Foreword
This document (prEN 15955-2:2009) 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.
For relationship with EC Directive(s), see informative Annex ZA and ZB, which are integral parts of this
document.
“Railway applications – Track – Demountable machines and associated equipment” consists of the following
parts:
Part 1: Technical requirements for running and working;
Part 2: General safety requirements.

Introduction
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
This European Standard deals with the significant hazards, hazardous situations and events, common to
demountable machines, as defined in prEN xxxzz-1, intended for construction, maintenance inspection of the
railway infrastructure, shunting and emergency rescue vehicles, 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 machines.
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 machines, and also 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
during commissioning, use, maintenance and servicing.

This European Standard applies to self propelled machines 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 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.
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 established by a railway infrastructure manager;
 negotiations between the manufacturer and the machine operator for additional or alternative
requirements;
 hazards due to air pressure caused by the passing of high-speed trains at more than 190 km/h;
 requirements which could be necessary in case of use in extreme conditions, such as:
 extreme ambient temperatures (tropical or polar);
 highly corrosive or contaminating environment, e.g. due to the presence of chemicals;
 potentially explosive atmospheres.
This European Standard applies to all machines that are ordered one year after the publication date by CEN
of this standard.
