The minutes of the December 8th, 2017 Board meeting were published: <a href="http://metrolink.granicus.com/AgendaViewer.php?view_id=3&clip_id=413">http://metrolink.granicus.com/AgendaViewer.php?view_id=3&clip_id=413</a> No word about the reasons of #907's breakdown at its November 18th, 2017 unveiling at Newhall Station. Regarding the reported urea problems there is the following information. The primary failure mode was a failure to transport the urea to the day tank. Quote page 370: Two failure modes were observed: failure of "gating solenoids" to open - restricting urea flow from storage tank & "loss of prime" preventing transfer pump from pumping urea fluid from storage tank up to day tank. And analogous: Since a second modification addressing these failures the units have each run about 700 miles each without additional failures. Staff expects to remove the stop order if recent reliability gains continue. Regards, Volker
