(Main)Railway applications - Track - Road-rail machines and associated equipment - Part 1: Technical requirements for travelling and working
Railway applications - Track - Road-rail machines and associated equipment - Part 1: Technical requirements for travelling and working
1.1 General
This document deals with the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, operation and maintenance of the machines when carried out in accordance with the specification given by the manufacturer or his authorized representative.
These risks are normally common regardless of the track gauge. However, additional requirements can apply for travelling and working on infrastructures with narrow gauge or broad gauge lines, railways utilizing other than adhesion between the rail and rail wheels and underground infrastructures.
This document is also applicable for machines and associated equipment that in working configuration are partly supported on the ballast or the formation. Such machines are capable of independent self-propelled movement on the ground.
This document does not apply to the following:
- the requirements for quality of the work or performance of the machine;
- the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the Infrastructure Manager;
- moving and working while not on rails;
- separate machines temporarily mounted on machines and associated equipment;
- demountable machines as defined in 3.2;
- trailers as defined in 3.3, including road-rail trailers.
Vehicles which are not track-guided themselves but have attachments that are track-guided are not road-rail machines.
The requirements within this document are amended and added to by the requirements in EN 15746 4 for machines designed and intended to use urban rail.
This document does not establish the 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 such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields;
- hazards due to errors in software;
- hazards occurring when used to handle suspended loads which may swing freely.
For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a particular clause this specific aspect is not dealt with in this European Standard.
Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex F.
1.2 Validity of this document
This document applies to all machines which are ordered one year after the publication date by CEN of this document.
Bahnanwendungen - Oberbau - Zweiwege-Maschinen und zugehörige Ausrüstungen - Teil 1: Technische Anforderungen an die Versetzfahrt und den Arbeitseinsatz
1.1 Allgemeines
Dieses Dokument behandelt die technischen Anforderungen zur Minimierung eisenbahnspezifischer Gefährdungen von selbstangetriebenen Zweiwege Maschinen – im Folgenden als Maschinen bezeichnet – und ihrer zugehörigen Ausrüstungen, die bei der Inbetriebnahme, im Betrieb und bei der Instandhaltung auftreten können, wenn sie den Anweisungen des Herstellers oder seines autorisierten Vertreters entsprechend erfolgen.
Diese Risiken sind in der Regel unabhängig von der Spurweite. Allerdings können zusätzliche Anforderungen für Versetzfahrten und den Arbeitseinsatz auf Schmalspur- oder Breitspurstrecken, auf Bahnen, die andere Kräfte als die Adhäsion zwischen Rad und Schiene nutzen und U-Bahn-Infrastrukturen verwenden, gelten.
Dieses Dokument ist auch anzuwenden für Maschinen und ihrer zugehörigen Ausrüstungen, die sich bei ihrem Arbeitseinsatz zum Teil auf dem Schotter oder dem Planum abstützen. Solche Maschinen sind in der Lage, selbständige selbstfahrende Bewegungen auf dem Planum/Erdreich durchzuführen.
Dieses Dokument ist nicht anzuwenden für:
- Anforderungen an die Qualität von Arbeiten oder an die Leistung der Maschine;
- spezielle Anforderungen für die Nutzung der Maschinen, festgelegt von dem Maschinenbetreiber, die der Absprache zwischen Hersteller und Infrastrukturbetreiber unterliegen;
- Fahren und Arbeiten auf anderen Untergründen als auf Schienen;
- gesonderte Maschinen/Geräte/Anlagen, die vorübergehend an Maschinen und zugehörige Ausrüstungen angebaut sind;
- ausgleisbare Maschinen nach 3.2;
- Anhänger nach 3.3, einschließlich Zweiwege Anhänger.
Fahrzeuge, die nicht selbst über eine Schienenführung, aber über schienengeführte Zusatzteile verfügen, sind keine Zweiwege Maschinen.
