NOTE In this document, there are some entries where more than one term is listed in the header (e.g. sleeper, tie, cross tie in 3.2.3). In such cases, the first term is the preferred term, generally used in the ISO 22074 series of standards. The other terms are also in common use in the railway industry and are considered to be synonymous (admitted terms).

This European Standard deals with mechanical rail joints for flat bottom rails 46 kg/m and over. The scope of this standard is: to
establish requirements for insulated and non-insulated rail joints, for stressed rail (continuous welded rail, CWR) and unstressed rail (jointed track); to define mechanical and electrical requirements for type approval and for acceptance of insulated rail joints which are manufactured in a factory (prefab construction) as well as assembled onsite (site construction). This standard specifies the minimum requirements. Special applications as for instance tram systems may require different demands in certain paragraphs and should be agreed between customer and supplier. The scope also excludes expansion joints (it is covered in EN 13232-8), and special joints in switch constructions.

This European Standard defines the activities related to work on or near the railway track and the associated competence profiles of persons who carry out these activities and defines procedures for assessing the competence.

This European Standard provides requirements and measures to deal with the significant and specific railway risks during works on or in proximity of the track and with common principles for the protection of fixed and mobile work sites with trains and/or machines circulating on the working track and trains circulating on the adjacent track(s). Railway risks and protection measures for access and egress to/from the work site are considered in the same way as railway risks and protection measures for work itself.
This European Standard is applicable to all operations related to work activities on rail guided systems. Infrastructure of metro, tram and other light rail systems is excluded from the scope ).
The following specific railway risks are taken into consideration:
—   Risk 1: Personnel being struck by a train or injured due to wind drag  from a train on open working track (safety of the worker);
NOTE 1   Risk 1 includes injuring of a worker by machines, material or equipment being struck by a train on the working track.

NOTE 2   Risk 5 includes hazards caused by pantographs of passing trains.
This European Standard also provides requirements to the process of installing basic preventive measures when planning new infrastructure or installing corrective measures when adapting existing infrastructure.
This European Standard may be extended to third parties when it is considered appropriate and reasonable by the infrastructure manager, if one or more of the five significant risks described inside this standard, arise as a result of their activities in proximity of the track.

1.1   General
This document specifies the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines - henceforward referred to as machines - and associated equipment, intended for use on urban rail. 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;
-   moving and working while not on rails;
-   separate machines temporarily mounted on machines and associated equipment.
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. 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 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).
(...)

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;
d)   lifting;
e)   overhead contact line system renewal / maintenance;
f)   maintenance of the components of the infrastructure;
g)   inspection and measurement of the components of the infrastructure;
h)   working in tunnels;
i)   shunting;
j)   vegetation control;
k)   emergency rescue and recovery;
during commissioning, use, maintenance and servicing.
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 document.
This document does not deal with:
1)   requirements with regard to the quality of work and the performance of the machine;
2)   machines that utilize the contact line system for traction purposes;
3)   specific requirements established by a railway Infrastructure Manager or Urban Rail Manager;
4)   negotiations between the manufacturer and the machine operator for additional or alternative requirements;
5)   requirements for use and travel of the machine on public highway;
6)   hazards due to air pressure caused by the passing of high-speed trains at more than 190 km/h;
7)   requirements which could be necessary in case of use in extreme conditions, such as extreme ambient temperatures (tropical or polar); see 5.30;
8)   highly corrosive or contaminating environment, e.g. due to the presence of chemicals;

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.

1.1   General
This document deals with the technical requirements to minimize the specific railway hazards of self-propelled road-rail machines, as defined in EN 15746 1:2020, 3.1, henceforward referred to as machines, when designed and intended for running on European railways within the scope of European Directive 2007/58/EC.
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.
1.2   Validity of this document
This document applies to all machines which are within the scope of the Commission Regulation (EU) No 1302/2014 for locomotives and passenger rolling stock.

This document specifies the defect management system the infrastructure manager uses to control the risk of severe accidents due to degradation of internal or surface defects on rails complying with EN 13674-1, EN 13674-2, EN 13674-4 and EN 15689:2009 (excluding grooved rails EN 14811 - which need alternative systems).

This European Standard characterizes the quality of track geometry based on parameters defined in EN 13848 1 and specifies the different track geometry classes which should be considered.
This European Standard covers the following topics:
- description of track geometry quality;
- classification of track quality according to track geometry parameters;
- considerations on how this classification can be used;
- this European Standard applies to high-speed and conventional lines of 1 435 mm and wider gauge;
- this European Standard forms an integral part of EN 13848 series.

This document specifies the minimum requirements for track geometry measuring principles and track geometry measuring systems in order to produce comparable results when measuring the same track. It applies to all measuring systems, attended or unattended, fitted on any vehicle, except those systems defined in EN 13848 3 and EN 13848 4. Only systems put into service after the standard comes into force are concerned.
This document does not define the requirements for vehicle acceptance.
This document does not apply to measuring systems dedicated to Urban Rail Systems.

This document defines the technical requirements and measurements for the acceptance of works for longitudinal and/or transverse reprofiling of railway rail heads in plain line, switches and crossings and expansion devices.
This document applies to Vignole rails of 46 kg/m and above according to EN 13674-1.

This document is applicable to under ballast mats used in ballasted track and defines the test procedures and their evaluation criteria.
This document provides particular information in the following areas:
-   test methods, test arrangements and evaluation criteria of under ballast mats;
-   data supplied by the purchaser and by the supplier;
-   definition of general process of design approval tests;
-   definition of routine tests.
