I'm in Lynnwood WA this week at a FEMA training and have been given the task of studying NS's 2005 Graniteville SC accident. If anyone has any background on the railroad's signal systems and operations involved in that accident, I'd greatly appreciate your input. I know it was caused by a switch that was not realigned by a switch crew, but am wondering how that line was dispatched then and if there were any preventive measures in place that were nonfunctional or overlooked by the road freight crew.
Thanks in advance,
Bryan
