Also imagine the situation, you are in a foreign country. Some guy in strange clothes waves a sword at you and shouts something you cannot understand.

What do you think you would do?

Laugh?

Don't think so.

Pull out a gun and shoot him? Well maybe in Texas.

Hit him as hard as you can? Yes, in most places in the UK

Give him a 'Glasgow kiss' ? Nobody would ever be stupid enough to pull this stunt in Glasgow.

Would love to see someone try that on the Caltrain in the Bay Area.

Total nincompoop, for reasons already stated by Stainless.

If you're going to do a real-life prank, at least do something like the guy who did the RE 4 "What are ya buying? What are ya selling?" thing in a mall.

Or the "Real Life Mariokart".

If he tried that on the train line I ride to and from work every day, he'd probably be killed by the train on account of the fact that our light rail (the SkyTrain) is pretty much fully automated. Either that or electrocute himself on the 3rd rail.

Either that or electrocute himself on the 3rd rail.

No joke, both the voltage (typically 750V) and the currents (several hundred to a thousand A, given typical 600-800 kW motors) on these are far beyond what you would wish to have go through your legs.

Note that the power network easily supports two or three trains running behind each other (a kind of regular thing when there is a delay), so the actual supported currents must be in yet another ballpark. I really wouldn't rely that the cutout switch goes off early enough when you're playing the short circuit.
