BVG Class D
Class D was a type of electric multiple unit An electric multiple unit or EMU is a multiple-unit train consisting of self-propelled carriages using electricity as the motive power. An EMU requires no separate locomotive, as electric traction motors are incorporated within one or a numbe ... train used by the Berlin U-Bahn. After World War II the trains of the Berlin U-Bahn were worn out, making a new series of trains necessary. From 1957 on the new ''D'' type trains were delivered (also called Stahldora/Steel Dora). They were made of steel, making them very heavy. In 1965, the ''DL'' type was developed, which was constructed from lighter metals (also called Dora). This way, weight was reduced by 26%. Like in earlier types the seats were located along the sides of the train. Class D The D type cars have been introduced in various phases: *D 55: The test vehicle (2000/2001), which is on the Line C II (Mehringdamm - Tempelhof) *D 57: 26 trains (2002/2003 - 2052/2053), whic ...

Orenstein & Koppel
Orenstein & Koppel (normally abbreviated to "O&K") was a major Germany, German engineering company specialising in railway vehicles, escalators, and heavy equipment. It was founded on April 1, 1876 in Berlin by Benno Orenstein and Arthur Koppel. Originally a general engineering company, O&K soon started to specialise in the manufacture of railway vehicles. The company also manufactured heavy equipment and escalators. O&K pulled out of the railway business in 1981. Its escalator-manufacturing division was spun off to the company's majority shareholder at the time, Krupp, Friedrich Krupp AG Hoesch-Krupp, in 1996, leaving the company to focus primarily on construction machines. The construction-equipment business was sold to New Holland Construction, at the time part of the Fiat Group, in 1999.

2004 Disestablishments In Germany
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

Electric Multiple Units Of Germany
Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of an electric charge, which can be either positive or negative, produces an electric field. The movement of electric charges is an electric current and produces a magnetic field. When a charge is placed in a location with a non-zero electric field, a force will act on it. The magnitude of this force is given by Coulomb's law. If the charge moves, the electric field would be doing work on the electric charge. Thus we can speak of electric potential at a certain point in space, which is equal to the work done by an external agent in carrying a unit of positiv ...

U5 (Berlin U-Bahn)
U5 is a line on the Berlin U-Bahn. It runs from Hauptbahnhof in Mitte eastwards through Alexanderplatz, Friedrichshain, Lichtenberg and Friedrichsfelde, surfaces in to pass Kaulsdorf and Hellersdorf above ground and finally reaches city limits at Hönow. Route Line U5 connects Moabit with the large housing estate of Hellersdorf and the Brandenburg town of Hönow, but ends just outside the eastern city limits of Berlin. It begins at Berlin Hauptbahnhof (central station) and heads southeast under the Spree river, the Spreebogenpark and the Platz der Republik to Brandenburg Gate. From there it follows Unter den Linden, crossing line 6 at Friedrichstraße. After Museumsinsel station, the line runs under Rathausstraße, passing under the Humboldt Forum. After leaving Alexanderplatz, it takes a sharp right turn under Karl-Marx-Allee.

U55 (Berlin U-Bahn)
U55 was an U-Bahn line in the German capital city of Berlin. It connected the new Berlin Hauptbahnhof, or main railway station, to an interchange with the S-Bahn at Brandenburger Tor. It had only three stations, did not connect to any other U-Bahn line, and was operated as a shuttle line using a single train. The line 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 until December 2018 to accommodate the work needed to connect it to this new phase of the project. The complete project, merging U55 and U5 into a single line, opened on 4 December 2020. Operation of the U55 ceased on 17 March 2020 in preparation for the line's ...

Berlin Wall
The Berlin Wall (german: Berliner Mauer, ) was a guarded concrete barrier that encircled West Berlin from 1961 to 1989, separating it from East Berlin and East Germany (GDR). Construction of the Berlin Wall was commenced by the government of the GDR on 13 August 1961. It included guard towers placed along large concrete walls, accompanied by a wide area (later known as the "death strip") that contained anti-vehicle trenches, beds of nails and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the "will of the people" from building a socialist state in the GDR. The authorities officially referred to the Berlin Wall as the ''Anti-Fascist Protection Rampart'' (german: Antifaschistischer Schutzwall, ). The West Berlin city government sometimes referred to it as the "Wall of Shame", a term coined by mayor Willy Brandt in reference to the Wall's restriction on freedom of movement.
