Railway applications - Infrastructure - Demountable machines, trailers and associated equipment - Part 2: General safety requirements

This document specifies the general safety requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as ‘machines, for use when travelling and working on railway track.
NOTE   Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines.
This document specifies the requirements to deal with the common hazards presented by their use on the railway 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.
These machines will not run on railway lines open to normal traffic.
NOTE   Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020.
This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.
The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s).
This document does not apply to the following:
-   requirements for quality of the work or performance of the machine;
-   use of separate equipment temporarily mounted on machines;
-   machines that utilize external power supplies such as the overhead contact line system for traction purposes or as a power source;
-   hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;
-   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. corrosive environments, contaminating environments, strong magnetic fields;

EN 15955, Railway applications — Track — Demountable machines, trailers and associated equipment, is
currently composed with the following parts:
— Part 1: Technical requirements for travelling and working;
— Part 2: General safety requirements.

Introduction
The machinery concerned and the extent to which hazards, hazardous situations and events are covered
are indicated in the scope of this document.
This document is the second of a series of two parts of the European standard: Railway applications —
Track — Demountable machines, trailers and associated equipment, dealing with railway specific risks of
the demountable machines and trailers when travelling and working on railway infrastructures:
— Part 1 covers the safety and technical requirements for the machines in travelling and working
modes, and is applicable for all machines, including those in operation on urban rail;
— 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 1 defines requirements for approval of the machine for use on the railway. Depending on the decision
of the Infrastructure Manager, Urban Rail Manager or the requirements in National rules the assessment
of conformance could be undertaken by the Infrastructure/Urban Rail Manager concerned, by a third
party assessor or by the manufacturer as a declaration of conformity.
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.
This document was prepared to meet the basic requirements of EU Directives to facilitate an open market
for goods and services.
This document deals with railway specific risks of the demountable machines and trailers as defined in
3.1, 3.2 and 3.3 when travelling and working on railway infrastructures.
This document is a type C standard as stated in EN ISO 12100:2010.
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 in accordance with the provisions of this type C standard.
The hazards 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
document. Where necessary, references are made to appropriate standards of this type.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);

1 Scope
This document specifies the general safety requirements for demountable machines and trailers,
including road-rail trailers – henceforward referred to as ‘machines, for use when travelling and working
on railway track.
NOTE Trailers, including road-rail trailers, are considered as machines because they are moved along the track
by powered machines.
This document specifies the requirements to deal with the common hazards presented by their use on
the railway 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.
These machines will not run on railway lines open to normal traffic.
NOTE Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other
European standards, see Technical Report CEN/TR 17498:2020.
This document is also applicable to machines and associated equipment that in working mode are partly
supported on the ballast or the formation.
The requirements in this document are based on the assumption that the machines are used, operated
and maintained by skilled person(s).
This document does not apply to the following:
— requirements for quality of the work or performance of the machine;
— use of separate equipment temporarily mounted on machines;
— machines that utilize external power supplies such as the overhead contact line system for traction
purposes or as a power source;
— hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;
— 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. corrosive environments,
contaminating environments, strong magnetic fields;
— hazards occurring when used to handle suspended loads which may swing freely.
