Scope:
Note: The title and scope of this Notice of Intent (originally published on April 4, 2023) were updated by the responsible SDO on October 22, 2024.
1.1 General
This Standard provides a common set of safety indicators for use in process, operations, and safety management for passenger and transit railway systems in Canada.
1.2 Terminology
In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
1.3 Units of measurement
The values given in SI units are the units of record for the purposes of this Standard.
Note: See Annex D for a conversion table showing SI and non-SI units.
Project need:
This proposed National Standard of Canada is aimed at helping improve rail safety in Canada. It is being developed as the result of an extensive stakeholder engagement process and has been supported by members of the committee responsible for the existing CSA R114:22 - Canadian method for risk evaluation and assessment for railway systems standard as well as participants of a stakeholder workshop convened by CSA Group. This proposed standard is based on an existing European Union Agency for Railways regulatory framework which will be adapted to the Canadian context as was done to create the CSA R114:22 standard. This standard could be used by organizations with an objective of improving railway safety. This proposed New Standard is being developed supported by Metrolinx. It will provide the industry with common definitions and calculation methods for key safety indicators. This will meet the strategic needs of the following key interests: • Railway operators • Railway owners • Railway maintainers • Potential contractors • Railway regulators • Potential suppliers
