CEN/TC 256/SC 1/WG 5 - Track construction and maintenance machines

This document specifies the significant hazards, hazardous situations and events, common to self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, arising due to the adaptation for their use on railway networks and urban rail networks. These machines are intended for construction, maintenance and inspection of the railway infrastructure, shunting and emergency rescue vehicles, when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer; see Clause 4.
This document deals with the common hazards during assembly and installation, commissioning, travelling on and off track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines.
NOTE   Specific measures for exceptional circumstances are not dealt with in this document. They can be subject to negotiation between manufacturer and the machine operator.
The common hazards dealt with include the general hazards presented by the machines, also the hazards presented by the following specific machine functions:
a)   excavation;
b)   ballast tamping, ballast cleaning, ballast regulating, ballast consolidating;
c)   track construction, renewal, maintenance and repair;

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.

These hazards can arise during the commissioning, the operation and the maintenance of machines when carried out in accordance with the specification given by the manufacturer or his authorized representative. Where a machine is designed and intended for use on mainline and urban rail, the machine will comply with the most onerous conditions of FprEN 15746-1 and FprEN 15746-4. In all cases the machine will comply with the requirements set out in FprEN 15746-2.
The requirements in this document amend those in FprEN 15746-1 as required for the use of the machine on urban railways.
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 Urban Rail Manager;

Other track construction and maintenance machines used on railway tracks are dealt with in other European Standards, see Annex B.
1.2   Scope of urban rail
Urban rail systems cover Urban Guided Transport systems (UGT) and might include other rail systems excluded from the scope of the Interoperability Directive 2008/57/EC (Article 1.3 (a) and (b)).
Urban Guided Transport systems (UGT), which cover metro, tram and light rail, are defined as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic.
Categories of urban rail systems include:
-   (I) Metros: UGT systems operated on their own right of way and segregated from general road and pedestrian traffic. They are consequently designed for operations in tunnel, viaducts or on surface level but with physical separation in such a way that inadvertent access is not possible. In different parts of the world, Metro systems are also known as the underground, the subway or the tube. Rail systems with specific construction issues operating on a segregated guideway (e.g. monorail, rack railways) are also treated as Metros as long as they are designated as part of the urban public transport network.
-   (II) Trams: UGT systems not segregated from general road and pedestrian traffic, which share their right of way with general road and/or pedestrian traffic and are therefore embedded in their relevant national road traffic legislation (highway codes and specific adaptations).

The running mode is an option designed by the manufacturer which permits the use of the machine on a specified railway infrastructure without the need for special operational rules.
NOTE 1   The use of special track safety equipment (i.e. part of automatic train protection systems) does not necessarily mean that the machine has a running mode; some Infrastructure Managers use such equipment as means of protection for machines in travelling and/or working modes.
NOTE 2   This document is written for 1 435 mm nominal track gauge; special requirements can apply for running on infrastructures with narrow gauge or broad gauge lines.
Urban rail and railways utilizing other than adhesion between the rail and wheels are not included in this document.
This document does not apply to the following:
-   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;
-   travelling and working both on and off rails;
-   running on urban rail.
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.

This European Standard specifies the common hazards, in normal circumstances, during running, assembly and installation, commissioning, use (including setting, programming, and process changeover), operation, cleaning, fault finding, maintenance and de-commissioning of the machines. Additional safety measures can be required by exceptional circumstances, such as extreme ambient temperatures (less than - 20 °C or greater than + 40 °C), highly corrosive or contaminating environment; e.g. due to the presence of chemicals, and potentially explosive atmospheres. Air pressure caused by the passing of high-speed trains at more than 190 km/h is also not dealt with.
NOTE 1 Specific measures for exceptional circumstances are not dealt with in this European Standard. The specific measures for exceptional circumstances introduced by a railway infrastructure manager and requirements introduced by the manufacturer and/or machine operator as referred to in the scope are not dealt with in this European Standard. When such additional measures are necessary, they should be agreed between the manufacturer and the machine operator. The manufacturer will be responsible for compliance with the Directive(s) concerned independent of this European Standard for additional hazards created by any additional or alternative requirements.
NOTE 2 This European Standard deals only with the additional hazards from the adaptation of a machine for its use on rail. Other standards specific to the particular machine as far as available will need to be used in addition to this European Standard to give the complete requirements.

1.1   General
This European Standard specifies the technical requirements to minimise 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. These machines are not designed or intended to operate signalling and control systems and are only designed and intended to work and run under special operating conditions specifically designated by the infrastructure manager. Other machines are dealt with in other European Standards; see Annex D.
This part of EN 15955 deals with the technical railway requirements; Part 2 deals with the requirements for the machine to be declared conformant by the manufacturer, except in the case of machines classified in Annex 4 of the Machinery Directive (2006/42/EC) which requires conformity check in conjunction with a notified body.
These demountable machines 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.
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 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;

-   hazards due to errors in software;
-   hazards occurring when used to handle suspended loads which may swing freely.
The intended use of these machines may have operational parameters specified by each infrastructure manager, e.g. 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. These machines 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 machines, which are ordered one year after the publication date by CEN of this standard.

