Passage: On 13 June 1990, the East German military officially began dismantling the Wall, beginning in Bernauer Straße and around the Mitte district. From there, demolition continued through Prenzlauer Berg/Gesundbrunnen, Helligensee and throughout the city of Berlin until that December 1990. According to estimates by the border troops, a total of around 1.7 million tonnes of building rubble was produced by the demolition. Unofficially, the demolition of the Bornholmer Straße began because of construction work on the railway. This involved a total of 300 GDR border guards and - after 3 October 1990 - 600 Pioneers of the Bundeswehr. These were equipped with 175 trucks, 65 cranes, 55 excavators and 13 bulldozers. Virtually every road that was severed by the Berlin Wall, every road that once linked from West Berlin to East Berlin, was reconstructed and reopened by 1 August 1990. In Berlin alone, 184 km of wall, 154 km border fence, 144 km signal systems and 87 km barrier ditches were removed. What remained were six sections that were to be preserved as a memorial. Various military units dismantled the Berlin/Brandenberg border wall, completing the job in November 1991. Painted wall segments with artistically valuable motifs were put up for auction in 1990 in Berlin and Monte Carlo.
Did more border guards or Pioneers of the Bundeswehr work on construction? How many different components (including ditches and signal systems) were removed in Berlin alone? How many months after East Germany began dismantling the Wall were the roads that once linked West Berlin to East Berlin reopened? How many months after the  East German military officially began dismantling the Wall did the dismantling last for? How many months after the East German military officially began dismantling the Wall was the job completed? How many months after the Wall began to be dismantled were the roads reopened? How many more excavators was the construction/demolition equipped with compared to bulldozers? How many more km of wall was removed compared to signal systems in Berlin? How many more kms was the border fence than the signal system? How many more trucks was the construction equipped with compared to excavators? How many more trucks were there than cranes? How many total GDR border guards and Pioneers of the Bundeswehr were involved in the demolition of the Bornholmer Straße all together? How many total combined trucks, cranes, excavators, and bulldozers were there that helped with the demolition of the Bornholmer Straße? How many total km of border fence and barrier ditches combined were removed in Berlin? How many total trucks, cranes, excavators and bulldozers were used in the demolition? How many years does this span? Was more km of wall or border fence removed in Berlin? Was the construction equipped with more trucks or cranes? Were more trucks or cranes used in the demolition? Where they equipped with more cranes or bulldozers used in the demolition of the wall and construction on the railway?
