On March 15, National Transportation Safety Board officials investigating the cause of Monday’s derailment of Amtrak’s Southwest Chief on BNSF Railway near Cimarron, Kan., may have been caused by a large truck that impacted the tracks causing them to shift 12 to 14 inches off center. The train was traveling the regulated speed limit of 60 m.p.h. at the time, and the engineer applied the emergency brake as soon as he saw the damaged track ahead. The derailment injured 32 out of 131 passengers, and remains under investigation.
