"Gleisdreieck" Where Geometry Surrounds You

Gleisdreieck  translates as track triangle & is a UBahn station in the Kreuzberg area .Lines 1 and 2 cross here and come from underground to travel overground (for a few stations) The geometry of this station is amazing which ever way you look. I had lots of fun taking loads of images ... The weather was sunny if a tad chilly .
