Eisenbahn-Gesellschaft) gained the concessions from the states of Prussia and Mecklenburg-Strelitz. For financial reasons, the company was dissolved on 15 December 1875. The Prussian government acquired the unfinished railway and handed over further construction of it to the Lower Silesian-Markish Railway (Niederschlesisch-Märkische Eisenbahn). The opening took place in three stages: 10 July 1877: Berlin–Oranienburg–Neustrelitz–Neubrandenburg (134 km) 1 December 1877: Neubrandenburg–Demmin (42 km) 1 January 1878: Demmin–Stralsund (47 km) The construction of the Northern Railway had a significant impact on the villages to the north of Berlin that were in the catchment area of the railway line. In some cases their population multiplied in the following decades. The term Nordbahn became part of place-names (for instance, Glienicke/Nordbahn) and newspapers used its name (Nordbahn-Nachrichten). The Berlin terminus of the railway, but only for freight, was the first freight yard at Eberswalder Straße, now the site of Mauerpark. Passenger services began at the original Nordbahnhof (North Station) in Pankow, today's Wollankstraße station, still evident in the design of the station and its forecourt. At the end of the 19th century the terminus of the railway or passenger trains for Berlin regional services was relocated to the Stettiner Bahnhof (Stettin—now Szczecin—station), built on Invalidenstraße; the freight remained at Eberswalder Straße. Up to 1912 separate suburban tracks were built next to the long distance tracks between Gesundbrunnen and Frohnau. At the same time the line was moved to an embankment, to eliminate level crossings. In 1926, the section from Frohnau to Borgsdorf was treated similarly. In 1925 the suburban services were electrified on the DC system on the section from Gesundbrunnen to Oranienburg. The route later became part of the Berlin S-Bahn. In 1950 the Stettiner Bahnhof was renamed the Nordbahnhof. Electrical operations continued until the building of the Berlin Wall on 13 August 1961, when the line between Frohnau and Hohen Neuendorf was closed. The Berlin section of the Northern Railway had already
