From TMZ:
People were milling about on the platform above … but no one seemed particularly concerned about their well-being. All of a sudden, the young man got electrocuted, his body was shaking and going rigid as he clung to the woman beside him. She, too, was jolted by the voltage -- and, subsequently, both went limp. A friend sitting next to them pulled them off the third rail before emergency service units arrived.
The two victims were rushed to a local hospital, where the unconscious man was in critical condition. The woman suffered less severe injuries and was said to be "improving." Their buddy was not seriously hurt. The trio reportedly jumped onto the tracks to take selfies while waiting for the train to take them to the Lollapalooza Festival in Grant Park on August 5.
Thankfully, these kids are alright, but seriously, you gotta wonder how anyone could think sitting on train tracks is a good idea, especially for a selfie...
