ISO/TC 269/SC 3/WG 1 - Planning of operational concepts for earthquakes

This document specifies the concepts and basic requirements for the planning of railway operation in order to reduce risk in the event of earthquakes. This excludes regions where the consequences of seismic hazard for railway operation are low or non-existent. The definition of such regions is out of the scope of this document. NOTE The stages defined for consideration of the countermeasures necessary for the safe management of the seismic hazards can also be relevant for dealing with other natural phenomena. This document includes only operational measures and excludes any infrastructure measures. Furthermore, this document does not include specific measures which ensure, without fail, passenger safety or which provide protection against railway-operational damage caused by earthquakes. Therefore, residual risk can remain.

In order to reduce the impact of predictable natural hazards on railway operation, this document specifies a general concept and basic requirements for the planning of railway operation in the events of predictable natural hazards, focusing on rainfall and strong wind. The given concepts and basic requirements do not apply to regions where the consequences of the addressed predictable hazards for railway operation are low or non-existent. The definition of such regions is out of the scope of this document. This document includes measures directly related to railway operation to reduce the impact in the events of predictable natural hazards. Furthermore, this document does not include specific measures which ensure passenger safety or which provide protection against railway-operational damage caused by the predictable natural hazards. Therefore, residual risk can remain.
