European foreword
This document (prEN 15746-2:2015) has been prepared by Technical Committee CEN/TC 256 “Railway
applications”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 15746-2:2010+A1:2011.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association, and supports essential requirements of EU Directives.
For relationship with EU Directives, see informative Annexes ZA, ZB, or ZC, which are an integral part of
this document.
EN 15746, Railway applications — Track — Road-rail machines and associated equipment, is currently
composed with the following parts:
— Part 1: Technical requirements for running and working;
— Part 2: General safety requirements;
— Part 3: Technical requirements for running [currently at Enquiry stage];
— Part 4: Technical requirements for running, travelling and working on urban rail [currently at
Enquiry stage].
Introduction
This document is the second 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 working and travelling modes, and is
applicable for all machines.
— Part 2 covers the safety requirements for the machines in working and travelling modes; this is a
harmonized standard 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 harmonized standard 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 working and travelling modes 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 controller of the network or National rules the assessment of conformance could be by
the urban rail controller concerned, by a third party assessor or declaration of conformity by the
manufacturer.
This European Standard is a type C standard as stated in EN ISO 12100.
The machinery concerned and the extent to which hazards, hazardous situations and hazardous events
are covered are indicated in the scope of this European Standard.
When provisions of this type C standard are different from those which are stated in type B standards,
the provisions of this type C standard take precedence over the provisions of the other standards, for
machines that have been designed and built according to the provisions of this type C standard.
1 Scope
1.1 General
This European Standard specifies the significant hazards, hazardous situations and events, common to
self-propelled road-rail machines – henceforward referred to as machines – and attachments as defined
in prEN 15746-1:2015, 3.5 and 3.6, and arising due to the adaptation for their use on rail. 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 European Standard deals with the common hazards during running, 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 European Standard. 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, and 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) craning;
e) catenary renewal / maintenance;
f) maintenance of the components of the infrastructure;
g) inspection and measurement of the components of the infrastructure;
h) tunnel inspection / ventilation;
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 European Standard.
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;
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;
9) potentially explosive atmospheres.
Other special vehicles used on railway tracks are dealt with in other European Standards, see Annex E.
1.2 Validity of this European Standard
This European Standard applies to all machines that are ordered one year after the publication date by
CEN of this standard.
