It connects the new Berlin Hauptbahnhof, or main railway station, to an interchange with the S-Bahn at Brandenburger Tor. Currently, it has only three stations, does not connect to any other U-Bahn line, and is operated as a shuttle line using a single train. The line is the newest U-Bahn line, and was constructed as part of an extension of the U5 that was subsequently postponed due to financial difficulties. As much of the work on this disconnected section of the extension had been completed, it was decided to complete the section and open it as a separate line in 2009. In 2010, construction began on the intervening section connecting Brandenburger Tor to Alexanderplatz; on 4 June 2018 U55 was closed temporarily to accommodate the work needed to connect it to this new phase of the project. The three-station U55 is scheduled to reopen on 11 December 2018; the complete project, merging U55 and U5 into a single line, is scheduled to open in 2020.[2] HistoryOriginsThe unusual nature of U55 reflects Berlin's troubled finances. When the German government decided to move from Bonn to Berlin under the Chancellor of West Germany Helmut Kohl, who also announced the reunification of Germany on 3 October 1990, it was decided to refurbish the area around the Bundestag into a modern government complex. As part of this effort, there were plans to extend the U5 from its current western terminus at Alexanderplatz through the city centre, past the Brandenburg Gate and the Bundestag, to the new central train station, Berlin Hauptbahnhof. This Kanzlerlinie (Chancellor Line), so nicknamed because it passed through the government quarter, was originally planned since the 200km plan as a diagonal line through central Berlin, continuing to Turmstraße in Moabit, where it would link with the U9, and on to Jungfernheide, where it would connect with the S-Bahn ring and U7. The line was also planned to go via Tegel Airport (to be replaced by Urban Tech Republic), Scharnweberstraße towards Rathaus Reinckendorf. As this was a long-planned route, short tunnels exist at both Jungfernheide and Turmstraße to accommodate the new line. Plans were discarded as tram was also planned to be extended west. For now, the line is only approved to terminate at the Hauptbahnhof, with the route to Jungfernheide and beyond to be built later. ConstructionIn 19 January 2000, construction began on the western end of this extension. However, around that time the city council suffered a major financial crisis. However, the city had accepted money from the German federal government for the construction work already finished, and by the terms of the agreement, the city would have had to return the money if there were no operating trains on the line. In 2004, the city and federal governments reached a compromise: the city would complete the short section of line that was largely complete between Berlin Hauptbahnhof and Unter den Linden S-Bahn station (renamed "Brandenburger Tor" in 2009) and run it as a single-track shuttle with a single train, without any signaling. Although transit planners projected that such a shuttle would not attract a significant ridership, the city determined that the cost of building and operating the line would be less than the cost of returning the money to the federal government. OpeningThe opening of the line between Berlin Hauptbahnhof and Brandenburger Tor was delayed owing to extreme groundwater problems at the site of the latter new station. It was finally opened on 8 August 2009.[3] OperationStations
With the opening of the U-Bahn station, the existing Unter den Linden S-Bahn station was renamed Brandenburger Tor (for the nearby Brandenburg Gate). The title "Unter den Linden" has been given to a station (under construction) further east at the junction with Friedrichstraße, where the U5 will intersect the U6. The train runs every 10 minutes and, due to the low demand, there is no night service. Rolling stockBecause the U55 is not physically connected to the rest of the U-Bahn system, any trains being delivered to the new line need to be taken by low loaders on the street and set on track through a tunnel opening located north of Hauptbahnhof station. There is also a provisional workshop for basic maintenance and cleaning of carriages. Formerly, trains that were running on U55 were F79 trains. However, there were not enough trains on the Berlin U-Bahn larger profile lines, so the two U55 trains were being taken off from the service and placed on U6 in April 2017. In return, the older D class trains were modernized, and was from the museum{{clarify|date=March 2018}}, existing units will be used in the meantime until the U5 extension opens in 2019. Linking U55 and U5The designation of the line as U55 indicates that it is ultimately intended to become part of the U5 line. Construction of the link to enable this commenced in April 2010 was originally expected to be completed by 2017. Construction works suffered from continued difficulties, mainly concerning high water contents in the soil; in November 2015 the opening date was postponed to 2020.[4] The link will be {{convert|2.2|km}} in length, and connect the Brandenburger Tor terminus of the current U55 to the Alexanderplatz terminus of the current U5. Along its route it will serve new U-Bahn stations at Berliner Rathaus, Museumsinsel and Unter den Linden, with the last providing an interchange with line U6.[5][6] This new interchange station will replace the current U6 station at Französische Straße, located a little further to the south on Friedrichstraße, which will then be closed.
