Well, as best as I can determine, here's what happened. Just before the morning rush on 11/6/07 the frist light rail set was trying to leave the 7000 South Trax maintenance facility (note this is not the ex-UP Frontrunner facility north of town), when the lead light rail unit somehow fowled its pantograph (Trax uses lubricant impregnated pantographs, don't know if that had anything to do with it), causing an arc and a fire, partially damaging unit 1013, and plugging the lead out of the ready yard for about two hours. There was essentially no Trax service for about 2 hours - during the morning rush. The Siemens units have pantograph troubles every now and then (I've witnessed them). That's about it for now.
