Railway applications - Running capability in case of fire on board of rolling stock

Scope

This document describes methods by which an analysis to ensure the running capability of railway vehicles can be undertaken in cases where there may be an outbreak of a fire onboard.
This document specifies the fire conditions:
- for which it is not necessary to perform a running capability analysis, as there is no significant potential for serious injury or threat to life;
- for which it is reasonable to expect railway vehicles to continue to operate in a controlled manner;
- for which it is not reasonably practicable to give assurance of operating in a controlled manner, due to the exceptional nature of the fire incident.
This document does not consider situations where the train is immobilised by a primary event that is not related to fire, such as a major mechanical defect leading to, for example, a derailment, even if a fire consequently or subsequently occurs.
