Railway applications - Infrastrucutre - Demountable machines, trailers and associated equipment - Part 1: Technical requirements for travelling and working

This document specifies the requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as ‘machines’.
NOTE   Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines.
This document specifies the requirements to deal with the common hazards presented by their use on the railway 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.
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 in accordance with those permitted by the infrastructure managers. These machines are not permitted to run on railway lines open to normal traffic.
NOTE   Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020.
This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.
The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s).
This document does not apply to the following:
-   requirements for quality of the work or performance of the machine;
-   use of separate equipment temporarily mounted on machines;
-   machines that utilize the overhead contact line system for traction purposes or as a power source;
-   hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h
-   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. corrosive environments, contaminating environments, strong magnetic fields;
-   hazards occurring when used to handle suspended loads which may swing freely.

Dieses Dokument legt die Anforderungen für ausgleisbare Maschinen und Anhänger, einschließlich Zweiwege-Anhänger, die nachfolgend als "Maschinen" bezeichnet werden, fest.
ANMERKUNG   Anhänger, einschließlich Zweiwege-Anhänger, werden als Maschinen angesehen, da sie von angetriebenen Maschinen auf dem Gleis bewegt werden.
Dieses Dokument beschreibt die Anforderungen, wie mit den üblichen Gefahren durch ihre Verwendung auf Bahngleisen während des Transports, der Montage und Installation, der Inbetriebnahme, der Versetzfahrt und Arbeiten im/am Gleis, der Nutzung einschließlich der Einstellung, Programmierung und Verfahrensumstellung, des Betriebs, der Reinigung, der Fehlersuche, der Wartung und der Außerbetriebnahme der Maschinen und der zugehörigen Ausrüstung bei bestimmungsgemäßer Verwendung und unter vernünftigerweise vorhersehbaren Fehlanwendung umzugehen ist.
Diese Maschinen sind weder für den Betrieb mit Signal  und Zugsicherungssystemen konstruiert noch vorgesehen. Sie sind nur für den Arbeitseinsatz und die Versetzfahrt bei besonderen Betriebsbedingungen in Übereinstimmung mit den durch die Infrastrukturbetreiber zugelassenen Betriebsbedingungen konstruiert und vorgesehen. Diese Maschinen dürfen nicht auf Eisenbahnstrecken eingesetzt werden, die für den normalen Verkehr freigegeben sind.
ANMERKUNG   Andere schienengebundene Eisenbahninstandhaltungsmaschinen und Maschinen zur Inspektion der Infrastruktur werden in anderen Europäischen Normen behandelt, siehe CEN/TR 17498:2020.
Dieses Dokument gilt auch für Maschinen und zugehörige Ausrüstungen, die sich in Arbeitsmodus teilweise auf dem Schotter oder dem Untergrund (Planum) abstützen.
Die Anforderungen in dieser europäischen Norm basieren auf der Annahme, dass die Maschinen von geschultem Personal benutzt, bedient und gewartet werden.
Dieses Dokument gilt nicht für:
-   Anforderungen an die Qualität von Arbeiten oder die Leistung der Maschine;
-   Verwendung von separater Ausrüstung, die vorübergehend an Maschinen montiert ist;
-   Maschinen, die die Oberleitungsanlage für Antriebszwecke oder als Energiequelle verwenden;
-   Gefahren verursacht durch Luftdruckstöße von vorbeifahrenden Hochgeschwindigkeitszügen mit mehr als 200 km/h;
-   Einsätze, die besonderen Regeln unterliegen, z. B. explosionsgefährdete Umgebungen;
-   Gefahren aufgrund natürlicher Ursachen, z. B. Erdbeben, Blitzschlag, Überschwemmung;
-   Arbeitsverfahren;
-   Betrieb unter schwierigen Arbeitsbedingungen, die besondere Maßnahmen erfordern, z. B. korrosive Umgebung, kontaminierte Umgebungen, starke Magnetfelder;
-   Gefahren durch freischwebende Lasten, die schwingen können.

