TSB calls for stricter rules on medical fitness assessments after Alberta train crash
The Transportation Safety Board (TSB) urges the Canadian government to enhance oversight of railway medical fitness assessments. This follows an investigation into a 2023 collision involving Canadian National Railway (CN) trains, where an engineer with incomplete diabetes assessments was cleared to work. The TSB found gaps in CN's medical evaluations and no audits by Transport Canada in 12 years.
