More information has come out after a scary incident last month.
A CN train derailment in Sturgeon County was caused by “fracture defects” that had been identified in a prior inspection.
Twelve loaded cars derailed while travelling south, with two tank cars leaking over 50 litres of oil.
The Transportation Safety Board released a statement saying “the rail was scheduled to be replaced."
CN had known of the poor rail conditions.
The statement added the curve in the rail had “exceeded its rail wear limits" including defects to the curve and a bolt hole.
