La présente Norme européenne fixe des exigences concernant les attelages de secours des rames couvertes par la Spécification Technique d’Interopérabilité relative au matériel roulant a grande vitesse. Elle définit les interfaces auxquelles ils doivent correspondre pendant les opérations de secours. Elle convient aux locomotives équipées d’organes de chocs et de traction respectant la fiche UIC 520, c'est-a-dire possédant un crochet mobile et un appareil de traction supportant un chargement en compression )
Les dispositions qui dépassent le domaine d’application de la présente Norme européenne doivent faire l’objet d’un accord conclu par les parties contractantes intéressées.

EN 15020:2006 (E) 3 Foreword This document (EN 15020:2006) has been prepared by Technical Committee CEN/TC 256 “Railway applications”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of Directive 96/48/EC1), as amended by Directive 2004/50/EC2). For relationship with the EU Directive, see informative Annex ZA, which is an integral part of this document. The requirements on coupling interfaces of end couplers will be dealt with in a new work item. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

EN 15020:2006 (E) 4 1 Scope This European Standard specifies the requirements for the rescue coupler for train sets compliant with the Technical Specification for Interoperability High Speed Rolling Stock. It defines the interfaces to which it has to match during rescue operations. It is suitable for locomotives fitted with UIC 520 pattern draw gear and buffers, i.e. moveable draw hook and draw gear capable of compressive loading.3) Provisions going beyond the scope of this European Standard need to be agreed upon by the contracting parties involved. 2 Normative references The following referenced documents are indispensable for the application of this document.

The rescue coupler shall be compatible with: the Scharfenberg® system type 10 automatic coupler4) having the dimensions specified in Annex A and
the draw hook having the dimensions shown in Figure C.1. The main dimensions and characteristics of the rescue coupler shall be as given in Annex B. The mass of the complete rescue coupler in its operational condition shall not exceed 50 kg. The rescue coupler shall be able to withstand the following loads without permanent deformation: maximum tensile load = 300 kN; maximum compressive load = 250 kN. NOTE There are no fatigue requirements for the rescue coupler. The rescue coupler shall be equipped with handles or components which serve as such for transport and lifting. Material certificates and weld-classes used shall meet current requirements. Welded parts shall be in accordance with prEN 15085 and EN ISO 5817. 4.2 Rescue vehicle characteristics The rescue vehicle characteristics to be taken into account are defined as follows: connections for electric cables and air pipes on head stocks of locomotives (see Figure C.3); draw hook (see Figure C.1). Due to different markings located on both sides of the hook it is compulsory to consider a 2059+ mm hook width; pneumatic coupling for brake pipe and main air reservoir pipe (see Annex D). The rescue coupler pneumatic pipes and their connections shall be provided for a 10 bar pressure.

EN 15020:2006 (E) 6 4.3 Fitting procedure The rescue coupler shall be placed close to the front of the rescue vehicle. The rescue coupler shall be mounted on the draw hook. It shall be possible for the coupler to be lifted and mounted onto the draw hook of the rescue vehicle by no more than two persons. The available space around the draw hook of the rescue vehicle shall be taken into account. Mounting of the rescue coupler on the draw hook shall not require any special tools.
The coupler shall be secured to the draw hook with a fixing device in such a way that it cannot freely move or come off the draw hook during the rescue operation. Once the rescue coupler is mounted on the draw hook of the rescue vehicle: the installed rescue coupler shall have at least ± 6° vertical movement from the horizontal during operation; it shall be possible for the coupler to be adjusted vertically on the draw hook without the need for special tools; coupling and uncoupling operation shall not require any human presence between the rescue vehicle and the failed train unit or train set whilst either is being moved; the rescue coupler and the pneumatic