Die Anforderungen in diesem Dokument werden durch die Anforderungen an Maschinen, die für den Einsatz auf Schienennahverkehrssystemen bestimmt sind, in EN 15746 4 geändert und ergänzt.
Dieses Dokument legt nicht die zusätzlichen Anforderungen für Folgendes fest:
- Einsätze, die besonderen Regeln unterliegen, z. B. explosionsgefährdete Umgebungen;
- Gefährdungen aufgrund natürlicher Ursachen, z. B. Erdbeben, Blitzschlag, Überschwemmung;
- Arbeitsverfahren;
- Einsätze unter schwierigen Arbeitsbedingungen, die besondere Maßnahmen erfordern, z. B. bei Arbeiten in Tunneln oder in Streckenabschnitten mit außergewöhnlichen Bedingungen wie Einsatz bei Frost, hohen Temperaturen, korrosiver Umgebung, tropischer Umgebung, kontaminierter Umgebung, starkem Magnetfeld;
- Gefährdungen aufgrund von Fehlern in der Software;
- Gefährdungen durch frei schwingende Lasten.
Für die Umrüstung in eine Zweiwege Maschine wird davon ausgegangen, dass ein EU Straßen zugelassenes Basisfahrzeug ein akzeptiertes Sicherheitsniveau für seine vorgesehenen Grundfunktionen bietet. Sofern in einem bestimmten Abschnitt nicht ausdrücklich etwas anderes festgelegt ist, wird dieser spezielle Aspekt in dieser Europäischen Norm nicht behandelt.
Andere Bau und Instandhaltungsmaschinen für den Einsatz auf Eisenbahngleisen werden in anderen Europäischen Normen behandelt, siehe Anhang F.
1.2 Gültigkeit dieses Dokuments
Dieses Dokument ist für alle Maschinen anzuwenden, die ein Jahr nach dem Veröffentlichungsdatum bei CEN dieses Dokuments bestellt werden.
Applications ferroviaires - Voie - Machines rail-route et équipements associés - Partie 1 : Exigences techniques pour le déplacement et le travail
1.1 Généralités
Le présent document traite des exigences techniques visant à réduire le plus possible les dangers ferroviaires spécifiques aux machines rail-route automotrices (désignées ci-après les « machines ») et aux équipements associés. Ces risques peuvent se manifester lors des opérations de mise en service, d'exploitation et de maintenance des machines, ces opérations étant réalisées conformément aux spécifications données par le fabricant ou son mandataire.
Ces risques sont normalement les mêmes, quel que soit l'écartement de la voie. Toutefois, des exigences supplémentaires peuvent s'appliquer pour le déplacement et le travail sur les infrastructures ferroviaires à voies larges ou étroites, sur les chemins de fer autres que ceux à adhérence rail/roue et sur les infrastructures souterraines.
Le présent document s'applique aussi aux machines et aux équipements associés qui, en configuration de travail, prennent partiellement appui sur le ballast ou sur la plate-forme. Ces machines sont capables d'accomplir des mouvements automoteurs indépendants sur la plate-forme.
Le présent document ne s'applique pas :
— aux exigences relatives à la qualité du travail et aux performances de la machine ;
— aux exigences spécifiques établies par l'opérateur de la machine en ce qui concerne l'emploi des machines et qui font l'objet de négociations entre le fabricant et le gestionnaire d'infrastructure ;
— aux modes travail et déplacement lorsque la machine n’est pas sur la voie ferrée ;
— aux machines distinctes montées provisoirement sur des machines ou équipements associés ;
— aux machines déraillables définies en 3.2 ;
— aux remorques définies en 3.3, y compris les remorques rail-route.
Les véhicules qui ne sont pas eux-mêmes guidés par la voie, mais qui ont des accessoires guidés par la voie ne sont pas considérés comme des machines rail-route.
Les prescriptions du présent document sont amendées et complétées par les prescriptions de l’EN 15746 4 pour les machines conçues et destinées à emprunter les réseaux ferroviaires urbains.
