The federal transportation safety board (TSB) investigation has found several track deficiencies that led to the 49-car CN train derailment on July 5 in Repentigny, Que.

The TSB said it has sent a rail safety advisory to Transport Canada to address “the condition of rail anchors on CN’s Joliette subdivision and is intended to inform the regulator of safety deficiencies identified that could pose a risk.”

The TSB team examined the area of the derailment and eight other sections of the track after the CN freight train, travelling 48 miles (78 kilometres) per hour, braked and cars derailed near residences in the suburb northeast of Montreal.

No one was injured, and no dangerous goods were spilled in the area.

The TSB investigation is continuing, and teams will “continue to analyze the information collected to identify the factors that caused or contributed to the occurrence, and the safety deficiencies that need to be addressed.”
