The ticket inspector fell right on the rails due to an electric shock. He is being treated in hospital in critical condition.
Or another idea, since no cable is seen loose or around the person. Directed Energy Weapon hit person. (Nanite electron energy weapon) are we living in a period of weapons from above, or handheld can do damage. This is real.
