Central Alberta Train Derailment Prompts Calls for Enhanced Analytics of Railcar Wheels
The agency says 1 million older wheels remain in service and better use of detector data could help prevent future derailments.
- On Thursday, the Transportation Safety Board recommended the rail industry use enhanced analytics on sensor data to identify failing wheels, following a 2023 derailment near Uncas, Alberta.
- The recommendations stem from an April 5, 2023, derailment where 18 Canadian National Railway Company grain cars left the tracks near Uncas, caused by a shattered rim on a wheel manufactured in 1991.
- Despite multiple visual inspections, no issues were identified before failure; TSB Chair Yoan Marier noted sensors failed to identify the increasing impact trend preceding "catastrophic rim failure."
- Approximately one million wheels manufactured before 2003 remain in service across Canada and the United States; Marier stated most are likely safe, though they carry greater failure risk.
- Transport Canada stated it will provide a formal response to the TSB within the timeline mandated by the Canadian Transportation Accident Investigation and Safety Board Act, emphasizing rail safety commitment.
