DIN EN 16404:2016-05

This document is the generic standard for equipment for re-railing of damaged rail vehicles. Rail vehicles shall be designed so that re-railing and recovery operations after a derailment or accident can be safely undertaken without exposing persons to undue risk during lifting and jacking operations. For rolling stock of interoperable trains there is a need to define common requirements in terms of lifting and jacking operations, equipment space envelopes and lifting accessories. Foreseeable factors that can influence a re-railing or recovery operation include: - final vehicle position relative to the track; - weight transfer due to final vehicle orientation (inclination or roll); - vehicle load, possible overloading or uneven loading; - load movement or shifting; - embedding of parts of the vehicle in the ground; - sinking of jacks (soft ground); - structural distortion/damage; - jerking or snatching of lifting equipment. The majority of these factors cannot be quantified either in advance or during a recovery operation and therefore precise requirements cannot be set out in this standard and accordingly design scenarios are used. The resulting requirements together with competent persons undertaking the re-railing or recovery operation using the documentation specified are considered to be sufficient to ensure that the overall objectives are satisfied. This revision still includes explanations on the use of re-railing beams and support points as well as clearances for lifting equipment, requirements for lifting low-floor vehicles, requirements for crane use and an additional annex with a lifting device for loads up to 340 kN. This European Standard applies to all railway vehicles operating under the Interoperability Directive with consideration of the transitional arrangement (as annex in the document). Rolling stock of the following types are excluded from the scope of this standard: - metros, - tramways, and other light rail vehicles; - vehicles for the operation of local, urban or suburban passenger services on networks that are functionally separate from the rest of the railway system; - vehicles exclusively used on privately owned railway infrastructure that exist solely for use by the owner for its own freight operations; - vehicles reserved for a strictly local, historical or touristic use. On-track machines are in the scope of this standard only when in transport (running) configuration on their own rail wheels, either self-propelled or hauled. However, the requirements may be appropriate for other applications that have similar operational conditions. The standard specifies the principles and processes to be followed to achieve satisfactory arrangements for re-railing or recovery of railway vehicles and to validate the design against the relevant performance and safety requirements. The interface between the re-railing and recovery equipment and the vehicle structure is considered as the interface between the jack contact faces or the lifting bracket contact areas. The structural requirements for the vehicle structure are set out in EN 12663-1 and EN 12663-2. In addition to standard series EN 12663, references exist to EN 13155, EN 15663, standard series EN 15877 and EN 22768-1. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of Directive 2008/57/EC.
