Posted by Union Turnpike on Fri Sep 11 19:45:07 2009, in response to Re: Fourth Rails and Safety, posted by MGL on Fri Sep 11 19:30:45 2009. The London Underground uses this. The third rail is +420 VDC and the center return rail is -210 VDC. Not sure what might happen if someone got on the tracks at an Underground station. |