Applications ferroviaires - Infrastructure - Machines déraillables, remorques et éléments associés - Partie 1 : Prescriptions techniques pour le déplacement et le travail

Le présent document spécifie les prescriptions applicables aux machines déraillables et aux remorques, notamment les remorques rail-route - désignées ci-après les « machines ».
NOTE   Les remorques, y compris les remorques rail-route, sont considérées comme des machines, car elles sont déplacées le long de la voie par des machines motorisées.
Le présent document spécifie les prescriptions pour traiter les phénomènes dangereux courants induits par l'utilisation de ces machines sur l'infrastructure ferroviaire 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 le démantèlement 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.
Ces machines ne sont ni conçues ni prévues pour interagir avec les systèmes de signalisation et de contrôle ; elles sont uniquement destinées à se déplacer et à travailler dans des conditions d'exploitation particulières conformément à celles autorisées par les gestionnaires d'infrastructure. Ces machines ne sont pas autorisées à circuler sur les lignes ferroviaires ouvertes au trafic normal.
NOTE   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 CEN/TR 17498:2020.
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.
Les prescriptions du présent document reposent sur l'hypothèse que les machines sont utilisées, exploitées et entretenues par des personnes qualifiées.
Le présent document ne s'applique pas :
-   aux prescriptions relatives à la qualité du travail ou aux performances de la machine ;
-   à l'utilisation d'équipements distincts montés pour une durée temporaire sur des machines ;
-   aux machines utilisant le système 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 ;
-   à la mise en œuvre de la machine dans des conditions faisant l'objet de règles spéciales, par exemple atmosphère potentiellement explosive ;
-   aux phénomènes dangereux dus à des causes naturelles, par exemple tremblement de terre, foudre, inondation ;
-   aux méthodes de travail ;
-   à l'exploitation dans des conditions de travail sévères exigeant des mesures particulières, par exemple environnements corrosifs ou contaminants, champs magnétiques de forte intensité ;
-   aux phénomènes dangereux dus aux mouvements de charges librement suspendues susceptibles de se balancer.

Introduction

The machinery concerned and the extent to which hazards, hazardous situations and events are covered

are indicated in the scope of this document.

This document is the first of a series of two parts of the European Standard: Railway applications —

Track — Demountable machines, trailers and associated equipment, dealing with railway specific risks of

the demountable machines and trailers when travelling and working on railway infrastructures:

— Part 1 covers the safety and technical requirements for the machines in travelling and working

modes, and is applicable for all machines, including those in operation on urban rail;

— Part 2 covers the safety requirements for the machines in travelling and working modes; this is a

document harmonized with the European Machinery Directive 2006/42/EC.

Part 1 defines requirements for approval of the machine for use on the railway. Depending on the decision

of the Infrastructure Manager, Urban Rail Manager or the requirements in National rules the assessment

of conformance could be undertaken by the Infrastructure/Urban Rail Manager concerned, by a third

party assessor or by the manufacturer as a declaration of conformity.

Part 2 defines requirements for the machine to be declared conformant by the manufacturer, except in

the case of machines classified under Annex 4 of the Machinery Directive, which require a conformity

check in conjunction with a notified body.

The hazards which exist in all mechanical, electrical, hydraulic, pneumatic and other components of

machines and which are dealt with in the relevant European standards are not within the scope of this

document. Where necessary, references are made to appropriate standards of this type.

1 Scope

This document specifies the requirements for demountable machines and trailers, including road-rail

trailers – henceforward referred to as ‘machines’.

NOTE Trailers, including road-rail trailers, are considered as machines because they are moved along the track

by powered machines.

This document specifies the requirements to deal with the common hazards presented by their use on

the railway 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.

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 in accordance with those

permitted by the infrastructure managers. These machines are not permitted to run on railway lines open

to normal traffic.

NOTE Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other

European standards, see Technical Report CEN/TR 17498:2020.

This document is also applicable to machines and associated equipment that in working mode are partly

supported on the ballast or the formation.

The requirements in this document are based on the assumption that the machines are used, operated

and maintained by skilled person(s).
This document does not apply to the following:
— requirements for quality of the work or performance of the machine;
— use of separate equipment temporarily mounted on machines;

— machines that utilize the overhead contact line system for traction purposes or as a power source;

— hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;

— 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. corrosive environments,

contaminating environments, strong magnetic fields;
— hazards occurring when used to handle suspended loads which may swing freely.
