The Third Rail of Politics
WARNING: DO NOT ATTEMPT THIS YOURSELF. THIS DEMONSTRATION HAS BEEN PERFORMED BY TRAINED PROFESSIONALS!!!
“Q Can RDT be installed on electrically live rails?
A Yes, RDT can be installed on energized rails. Track outages are disruptive to train schedules; therefore, heating cables are typically required to be installed on live rails.”
SO I GUESS YOU CAN TOUCH A THIRD RAIL, IF YOU KNOW WHAT YOU ARE DOING!
