God I hope they graffiti the robot dogs as well because that would be so funny.

They will. We're talking of poeple that have no problem stopping a train in a busy station to completely paint it from one side to the other. They'll spray the dog, put a couple stickers on it, and run away.

Your tax Euros at work: Buying useless expansive robot dogs.

I'm confused - how do the vandals stop the train?

Like this:

TL;DW: Basically, the conductor alerts the police and stops the train, once they realize that the train is being decorated. If they started moving forward, it could seriously endanger the graffiti sprayers. So that's really the best course of action here.

If one graffiti artist delays my train for one minute, that’s one minute too many

Is outrage somehow a rational reason for anything?

ego much? if they get hurt, train is delayed, if they don't get hurt, train is delayed. you cannot win.

Well, you might assume that they only get hurt once. Maybe it would make their co-conspirators re-evaluate their actions too...

Whoa, TIL that suspension railways exist!

My first thought after seeing the end of the video was "why is this video flipped?" until I realized that it was only the train that was "upside down".

But who do they deploy when the robot dogs get out of hand?
