(Main)Railway applications - Crashworthiness requirements for rail vehicles
Railway applications - Crashworthiness requirements for rail vehicles
This European Standard applies to new designs of locomotives and passenger carrying rolling stock as defined in categories C-I to C-IV of Clause 4 taking into consideration the recommendations given in Annex E on the application of the standard (migration rule). It is intended to protect vehicle occupants, through the preservation of structural integrity, and does not extend to other railway employees and customers who are not in vehicles, or to third parties. The specified requirements relate to the technical and operational conditions of use that prevail in the CEN member countries. The design of new vehicles for use in passenger trains is based on operations with compatible rolling stock that also meet this standard. It is recognised that operational requirements will require new crashworthy and existing non-crashworthy vehicles to exist in the same train unit but such combinations of vehicles are not required to comply with this European Standard.
The requirements apply to the vehicle body, and to those mechanical elements directly associated with it that may be used to absorb energy in a collision, such as couplers, buffing systems etc. They do not cover the safety features of doors, windows, system components or interior features except for specific issues relating to the preservation of survival space.
The requirements do not cover all possible accident scenarios but provide a level of crashworthiness that will reduce the consequences of an accident, when the active safety measures have been inadequate. The requirement is to provide a level of protection by addressing the most common types of collision that cause injuries and fatalities.
The applicable design collision scenarios, and suitable parameters for normal European operations, are given in Clause 5. Annex A gives additional information regarding the derivation of the scenarios and describes situations when they may need to be modified and the processes that should then be followed.

Applications ferroviaires - Exigences de sécurité contre collision pour véhicules ferroviaires
Le présent document spécifie les exigences de l’aptitude à la collision applicables aux nouvelles conceptions de :
locomotives ;
véhicules avec cabine de conduite en exploitation dans des trains de passagers et de marchandises ;
véhicules ferroviaires destinés au transport de passagers en exploitation dans des trains de passagers (tels que tramways, métros, trains de grande ligne).
Le présent document identifie les méthodes courantes de sécurité passive qui peuvent être adaptées pour convenir aux exigences particulières de chaque véhicule.
Le présent document spécifie les caractéristiques des modèles d'obstacles de référence pour les scénarios de collision de conception.
Le présent document spécifie également les exigences et les méthodes permettant de démontrer que les objectifs de sécurité passive sont atteints par comparaison avec les conceptions éprouvées actuelles, par simulation numérique, par des essais de composants ou des essais en grandeur réelle, ou une combinaison de toutes ces méthodes.
