Railway applications - Track - Trailers and associated equipment - Part 1: Technical requirements for running and working

Railway applications - Track - Trailers and associated equipment - Part 1: Technical requirements for running and working

This European Standard deals with the technical requirements to minimize the specific railway hazards of trailers and associated equipment, which can arise during the commissioning, the operation and the maintenance of trailers when carried out in accordance with the specification given by the manufacturer or his authorized representative. This European Standards applies to trailers that are not intended to operate signalling and control systems. Other similar machines are dealt with in other European Standards,
see Annex G.
Note   Machines not intended for operating signalling and control systems are only permitted to run under special conditions and within areas specifically designated by the infrastructure manager.
Part 1 of this European Standard deals with requirements for approval of the trailer by an authorized body, part 2 deals with requirements for the trailer to be declared conformant by the manufacturer, except in the case of trailers classified in Annex 4 of the Machinery Directive which require conformity check in conjunction with a notified body.
Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilizing other than adhesion between the rail and rail wheels, and underground infrastructures.
This European Standard is also applicable for trailers and associated equipment that in working configuration are partly supported on the ballast or the formation.
Where two or more trailers are used together to transport loads in a fixed formation, e.g. where a metal container is fixed to two small trailers, the whole system shall be treated as a trailer and comply with the requirements of this European Standard.

Bahnanwendungen - Oberbau - Anhänger und zugehörige Ausstattung - Teil 1: Technische Anforderungen an das Fahren und den Arbeitseinsatz

Diese Europäische Norm legt die technischen Anforderungen zur Minimierung eisenbahnspezifischer
Gefahren von Anhängern und zugehöriger Ausstattung fest, die bei der Inbetriebnahme, dem Betrieb und der
Instandhaltung von Anhängern, den Anweisungen des Herstellers oder seinem berechtigten Vertreter folgend,
entstehen können. Diese Europäische Norm gilt für Anhänger, die nicht für den Betrieb von Signal- und
Steuerungssysteme vorgesehen sind. Ähnliche Maschinen werden in anderen Europäischen Normen
behandelt, siehe Anhang G.
ANMERKUNG Maschinen, die nicht für den Betrieb von Signal- und Steuerungssystemen vorgesehen sind, dürfen
nur unter speziellen Bedingungen fahren und nur in Streckenabschnitten, die gesondert vom Infrastrukturunternehmer
bestimmt sind.
Teil 1 dieser Europäischen Norm behandelt die Anforderungen für die Prüfung der Anhänger durch eine
autorisierte Stelle, Teil 2 behandelt die Anforderungen an die Anhänger für die Konformität, die der Hersteller
bestätigt, mit Ausnahme von Anhängern, die nach der Maschinenrichtlinie, Anhang 4 klassifiziert sind und
eine Konformitätsprüfung in Verbindung mit einer notifizierten Stelle benötigen.
Für das Fahren auf Infrastrukturen mit schmalen Spurweiten oder auf Breitspurstrecken, Straßenbahnlinien,
von Eisenbahnen, die eine andere Haftreibung zwischen Schiene und Rad nutzen, und Infrastrukturen im
Untergrund können zusätzliche Anforderungen bestehen.
Diese Europäische Norm gilt auch für Anhänger und zugehörige Ausrüstungen, die sich in Arbeitstellung
teilweise auf dem Schotter oder dem Untergrund (Planum) abstützen.
Wenn zwei oder mehrere Anhänger für das Fahren von Lasten in einer bestimmten Anordnung eingesetzt
werden, z. B. wenn ein Eisencontainer an zwei schmalen Anhängern befestigt ist, muss das ganze System als
ein Anhänger betrachtet werden und den Anforderungen dieser Europäischen Norm entsprechen.

