ISO/DIS 22888


This document specifies the planning method for operational concepts, consisting of procedures and basic requirements for railway operation in regions where the exposure of railways to seismic hazard may not be negligible, in order to reduce customer risk due to earthquake occurrence. However, the definition of the above regions is out of the scope of this document.

This document defines the principles of planning in the occurrence of an earthquake and addresses the guidelines for planning of operational concepts by:

  • setting of the operational procedures in five stages, which consist of “1. detection of earthquake”, “2. judgment for operational restriction”, “3. operational restriction”, “4. inspection”, and “5. resumption of operational service” and describing the factors, elements, and/or conditions on which these procedures are based, and also

  • indicating the basic requirements for implementation of the above procedures in practice.

The operational procedures for the five stages will be underpinned by fundamental planning activities which support all stages.

This document includes only operational measures and excludes any infrastructure measures. Furthermore, this document does not include specific measures which ensure, without failure, passenger safety or provide protection against railway-operational damage caused by earthquakes, and therefore residual risk may remain.

Application of this document shall comply with the specific regulations applicable within the prevailing environment where the affected railway is located.