Le présent document n'entend pas non plus définir les exigences supplémentaires suivantes :
— mise en œuvre de la machine dans des conditions soumises à des règles particulières (par exemple, atmosphères potentiellement explosives) ;
— dangers dus à des causes naturelles (tremblement de terre, foudre, inondation, etc.) ;
— méthodes de travail ;
— exploitation de la machine dans des conditions de travail rigoureuses nécessitant des mesures particulières (en tunnels ou en tranchées, par exemple) ou dans des conditions d'environnement extrêmes (températures très froides ou très élevées, environnements corrosifs, tropicaux ou contaminants, forts champs magnétiques) ;
— dangers dus aux erreurs de logiciels ;
— dangers dus aux mouvements de charges librement suspendues susceptibles de se balancer.
Pour une machine rail-route, il est supposé qu'un véhicule-hôte autorisé à circuler sur le réseau routier au sein de l'Union européenne offrira un niveau de sécurité acceptable pour ses fonctions de base avant conversion. Sauf spécification contraire explicite dans un article particulier, cet aspect spécifique n'est pas traité dans la présente Norme européenne.
Les autres machines de construction et de maintenance de la voie empruntant également les voies ferrées sont couvertes par d'autres Normes européennes (voir Annexe F).
1.2 Validité du présent document
Le présent document s'applique à toutes les machines commandées un an ou plus après la date de publication CEN du présent document.

Overview
EN 15746-1:2020 - identical to EN 15746-1:2020 - defines the technical requirements for self‑propelled road‑rail machines and associated equipment used on railway track for travelling and working. Its purpose is to minimize railway‑specific hazards during commissioning, operation and maintenance when machines are used in accordance with the manufacturer's specification. The standard applies across track gauges (with additional gauge‑specific requirements where needed) and covers machines that may be partly supported on ballast or formation but are capable of independent self‑propelled ground movement.
This standard does not cover work quality/performance requirements, operator‑specific conditions that must be negotiated with infrastructure managers, non‑rail working, demountable modules, trailers (including road‑rail trailers), or vehicles that are not track‑guided. It is complemented by EN 15746‑4 where machines are intended for urban rail use. The standard applies to machines ordered one year after the CEN publication date.
Key topics and technical requirements
SIST EN 15746‑1:2021 addresses a comprehensive set of railway safety topics for road‑rail machines, including:
- Machine categorization and type approval - classification of machine types and implications for testing and approval.
- Clearances and travelling/working gauges - defining travelling gauge, working limits and lateral exceedance on curves.
- Interaction with infrastructure - wheel loads, stresses induced into rails, ballast and formation loads.
- Safety against derailment - requirements and dynamic testing adapted to machine speed categories.
- Stability and overturning prevention - static and dynamic stability proofs, load‑moment control and display.
- Running gear and suspension - wheel arrangements, wheel profiles, rail wheel suspension systems.
- Braking and towing devices - braking performance, emergency recovery and towing provisions.
- Driving/working cabs, controls, visibility and audibility - operator ergonomics, lighting, marker lamps and warning systems.
- Electrical/electromagnetic requirements - equipotential bonding, antennae/pantograph considerations and EMC.
- Failure recovery, on/off tracking and setting up - emergency devices, turntable use and packing away.
- Special equipment - MEWPs, excavators used as MEWPs and related provisions.
(The standard excludes hazards from extreme natural events, explosive atmospheres, software errors, and suspended swinging loads.)
Practical applications and users
This standard is essential for:
- Manufacturers of road‑rail machines converting road vehicles for rail use,
- Infrastructure Managers specifying safe machine use on track,
- Safety engineers and certifying bodies carrying out type approval and conformity assessment,
- Procurement teams ensuring purchased equipment complies with railway safety requirements,
- Maintenance and operations personnel who apply procedures consistent with design limits.
Using SIST EN 15746‑1:2021 helps reduce derailment, overturning and infrastructure damage risks and supports regulatory compliance for track maintenance fleets.

