Ever since I became an intermittent resident of Berlin nearly ten years ago, I have been mildly obsessed with this array of nearly two dozen bridges that carried various rail lines over Yorkstrasse and which have mostly been derelict since the war. I had always feared that they might be swept away by the tide of regeneration as the Gleisdreieck park to the north took shape from a huge abandoned marshalling yard but it seems that they will now be preserved, probably spruced up and painted and another piece of photogenic dereliction will be consigned to history.
