Railway applications - Infrastructure - Demountable machines, trailers and associated equipment - General safety and technical requirements for travelling and working

This European Standard specifies the requirements for demountable machines and trailers, including road-rail trailers – henceforward referred to as ‘machines’.
This European Standard specifies the requirements to deal with the common hazards during transport, assembly and installation, commissioning, travelling and working on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines and associated equipment when they are used as intended and under conditions of misuse which are reasonably foreseeable; see Clause [tba].
This European standard deals with the requirements for the machine to be declared conformant by the manufacturer to the Machinery Directive (2006/42/EC), see Annex ZA, together with additional specific technical railway requirements.
These machines are not designed nor intended to operate signalling and control systems and are only designed and intended to work and travel under special operating conditions specifically designated by the infrastructure manager. These machines are not classified as ‘vehicles’ as defined in the Interoperability Directive 2008/57/EC and are not permitted to run on the railway lines open to normal traffic. Other machines are dealt with in other European Standards; see Annex [tba].
Additional requirements can apply for travelling and working on infrastructures with narrow gauge or broad gauge lines, lines of urban rail, railways utilising other than adhesion between the rail and rail wheels and underground infrastructures.
This European Standard is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.
The common hazards dealt with include the general hazards presented by the machines, as well as the hazards presented by the following specific machine functions:
- excavation;
- ballast tamping, ballast cleaning, ballast regulating, ballast consolidating;
- track renewal;
- rail maintenance;
- craning;
- catenary renewal / maintenance;
- maintenance of the components of the infrastructure;
- inspection and measurement of the components of the infrastructure;
- tunnel inspection / ventilation;
- shunting;
- emergency rescue and recovery;
This European Standard does not apply to the following:
- requirements for quality of the work or performance of the machine;
- specific requirements established by the railway infrastructure operator for the use of machines, which will be the subject of negotiation;
- separate equipment temporarily mounted on machines.
- machines that utilise the catenary for traction purposes;
- hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h
This European Standard does not establish additional requirements for the following:
- operation subject to special rules, e.g. potentially explosive atmospheres;
- hazards due to natural causes, e.g. earthquake, lightning, flooding;
- working methods;
- operation in severe working conditions requiring special measures, e.g. work in tunnels or in cuttings, extreme environmental conditions (below – 20 °C or above + 40 °C), corrosive environments, contaminating environments, strong magnetic fields;
- hazards due to errors in software;
- hazards occurring when used to handle suspended loads which may swing freely.
The maximum speed allowed for these machines is likely to be limited by the infrastructure manager; compliance with the clauses of this standard does not confer permission for machines to travel at this speed.
It is assumed that a finished standard automotive chassis used as a host for a demountable machine will offer an acceptable safety level for its designed functions before conversion. This specific aspect is not dealt with in this European Standard.

Applications ferroviaires - Infrastructure - Machines déraillables, remorques et éléments associés - Prescriptions techniques pour la circulation et le travail

Le présent document spécifie les exigences applicables aux machines déraillables et aux remorques, notamment les remorques rail-route – désignées ci-après les « machines ».
NOTE   Les remorques sont considérées comme des machines, car elles sont déplacées le long de la voie par des machines motorisées.
Le présent document spécifie les exigences pour traiter les risques qui se produisent couramment durant le transport, l'assemblage et l'installation, la réception, la circulation et le travail sur voie, l'utilisation (y compris montage, programmation et changement des procédés), l'exploitation, le nettoyage, la localisation des défauts, l'entretien et la radiation des machines et des équipements associés lorsqu'ils sont utilisés dans les conditions prévues et dans les mauvaises conditions d'emploi qui peuvent être raisonnablement anticipées ; voir 5.1.
Ces machines ne sont pas conçues ou prévues pour interagir avec les systèmes de signalisation et de commande en exploitation ; elles sont uniquement destinées à se déplacer et à travailler dans des conditions particulières d'exploitation conformément à celles généralement exigées par les gestionnaires d'infrastructure. Ces machines ne sont pas autorisées à circuler sur les lignes ferroviaires ouvertes au trafic normal. Les autres machines d'inspection de l'infrastructure et d'entretien ferroviaire montées sur rail sont traitées dans d'autres Normes européennes (voir Rapport technique 00256884).
Le présent document spécifie les exigences pour le déplacement et le travail sur tous les réseaux ferroviaires, y compris le réseau ferroviaire urbain. Des exigences supplémentaires peuvent s'appliquer pour la circulation et le travail sur les infrastructures ferroviaires à voies larges ou étroites, et sur les chemins de fer autres que ceux à adhérence rail/roue.
Le présent document s'applique aussi aux machines et aux équipements associés qui, en mode travail, prennent partiellement appui sur le ballast ou sur la plate-forme.
Le présent document ne s'applique pas :
—   aux exigences relatives à la qualité du travail ou aux performances de la machine ;
—   aux ajouts ou modifications apportés aux exigences du présent document et fixés par l'exploitant d'infrastructure ferroviaire ;
—   aux équipements distincts montés pour une durée temporaire sur des machines ;
—   aux machines utilisant la caténaire pour la traction ou comme source d'alimentation ;
—   aux phénomènes dangereux dus à la pression de l'air causée par le passage des trains à grande vitesse à plus de 200 km/h.
Le présent document n'entend pas non plus définir des exigences supplémentaires pour les aspects suivants :
—   mise en œuvre de la machine dans des conditions faisant l'objet de règles spéciales, par exemple atmosphère potentiellement explosive ;
—   risques dus à des causes naturelles, par exemple tremblement de terre, foudre, inondation ;
—   méthodes de travail ;
—   exploitation dans des conditions de travail sévères exigeant des mesures particulières, par exemple : conditions climatiques extrêmes (en dessous de - 20 °C ou au-dessus de + 40 °C), environnements corrosifs ou contaminants, champs magnétiques de forte intensité ;
—   dangers dus aux mouvements de charges librement suspendues susceptibles de se balancer.