Introduction
This European Standard was prepared to meet the essential requirements of EU Directives to facilitate
an open market for goods and services.
This document is the first of a series of four parts of the European Standard: Railway applications —
Track — Road-rail machines and associated equipment, dealing with railway specific risks of the road-
rail machines when running, travelling and working on railway infrastructures:
— Part 1 covers the technical requirements for the machines in travelling and working modes, and is
applicable for all machines.
— 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 3 covers the essential requirements for the machines that have a running mode and run on
tracks within the scope of the Railway Directive 2007/58/EC; this is a document harmonized with
the Railway Interoperability Directive 2008/57/EC and its associated Technical Specifications for
Interoperability (TSI).
— Part 4 covers the technical requirements for the machines that have a running mode on urban rail
and/or for machines intended to have running, travelling and/or working mode on urban rail.
Part 1 defines requirements for approval of the machine for use on the railway. Depending on the
decision of the Infrastructure Manager or National rules the assessment of conformance could be by the
Infrastructure Manager concerned, by a third party assessor or declaration of conformity by the
manufacturer.
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.
Part 3 defines requirements for running on the European railway network. Assessment of conformity is
by a notified body as prescribed in the Railway Interoperability Directive.
Part 4 defines requirements for approval of the machine for use on urban rail. Depending on the
decision of the manager of the network or National rules the assessment of conformance could be by
the Urban Rail Manager concerned, by a third party assessor or declaration of conformity by the
manufacturer.
The risks 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
European Standard. Where necessary, references are made to appropriate standards of this type.
1 Scope
1.1 General
This document deals with the technical requirements to minimize the specific railway hazards of self-
propelled road-rail machines – henceforward referred to as machines – and associated equipment,
which can arise during the commissioning, operation and maintenance of the machines when carried
out in accordance with the specification given by the manufacturer or his authorized representative.
These risks are normally common regardless of the track gauge. However, additional requirements can
apply for travelling and working on infrastructures with narrow gauge or broad gauge lines, railways
utilizing other than adhesion between the rail and rail wheels and underground infrastructures.
This document is also applicable for machines and associated equipment that in working configuration
are partly supported on the ballast or the formation. Such machines are capable of independent self-
propelled movement on the ground.
This document does not apply to the following:
— the requirements for quality of the work or performance of the machine;
— the specific requirements established by the machine operator for the use of machines, which will
be the subject of negotiation between the manufacturer and the Infrastructure Manager;
— moving and working while not on rails;
— separate machines temporarily mounted on machines and associated equipment;
— demountable machines as defined in 3.2;
— trailers as defined in 3.3, including road-rail trailers.
Vehicles which are not track-guided themselves but have attachments that are track-guided are not
road-rail machines.
The requirements within this document are amended and added to by the requirements in EN 15746-4
for machines designed and intended to use urban rail.
This document does not establish the 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 such as: freezing temperatures, high temperatures,
corrosive environments, tropical environments, contaminating environments, strong magnetic
fields;
— hazards due to errors in software;
— hazards occurring when used to handle suspended loads which may swing freely.
For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted
safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a
particular clause this specific aspect is not dealt with in this European Standard.
Other track construction and maintenance machines used on railway tracks are dealt with in other
European Standards, see Annex F.
1.2 Validity of this document
This document applies to all machines which are ordered one year after the publication date by CEN of
this document.

