question: How did Berlin work post WW2?
comment: There were roads, railways and canals, or you could fly. If you wanted to get between West Germany and West Berlin you need to cross the border twice, show your passport and then drive between. You weren't allowed off of the highway. You were searched to make sure you didn't pick up East Germans. I think you were timed as well. Between 24 June 1948 – 12 May 1949, all these routes were blockaded (except flying). So all food, goods, etc needed to be brought by air. 1500 flights a day to bring supplies.
passages: The early period of partition plans evolved by the European Advisory Commission is documented. When in February 1945, the United States, Great Britain, and the Soviet Union decided to split the former German Reich in occupation zones at the Yalta Conference, including a fourth area assigned to the French, the German capital likewise was divided into four sectors. In late April, Soviet Red Army troops fought their way into the city during the Battle of Berlin and enforced the unconditional surrender by the German Wehrmacht armed forces. In Summer they pulled out from the city's Western sectors according to the agreements concluded.

   Section::::Berlin.
   West Germany, formed on 23 May 1949 from the American, British, and French zones, had its seat of government and "de facto" capital in Bonn, although Berlin was symbolically named the "de jure" West German capital in West German Basic Law (Grundgesetz).
  
  West Berlin "de jure" remained under the rule of the Western Allies, but for most practical purposes was treated as a part of West Germany; however the residents did not hold West German passports.
  
  Section::::West and East Germany (1945–1990).:Blockade and airlift.
   Section::::Subsequent events.:Other developments.
  
  In the late 1950s, the runways at West Berlin's city centre Tempelhof Airport had become too short to accommodate the new-generation jet aircraft, and Tegel was developed into West Berlin's principal airport. During the 1970s and 1980s Schönefeld had its own crossing points through the Berlin Wall and communist fortifications for western citizens.
   Until they had devised a new, permanent headquarters, the Kommandatura met in the Soviet sector for several weeks, in rooms of the Soviet Central Kommandantur. Shortly thereafter the new headquarters was ready to be occupied, and on July 25, 1945, the Kommandatura met at Kaiserswerther Str. 16-18 in Berlin-Dahlem for the first time. The building was in constant use as Kommandatura headquarters until March 15, 1991, when the Two Plus Four Agreement went into effect.
   At the time of the beginning of World War II, with the German invasion of Poland in 1939, construction was suspended, but started again after the clear German victory. When France was defeated in 1940, and Hitler visited Paris for a short period with Speer and a few chosen others, the Führer's desire to "give Berlin a new face" was revitalized, and the work was redoubled at his command. At Speer's instigation, Hitler signed a decree which read: 
   Following the military occupation of Germany in May 1945, civilians were initially only allowed to leave their place of residence or its immediate vicinity with a permit from the garrison authority of their zone. By June 1945, the bus and train service within the respective garrison zones had been resumed on many stretches. However, the public train service did not run between the garrison zones. Nevertheless, there were numerous travelers who crossed the extensive uncontrolled boundaries between the garrison zones on foot, by bicycle or by hitch-hiking.
   The Soviets fought for and captured Berlin by the beginning of May 1945, and set up camp not only their own sector, but took control over the whole of Greater Berlin. The U.S. and British entered Berlin later, on July 1, and July 24, respectively. By that time the Soviets had plundered and pillaged the western sectors of Berlin. They had removed vital industrial infrastructure on a wholesale scale, and had taken most of what was left in the city in terms of agriculture and livestock.

   Section::::History.:Wartime implementation of the plan.
  
  After the start of military operations and the fall of the capital into German hands the project was updated, incorporating the city's partial destruction in the September offensive of 1939. The project was soon to be included as a part of the overall Germanization plan of the East, the genocidal Generalplan Ost.

   U.S. forces generally held onto these gains within Germany until July 1945, when under orders from President Harry S. Truman, and against the advice of British Prime Minister Winston Churchill the U.S. forces withdrew to the Yalta agreement boundaries dividing Germany into occupation zones. It is worth noting that the Soviet Union may not have allowed American and British forces into Berlin, which was completely under their control, if the U.S. had not honored the Yalta agreement boundaries. The German areas relinquished by American troops became part of the Soviet-dominated East Germany.
   The "Rüstungsstab" assumed responsibilities for the underground transfer projects of the "Jägerstab". In November 1944, 1.8 million square meters of underground space were ready for occupancy, encompassing over 1,000 spaces commissioned by the task force. According to the historian Marc Buggeln, the "Rüstungsstab" played a key role in maintaining and increasing production of fighter aircraft and V-2 rockets. 
   The book opens with a description of the siege and fall of German Breslau at the very end of the Second World War. The attacking Red Army reduces many streets of the city to rubble, the remaining Germans gradually withdraw. The hopeless situation of the civilians, complicated by shelling, temperatures of minus 20 and food shortages, deteriorates still further as revenge-seeking Soviet military leaders allow mass murder, rape and looting.
   The Council had held its final meeting on 2 October 1990, on the eve of the reunification of Germany, when it promulgated the formal documents – already agreed in advance – that authorized the inclusion of the city of Berlin in the German reunification. This was necessary because, until then, West Berlin was legally not a part of the Federal Republic of Germany, although it was administered by it. But with the allied Souveränitätserklärung (Sovereignty Declaration) agreed in the Council, the Federal Republic was allowed to assume legal control of Berlin at the moment of German reunification (although the withdrawal of the Allied military presence had to wait until 1994, in accordance with the timeframe provided by the Treaty on the Final Settlement with Respect to Germany).
   The U.S. commandant, Major General Floyd L. Parks, tasked his divisional G5 and later deputy, Colonel Frank L. Howley, to prepare a general plan for the basis of an Allied Kommandatura, based on a Russian proposal. Howley had arrived in Berlin July 1, 1945, as leader of the joint U.S.–British Military Government detachment, although the U.S. didn't take over their sector officially until July 12, when the Russians finally moved out. By this time the French had also obtained their own sector in the north of Berlin, carved out of the British sector, but were not invited to participate in the initial meetings.

   Berlin also is headquarters to the key government ministries for Air and Space, Justice, Interior, Transport, Food, Economics, Colonial, the Oberkommando der Wehrmacht, and the Führer's Office.
   However, after serious setbacks in the German invasion of the Soviet Union, which Hitler had initially seen as another "blitzkrieg" ("lightning war"), construction on "Germania" was halted for good in March 1943.
