FARGO, N.D. (AP) — Federal investigators say an oil train that derailed near Casselton, erupting in fiery explosions, was carrying its cargo in older-model tankers that have been prone to rupturing.
The BNSF Railway train went off the rails Monday, and officials asked residents of the small town near Fargo to leave due to concerns about air quality. No one was hurt, but the crash renewed concerns about oil train safety.
National Transportation Safety Board investigators say the tankers were older DOT-111s. Tanker makers have been building those to a tougher standard since a 2009 crash in Illinois, but retrofitting older models has been bogged down in bureaucracy.
The NTSB said the oil train was traveling from Mandan, N.D., to Dilworth, Minn., and had been on the road about eight hours before the derailment.
