The Wanne-Eickel–Hamburg railway is the shortest railway link between the Metropole Ruhr and the Hamburg Metropolitan Region and hence one of the most important railway lines in northwest Germany. The Route runs over the cities Münster (Westfalen), Osnabrück and Bremen.
It was built between 1870 and 1874 by the Cologne-Minden Railway Company (CME) based in Wanne-Eickel, and branched off their main (Cologne-)Deutz–Minden route as part of the Hamburg-Venlo railway. Today it is an electrified main line which has a minimum of two tracks throughout. Parts of the route are equipped with Linienzugbeeinflussung train control which enables speeds of up to 200 km/h to be attained.
Due to its constant use by goods and passenger trains rolling along the line, day and night, it has been given the nickname Rollbahn ("Rolling Line").
History
The railway was built by the Cologne-Minden Railway Company (CME) under contract to the Prussian state as the eastern element of a line from Hamburg to Paris (Paris-Hamburg railway). The western terminus of this line was to be the town of Venlo on the Dutch railway network and it therefore went under the name of the Hamburg-Venlo railway.
In order to form a junction between this line and their existing railway network, the CME extracted a concession from the Prussian state to make Wanne station, a station which lay on the CME's main route from Cologne to Minden, the branch-off point for the line to Hamburg, in order to be able to build the line to Venlo from Haltern about 25 km to the north (see Haltern–Venlo railway).
On 1 January 1870 the first section was opened from Wanne to Münster and on 1 September of the same year its extension to Osnabrück followed. On 1 December 1872 the railway linked Harburg in the Prussian province of Hanover across the Elbe with the Hamburg Hanoverian station in Hamburg.
The section from Osnabrück to Hemelingen was completed on 15 May 1873 and it had been extended to Bremen by 16 August. The line was finally completed on 1 June 1874 with the opening of the remaining sections between Bremen and Harburg. In 1879 it was nationalised.
In Bremen the CME initially built a goods station on the site of the present-day town hall, called the Hamburg station. This was provisionally used for passenger services as well, when the old passenger station at Bremen was closed. After the new Bremen Hauptbahnhof had been completed in 1891, the line was moved there and the old station torn down. The line to Hamburg was later used again by the Bremen–Tarmstedt narrow gauge railway and is still recognisable today as the Green Train (Grünzug) park railway between Forther Straße and Innsbrucker Straße.
On 29 September 1907 the Venlo Station in Hamburg was switched from the Hanoverian station to new Hauptbahnhof which had been opened on 6 December 1906 and the halt of Oberhafen was built on the new track next to the old terminus. By 1908 the Wanne–Osnabrück section was given a second track and soon thereafter the rest of the line was also doubled.
Particularly unusual are the multi-level stations in Osnabrück (crossing with the Hanoverian Western Railway) and Dülmen (crossing with the Dortmund–Enschede railway).
Planned four-track upgrade
After the First World War the Deutsche Reichsbahn planned to upgrade the Münster–Osnabrück line to four tracks. The procurement of land was soon largely complete and work began, not least on building a second tunnel alongside the existing Lengerich (West) Tunnel. The old tunnel was to continue to be used.
The world economic crisis at the start of the 1930s weakened the country and brought the project to a standstill. Because the new Lengerich tunnel was ready and had a better line it was connected to the existing route and taken into service. The old Lengerich tunnel remained out of commission until the Second World War when it was put to use for a while as an underground arms factory. After the war it was returned to civilian use; at one stage being employed as a rifle range for an arms dealer.
Signs of the four-track upgrade can still be seen from immediately north of the tunnel to the area of Hasbergen in the shape of widened embankments and track overbridges. Here the expansion of the line was relatively well advanced.
Upgrade in the 20th century
In the 1960s the line was electrified.
In 1983 the Hamburg S-Bahn opened its own line between the stations of Hamburg-Harburg and Hamburg Hbf (for routes S3 and S31), that ran between the South and North Elbe parallel to the high-speed line. Its halts at Hamburg-Wilhelmsburg and Hamburg-Veddel were closed as a result.
