The third is not live constantly only gets you if you touch the third rail and another metal completing the circuit and shocked to death As kids we used walk the third rail for a hits and giggles . . you can walk it just don't touch anything else . 2 feet on the third rail no problem 1 foot on one foot on another rail huge mistake. Did he fall or !!!???. Walking the tracks still safer than train surfing!

So you have the two rails the train travels on, and then a third "rail" which is really just a thick (like, several inches thick) wire carrying about a thousand amps of current. The train has another wire that drags along this third rail as it moves, drawing current and making the motor moves.

Since it takes about 1 amp of current to kill a person, touching the third rail is usually a pretty quick way to get yourself killed.
