For anyone who has lived in Germany for the past several decades, this House of the History of the Federal Republic of Germany brings back lots of personal memories. For instance this water truck, which was used by the police in the 1960s and 70s (and still is today, as far as I know) to disperse illegal demonstrations.
Second photo: No, this isn't the railway station, it's an exhibit (in the museum basement) of the salon car that was used by the first four West German chancellors Konrad Adenauer, Ludwig Erhard, Kurt Georg Kiesinger and Willy Brandt for their travels around Germany and Europe in the 1950s, 60s and 70s.
Third photo: Some original sections of the Berlin Wall are on display on the top floor of the museum, along with a video installation showing the events leading up to the breaching of the wall in 1989.
Fourth photo: The lobby and cafe in the House of the History of the Federal Republic of Germany.
This is the history museum of Germany. It has lots of photos and other exhibits like cars, train compartments etc on display. The train in the photo is not a train in any station but an exhibit of the train that used to be in the earlier days on display in the ground floor of the museum. The photo shows the new Deutsche Mark post reunification of Germany. It is a big museum and the good thing about it is that it has no fee for entrance. The only thing I did not like was the absense of information in English. Everything is very German. To go to the museum one needs to get down at Heussallee station of U-bahn and just follow the exit directions. One can directly enter the museum from one of the exits without going out of the station.
