- Abstract
- This research addresses human error and the process standard EN 50126 Railway Applications - The Specification and Demonstration of Reliability, Availability, Maintainability and Safety (RAMS).
In Norway, it is required by The Railway Infrastructure Regulations to use the standard for new construction or changes to subsystems in the infrastructure. The standard is a harmonized standard which means that it provides presumption of compliance with requirements in relevant legislations. The standard aims to ensure continuous control of all aspects of Reliability, Availability, Maintainability and Safety (RAMS), by a consistent management. Clause 5.6.4 Human factors in the EN 50126-1:2017 provides information about human factors and is the...

In Norway, it is required by The Railway Infrastructure Regulations to use the standard for new construction or changes to subsystems in the infrastructure. The standard is a harmonized standard which means that it provides presumption of compliance with requirements in relevant legislations. The standard aims to ensure continuous control of all aspects of Reliability, Availability, Maintainability and Safety (RAMS), by a consistent management. Clause 5.6.4 Human factors in the EN 50126-1:2017 provides information about human factors and is the starting point of my document analysis.
The question is how the information about human factors and human errors is explained. Is this information sufficient to be able to understand the topic of human error?
Based upon the checklist in clause 5.6.4 Human factors, I carried out a document analysis where I used the checklist as a lens to explore the topic of human error.
The standard has been published in two editions, where risk assessments are addressed in a part 2 of the EN 50126-2:2017. Much of the fundamentals on which the standard rests upon have not changed. The division of risk assessments as a separate part, contributes, with its structural focus to human factors being taken out of the assessment. Between the first and the second edition of the standard, the railway sector has undergone major changes and regulations have been updated. This development is not easily reflected in the standard.
A fundamental objective of the standard is to contribute to a standardized process for managing RAMS. Its descriptions of the “V-model" as a management model combine three dimensions and it is up to the user to choose which one is emphasized.
The way human factors and errors are addressed, can lead to the assumption that using the checklist is all that is needed to derive human factors. The implication can thus be that human issues are taken too lightly, and we miss out on measures to optimize the system. (Less)
