...we had met a railway fan from East Berlin during earlier steam locomotive tours in Berlin. He had given me a railroad time table of the Deutsche Reichsbahn, which unfortunately could not always be bought at every station.
In return, he asked me for a railroad time table from the Deutsche Bundesbahn. I have pointed out to him that I have to declare the time table on entry. It had a few hundred pages and weighed around 3 lb. It wasn't easy to hide it in your socks or underpants. For sure I would be asked for the details of the receiver of it. He agreed to give up his name and address on demand.
So I trudged through the snow to the Heinrich-Heine-Straße, where in the middle of a through road a border crossing divided a city into two different states. A strange idea today, that the Königsallee in Düsseldorf or the Prager Straße in Dresden would end at the border to another country.
After proper declaration of the items which I carried with me, I was brought into a windowless room and felt "soft-boiled" for at least half an hour before a nice gentleman asked me about harmless topics. The procedure took another good hour. I was not allowed to take the DB time table with me, because it probably violated the following regulation:
"Items not permitted on entry: literature and other printed matter the contents of which are directed against the maintenance of peace or the importation of which is otherwise contrary to the interests of the socialist state and its citizens."
Whether it was directed against the preservation of peace or otherwise contradicted the interests of the socialist state and its citizens, I did not dare to determine. After consuming many agent films, my guess was that there was a fear that secret codes might be hidden in the long rows of numbers. I received a receipt so that I could take the time table back with me in the evening when I left. Here the questioning started again: why, why, why, for whom etc. . In reply to my objection that his colleague had already noted everything down in the morning, I received the answer: "Nothing is being noted down here".
Well, see for yourself:
