Posted by Sand Box John on Sun Jul 8 00:04:13 2012, in response to Re: Passenger Accounts Re: Stalled WMATA Green Line Train ''Self-Evacuated'' by Its Passengers, posted by RockParkMan on Sat Jul 7 14:04:02 2012. Lamp indication is not considered positive indication of a dead third rail. Lamps can tell you that the rail is "hot" if they are on but if the lamps are out it may just be that a lamp is "burned out" thereby "killing" the other 4 lamps in the series string. 5 120 volt lamps in series equal a 625=volt lamp array. These lamps when lighted POSITIVELY tell you the track is "hot" but tell you NOTHING either way if they're "out".WMATA does not have lights wire in series connected to the third rail to indicate if the third rail is energized. Anyhow, it turn out my previous remark was incorrect. The evacuation video clip of the Green line derailment clearly shows the blue light that marks the emergency trip station / phone box were on as passengers were walking from the derailed train to the emergency exit. 1:09 to 1:40 John in the sand box of Maryland's eastern shore. |
