What the heck is this? Zürich Hardbrücke station
Zürich Hardbrücke station:
There is this strange post on the side of the tracks at Zürich Hardbrücke station with what appears to be four broom brushes sticking out it. I saw this several times when commuting from Dietikon to Zurich HB and finally managed to take some photos (attached) on my last day there.
What could it be?
