U12 (Berlin U-Bahn)


The U12 is a former Berlin U-Bahn line. It existed between 1993 and June 2003, as a peak-time and night line between Ruhleben and Warschauer Straße stations.
The line was withdrawn in June 2003 and more night-time lines were introduced, which is U1, U2, U3, U5, U6, U7, U8 and U9.
On 22 June 2020, the U12 line was reinstated due to maintenance repairs of the U1, U2 and U3. The U12 runs between Kottbusser Tor to Ruhleben station. It is expected to run until 9 August 2020

Route

From November 1956, no trains continued to run continuously from Pankow to Ruhleben, as the line AI shortened to today's Theodor-Heuss-Platz and a new ABI designated line was installed, which was already in May 1957 line BI called. This changed from Ruhleben coming behind the subway station Wittenbergplatz on the relief route direction Warschauer Brücke.
In 1966, this became the well-known line 1, after which the eponymous musical is named and whose plot plays on this line, before renumbering to U1 in 1984. In 1990, a night-time variant was introduced.
Their eastern end point was from 13 August 1961 to 13 November 1993 due to the route separation by the construction of the Wall of the subway station Schlesisches Tor in West Berlin district Kreuzberg. After German reunification, the connection between the stations Warschauer Straße and Schlesisches Tor was reopened in October 1995. This led to the lines U1, U12 and U15 to the Warschauer Straße.

Special

On 18 August 2006, this line was in service again as a replacement service for the U2 between Gleisdreieck and Ruhleben. Bridge building works between Gleisdreieck and Bülowstraße prevented trains running on that track until 18 March 2007. The trains that were used are A3E, A3L67/71/82/92, GI/1, GI/1E and HK.
In 2011 line U12 was brought back into existence again due to repair work currently being undertaken at Gleisdreieck, however it was only after protests by passengers who had to transfer at Wittenbergplatz to continue their journeys on lines U1 and U2 that line U12 was re-established for the second time.
It resumed its old route for a short period of time between May and November 2015, due to repair work taking place in the Gleisdreieck station.
On 22 June 2020, the U12 line was reinstated due to maintenance repairs of the U1, U2 and U3. The U12 runs between Kottbusser Tor to Ruhleben station. It is expected to run until 9 August 2020.