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.

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:

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.

1.1   General
This European Standard 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, the operation and the maintenance of machines when carried out in accordance with the specification given by the manufacturer or his authorized representative when designed and intended for running, travelling and/or working on urban railways only. Where a machine is designed and intended for use on mainline and urban rail the most onerous conditions of prEN 15746 1 and prEN 15746 4 will need to be complied with.
The requirements in this standard amend those in prEN 15746 1 as required for the use of the machine on urban railways.
This European Standard 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 controller of an urban railway;
-   moving and working while not on rails;
-   separate machines temporarily mounted on machines and associated equipment.
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;
-   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 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 B.
1.2   Scope of urban rail
Urban rail systems cover both Urban Guided Transport systems (UGT) and other rail systems which might be excluded from the scope of the Interoperability Directive 2008/57/EC (Article 1.3 (a) and (b)).
Urban Guided Transport systems (UGT), which cover metro, tram and light rail, are defined as public transport systems permanently guided at least by one rail, intended for the operation of local, urban and suburban passenger services with self-propelled vehicles and operated either segregated or not from general road and pedestrian traffic.
Categories of urban rail systems include:
-   (I) Metros: UGT systems operated on their own right of way and segregated from general road and pedestrian traffic. They are consequently designed for operations in tunnel, viaducts or on surface level but with physical separation in such a way that inadvertent access is not possible. In different parts of the world, Metro systems are also known as the underground, the subway or the tube. Rail systems with specific construction issues operating on a segregated guideway (e.g. monorail, rack railways) are also treated as Metros as long as they are designated as part of the urban public transport network.
-   (II) Trams: UGT systems not segregated from general road and pedestrian traffic, which share their right of way with general road and/or pedestrian traffic and are therefore embedded in their relevant national road traffic legislation (highway codes and specific adaptations).

A manufacturer should carry out an appropriate risk assessment for the complete machine. Irrespective of whether a harmonized standard exists for the machine in road configuration, this should identify any additional hazards arising from the particular application of the chassis and the protective measures required to adequately deal with them.
This European Standard does not deal with:
1)   requirements with regard to the quality of work and the performance of the machine;
2)   machines that utilize the catenary for traction purposes;
3)   specific requirements established by a railway infrastructure manager;
4)   negotiations between the manufacturer and the machine operator for additional or alternative requirements;

Air pressure caused by the passing of high-speed trains at more than 190 km/h is also not dealt with.
NOTE 1   Specific measures for exceptional circumstances are not dealt with in this European Standard. The specific measures for exceptional circumstances introduced by a railway infrastructure manager and requirements introduced by the manufacturer and/or machine operator as referred to in the scope are not dealt with in this European Standard. When such additional measures are necessary, they should be agreed between the manufacturer and the machine operator. The manufacturer will be responsible for compliance with the Directive(s) concerned independent of this European Standard for additional hazards created by any additional or alternative requirements.
NOTE 2   This European Standard deals only with the additional hazards from the adaptation of a machine for its use on rail. Other standards specific to the particular machine as far as available will need to be used in addition to this European Standard to give the complete requirements.
The common hazards specified include the general hazards presented by the machines, and also the hazards presented by the following specific machine functions, common to two or more machine types:
-   ballast excavation, ballast cleaning, ballast regulating, ballast consolidating;
-   tamping;
-   track renewal;
-   craning;
-   maintenance of the components of the infrastructure;
during commissioning, use, maintenance and servicing.
This European Standard does not deal comprehensively with specific machine functions other than the common functions listed in the previous paragraph, or with all possible hazards presented by complete machines or by the combination of functions.
NOTE 3   For such specific functions or hazards, the use of specific European Standards is recommended.
This European Standard does not deal with:
-   requirements with regard to the quality of work and the performance of the machine;
-   machines that utilise the catenary for traction purposes;
-   specific requirements introduced by a railway infrastructure manager;
-   additional or alternative requirements introduced by the manufacturer and/or operator.

This European Standard applies to discs designed to be fitted to rail vehicles used on the main national networks, urban networks, underground railways, trams, private networks (regional railways, company railways, etc.).
This European Standard comprises a basic test of disc performance. The disc is tested for energy dissipation, power conversion and ventilation characteristics as well as mechanical integrity. The disc and pad interaction couple, which is used as a reference, are defined. The classification qualifies a brake disc with the defined brake pads by dynamometer tests for type validation by in-service experience for up to one year without additional tests in the defined application class. It does not give rules for the application and the brake performance in specific trains. For this purpose additional tests may be necessary.
The classes may give a recommendation for a preliminary selection of the required brake equipment to the vehicle designer.
Except for the frictional performances, the tests defined in this standard are type test according EN 14535 1 and EN 14535-2.
