Extreme graffiti or ghost tram in The Hague?

There I was, huffing and puffing my way along the luxury 2 metre wide cycle path  (Boris please take note, that´s how it should be done!) and I was overtaken by a ghost. I mean,  I am used to  being overtaken by The Hague´s swish blue-liveried super-luxury trams travelling at 15 km per hour, yes a bit pathetic, but  I do it to get fit not because I am fit. And there it was, the silver lightening vision, gliding along, windowless and totally different. Lots of locals turned their heads at the vision, but only I had the inspiration, or the time to waste, to jump/fall off my bike and take some photos.
