Posted by handbrake on Wed Jul 4 18:06:16 2012, in response to Official Stance on What to do if someone Falls on the Tracks?, posted by E and F and sometimes J on Wed Jul 4 09:42:43 2012. "My reasoning is, that if you immediately try to pull the person up you waste critical time before the train enters the station and the third rail re-energizes and you will end up with the person being run over or electrocuted." Why are you under the impression that the contact rail will re-energize when a train enters the station? Regenerative braking? The contact(3rd) rail is always energized (Hot), and available to power traction equipment, bank of lights, or other ancillary DC devices. What is you impression of how NYC subway traction power is taken from the contact rail? |
