National Boundary Between Belgium and Germany

　　I sometimes have to stay awake at midnight in my office. It's a fulfilling task to save the lives no matter what the circumstances are, but just waiting for the mortal moment of incurable patients is nothing but a pain and it makes me sleepy. Reading books isn't helpful in such cases.
　　Netsurfing is useful to me for warding the sleepiness off at midnight. I suppose that it's because netsurfing has something active in its nature whereas reading is a simply passive act.
　　I had such a time last night and found an amazing fact. Guess what!? I was viewing Germany on the Google Map. The boundary line between Belgium and Germany was double! There were two boundary lines and the train tracks were built between the two. The area in which train tracks run was the territory of Belgium, and the both sides of the tracks were German territory. Why on earth was such a situation born? Probably, it has some serious or historical issues. I'd really like to know the cause of the double boundary lines.
　　I'm learning German now and am attending a German class twice a month. I'm going to ask the teacher about this fact in the next class, but I have to explain it in German. It's another problem.

What a great reason to study! Learning how to ask about the railroad will be a great experience in studying the language.
