Overreliance on Visual Inspections May Have Contributed to GO Train Derailment: Report
Metrolinx said visual inspections missed degraded fasteners before the derailment, which disrupted commuter travel for days and led to automatic fare refunds.
- Metrolinx recently released a report confirming that a Transit train derailment at Toronto's Union Station on Feb. 2 was caused by missing screws on a railway track that disrupted commuter travel for days.
- Investigators found an overreliance on visual inspections contributed to the derailment, as they cannot "reliably determine the remaining holding strength or clamping effectiveness" of the screws. Metrolinx CEO Michael Lindsay described the issue as a "legacy infrastructure condition that developed progressively over time."
- Two screws were installed per plate at the site, though four were required under standards implemented last year. Consequently, the rail shifted about 3.5 centimetres after screws across nine consecutive timber ties became loose, missing, or degraded.
- During the board meeting on Sept. 10, Lindsay stated no crew errors or mechanical deficiencies caused the derailment. Metrolinx has since updated its protocols to strengthen inspections and issued automatic fare refunds to affected riders.
- The report notes annual geometry testing makes it difficult to spot fastening degradation between tests. "The combination of visually based inspections" and limited testing reduced the likelihood of identifying irregularities before they escalated into derailment risk.
