Ghost Tram

Day 4 of this trip to Vienna and although it was late when I finished work, I took a stroll around the city to clear my head and unwind, and to get a feel for the layout of the place. The immediate area near the office and hotel has a tram service with old-fashioned trolley cars. This 15-second exposure captures a moving tram so of course you can't actually see what it looks like. But you can see where it's been. I thought this was the more photogenic version :-)
