I talked to a friend who mentioned reading a theory about the placement of terminal vs passthrough train stations in Germany.
In this theory, the Prussians were responsible for this decision during the Second Reich. If a city was considered "friendly", it got a pass-through station. If the Prussians disliked a city for some reason, they made a terminal train station there, hoping to diminish its chances of becoming an important railway junction and thus subtly depriving it of economical and political importance.
According to this theory, later train stations were mostly built as pass-through stations, because nobody used the building of terminal stations as a political instrument.
Is there any support for this theory? Is it widely known among historians, or just idle musings of some popular science writer? If it is known, is there support for it, and how solid is it? What alternative theories exist for terminal stations?
Explanation of terms: A terminal station is where trains end, they cannot pass through it. The tracks enter the station building and end there. A pass-through station is one which has the tracks beside the building, and trains enter from the one side and continue on the other.