Railway applications - Track - Trailers and associated equipment - Part 1: Technical requirements for running and working
SIST EN 15954-1:2013

1.1   General
This European Standard specifies the technical requirements to minimise the specific railway hazards of trailers and associated equipment, which can arise during the commissioning, the operation and the maintenance of trailers when carried out in accordance with the specification given by the manufacturer or his authorised representative. This European Standard applies to trailers that are not intended to interact with operating signalling and control systems. Other machines are dealt with in other European Standards; see Annex E.
These trailers are not designed or intended for operating signalling and control systems and are only intended to work and run under special operating conditions specifically designated by the infrastructure manager.
These trailers are not intended to be vehicles as defined in the Interoperability Directive and are not permitted to run on the railway lines open to normal traffic. If this is required, they will need to be authorised or placed into service as set out in the Interoperability Directive 2008/57/EC.
Part 1 of this European Standard deals with the technical railway requirements; Part 2 deals with requirements for the trailer to be declared conformant by the manufacturer, except in the case of trailers classified in Annex 4 of the Machinery Directive 2006/42/EC which require conformity check in conjunction with a notified body.
Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilising other than adhesion between the rail and rail wheels, and underground infrastructures.
This European Standard is also applicable to trailers and associated equipment that in working configuration are partly supported on the ballast or the formation.
Where two or more trailers are used together to transport loads in a fixed formation, e.g. where a metal container is fixed to two small trailers, the whole system is treated as a trailer for the purposes of compliance with the requirements of this European Standard.
This European Standard does not apply to the following:
-   requirements for quality of the work or performance of the trailer;
-   specific requirements established by the railway infrastructure operator for the use of trailers, which will be the subject of negotiation between the manufacturer and the operator;
-   separate machines temporarily mounted on the trailer.
This European Standard 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, etc;
-   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 environment, contaminating environments, strong magnetic fields;
-   hazards due to errors in software;
-   hazards occurring when used to handle suspended loads which may swing freely.
The intended use of these trailers may have operational parameters specified by each infrastructure manager; for example the maximum speed allowed for these trailers is likely to be limited by the infrastructure manager
- compliance with the clauses of this standard does not confer permission for trailers to travel at this speed. These trailers will not be allowed on a track open to normal railway traffic.
1.2   Validity of this European Standard
This European Standard applies to all trailers, which are ordered one year after the publication date by CEN of this standard.

oSIST prEN 15955:2020

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.

Railway applications - Track - Trailers and associated equipment - Part 2: General safety requirements
oSIST prEN 15954-2:2009

This European Standard deals with the significant hazards, hazardous situations and events, common to trailers, as defined in the scope of prEN xxxyy-1:2009, intended for construction, maintenance and/or inspection of the railway infrastructure, emergency rescue and recovery, when they are used as intended by the manufacturer, see clause 4. The manufacturer shall give warning of the risks concerning the conditions of misuse which are reasonably foreseeable.
This European Standard deals with the common hazards during transport, assembly and installation, commissioning, running on track, use (including setting, programming, and process changeover), operation, cleaning, fault finding, maintenance and de-commissioning of the trailers.
NOTE   Specific measures for exceptional circumstances are not dealt with in this European Standard. They can be subject of negotiation between manufacturer and the operator.
The common hazards dealt with include the general hazards presented by the trailers, and also the hazards presented by the following specific trailer functions:
-   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;
   emergency rescue and recovery
during commissioning, use, maintenance and servicing.
This European Standard applies to trailers that are not intended to operate signalling and control systems. Other similar machines are dealt with in other European Standards, see Annex D.
It is assumed that a finished standard automotive chassis used as a host for a road-rail trailer will offer an acceptable safety level for its designed functions before conversion. This specific aspect is not dealt with in this European Standard.

Railway applications - Track - Demountable machines and associated equipment - Part 1: Technical requirements for running and working
oSIST prEN 15955-1:2022

This European Standard deals with the technical requirements to minimize the specific railway hazards of self propelled demountable machines - henceforward referred to as machines - and associated equipment, which can arise during the commissioning, the operation and the maintenance of these machines when carried out in accordance with the specification given by the manufacturer or his authorised representative. This European Standard applies to machines that are not intended to operate signalling and control systems. Other similar machines are dealt with in other European Standards, see Annex F.
NOTE   Machines not intended for operating signalling and control systems are only permitted to run under special conditions and within areas specifically designated by the infrastructure manager.
Part 1 of this standard deals with the requirements for approval of machines by an authorised body; part 2 deals with the requirements for the machine to be declared conformant by the manufacturer, except in the case of machines classified in Machinery Directive, Annex 4 which requires conformity check in conjunction with a notified body.
Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines of tramways, railways utilizing other than adhesion between the rail and rail wheels and underground infrastructures.
This European Standard is also applicable for machines and associated equipment that in working configuration are partly supported on the ballast or the formation.
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 between the manufacturer and the purchaser;