Frequently Asked Questions
EN 15746-1:2020 is a standard published by the European Committee for Standardization (CEN). Its full title is "Railway applications - Track - Road-rail machines and associated equipment - Part 1: Technical requirements for travelling and working". This standard covers: 1.1 General This document deals with the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, operation and maintenance of the machines when carried out in accordance with the specification given by the manufacturer or his authorized representative. These risks are normally common regardless of the track gauge. However, additional requirements can apply for travelling and working on infrastructures with narrow gauge or broad gauge lines, railways utilizing other than adhesion between the rail and rail wheels and underground infrastructures. This document is also applicable for machines and associated equipment that in working configuration are partly supported on the ballast or the formation. Such machines are capable of independent self-propelled movement on the ground. This document does not apply to the following: - the requirements for quality of the work or performance of the machine; - the specific requirements established by the machine operator for the use of machines, which will be the subject of negotiation between the manufacturer and the Infrastructure Manager; - moving and working while not on rails; - separate machines temporarily mounted on machines and associated equipment; - demountable machines as defined in 3.2; - trailers as defined in 3.3, including road-rail trailers. Vehicles which are not track-guided themselves but have attachments that are track-guided are not road-rail machines. The requirements within this document are amended and added to by the requirements in EN 15746 4 for machines designed and intended to use urban rail. This document does not establish the 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 such as: freezing temperatures, high temperatures, corrosive environments, tropical environments, contaminating environments, strong magnetic fields; - hazards due to errors in software; - hazards occurring when used to handle suspended loads which may swing freely. For a road-rail machine it is assumed that an EU road permissible host vehicle will offer an accepted safety level for its designed basic functions before conversion. Unless explicitly stated otherwise in a particular clause this specific aspect is not dealt with in this European Standard. Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex F. 1.2 Validity of this document This document applies to all machines which are ordered one year after the publication date by CEN of this document.

Die Norm EN 15746-1:2020 behandelt die technischen Anforderungen zur Minimierung spezifischer Bahnrisiken von selbstfahrenden Straßenschienenmaschinen und zugehörigen Geräten. Diese Norm ist von zentraler Bedeutung für die Sicherheit beim Betrieb, der Inbetriebnahme und der Wartung dieser Maschinen. Ein hervorzuhebender Aspekt der Norm ist ihr umfassender Geltungsbereich, der sich nicht nur auf Maschinen mit Standardspurweite beschränkt, sondern auch spezifische Anforderungen für enge und breite Spurweiten sowie für andere Betriebsarten, wie z.B. unterirdische Infrastrukturen, berücksichtigt. Dies steigert die Relevanz der Norm erheblich, da sie für verschiedene Einsatzszenarien anwendbar ist. Darüber hinaus wird bei der Definition von Maschinen darauf geachtet, dass auch solche Geräte, die teilweise auf Schotter oder dem Untergrund unterstützt werden, in den Anwendungsbereich fallen. Dies zeigt die Flexibilität und den praktischen Nutzen der Norm im Bereich der Bahntechnologie. Ein weiterer Stärkenaspekt ist die klare Abgrenzung der nicht abgedeckten Bereiche, die es den Benutzern ermöglicht, Missverständnisse zu vermeiden. So sind beispielsweise Anforderungen zur Arbeitsqualität oder spezifische Betreiberanforderungen explizit ausgeschlossen. Dies schafft Transparenz und ermöglicht es Produzenten und Infrastruktur-Managern, ihre Vereinbarungen gezielt zu treffen. Die Norm berücksichtigt auch die Sicherheit bei der Benutzung der Maschinen in verschiedenen Umgebungen, allerdings nicht speziell im Hinblick auf außergewöhnliche Betriebsbedingungen, was die Norm im Hinblick auf ihre Grenzen definiert. Die Anwendbarkeit auf Maschinen, die nicht schienengeführt sind, sowie die gezielte Ausklammerung von Anforderungen für Spezialfälle, wie z.B. explosionsgefährdete Atmosphären, zeigen das Engagement der Norm, sich auf die sicherheitsrelevanten Aspekte zu konzentrieren, die für den alltäglichen Betrieb entscheidend sind. Zusammenfassend lässt sich sagen, dass die Norm EN 15746-1:2020 durch ihre umfassenden technischen Anforderungen, die klare Geltungsbereichsdefinition und die Berücksichtigung verschiedener Betriebsbedingungen eine wichtige Ressource für Hersteller, Betreiber und Infrastrukturmanager darstellt, um die Sicherheit und Effizienz von selbstfahrenden Straßenschienenmaschinen zu gewährleisten.
