Rail transportation safety letters and concerns

Safety concerns

Safety concerns provide a marker to the industry and the regulator that the Board has identified a safety deficiency for which it does not yet have sufficient information to make a recommendation. As more data and analysis become available, and if the safety deficiency is found to be systemic and not redressed, the safety concern may lead to a recommendation. Safety concerns are usually communicated in final investigation reports.

Safety information letters

The TSB sends safety information letters to regulatory and/or industry stakeholders to advise them of potentially unsafe acts or conditions identified during an investigation that pose low risks and do not require immediate remedial action. The letters aim to promote safety or clarify issues that a stakeholder is already examining, and are sent before the investigation has been completed. Those that do not contain privileged or proprietary information are posted here.

Safety advisory letters

Safety advisory letters are concerned with safety deficiencies that pose low to medium risks, and are used to inform regulatory or industry stakeholders of unsafe conditions. A safety advisory letter suggests remedial action to reduce risks to safety.
