Railway applications - Track - Trailers and associated equipment - Part 2: General safety requirements

This European Standard deals with the significant hazards, hazardous situations and events, common to trailers, as defined in the scope of prEN xxxyy-1:2009, intended for construction, maintenance and/or inspection of the railway infrastructure, emergency rescue and recovery, 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 trailers.
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 trailers, and also the hazards presented by the following specific trailer functions:
-   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;
   emergency rescue and recovery
during commissioning, use, maintenance and servicing.
This European Standard applies to trailers 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 road-rail trailer will offer an acceptable safety level for its designed functions before conversion. This specific aspect is not dealt with in this European Standard.

Overview

prEN 15954-2 - published as a CEN draft - sets out general safety requirements for railway trailers and associated equipment used on track. The standard addresses significant hazards common to trailers intended for construction, maintenance, inspection, emergency rescue and recovery of rail infrastructure when used as the manufacturer intends. It covers the full life-cycle: transport, assembly, installation, commissioning, running on track, operation (including setting/programming), cleaning, fault-finding, maintenance and de‑commissioning.

Keywords: prEN 15954-2, railway trailers, track trailers, general safety requirements, CEN standard, rail infrastructure safety.

Key topics and technical requirements

prEN 15954-2 provides a harmonised safety baseline and guidance on many technical areas without prescribing specific numeric performance values in this extract. Major topics include:

• Hazard identification - list of significant hazards and hazardous situations common to trailers.
• Access, egress and ergonomics - cab dimensions, walkways, seating, visibility and operator comfort.
• Stability and derailment prevention - stability checks, overturning prevention, lifeguards and rated capacity indicators.
• Braking and stopping - requirements for emergency stopping, holding on gradients, service and break‑away brakes.
• Controls, indicators and remote control - safe placement, inadvertent activation protection and start/stop systems.
• Electrical safety & EMC - wiring practices, batteries, catenary interface and electromagnetic compatibility.
• Fire, emissions, noise and vibration - risk assessment, fire-fighting equipment, emissions and operator exposure.
• Lifting, conveyors and elevating work platforms - additional measures for cranes, conveyors and lifting devices mounted on trailers.
• Verification and testing - methods such as visual exam, measurement, functional and load tests for conformity.
• Information for use - instruction handbook content, restrictions of use and mass/stability data.

Practical applications and users

This standard is essential for stakeholders involved in rail infrastructure equipment safety and procurement:

• Manufacturers and designers - to design compliant trailers and prepare instruction handbooks.
• Safety engineers and compliance teams - for risk assessments, conformity verification and documentation.
• Infrastructure managers and operators - to set operational limits, maintenance regimes and safe working procedures.
• Maintenance and inspection personnel - to follow verified maintenance and testing practices.
• Procurement and certification bodies - to specify safety requirements in contracts and acceptance testing.

Related standards

• prEN 15954-1 (referenced scope) and other CEN standards cover similar machines or specific functions (see Annex D). Machines intended to operate signalling and control systems are covered in other standards.

Using prEN 15954-2 helps harmonise safety across Europe, reduce operational risk, and provide clear verification and information-for-use requirements for railway trailers and associated equipment.

Foreword
This document (prEN 15954-2:2009) 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.
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 EC Directive(s).
For relationship with EC Directive(s), see informative Annex ZA and ZB, which are integral parts of this
document.
“Railway applications – Track – Trailers 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 trailers 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 trailers 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
trailers, as defined in the scope of prEN xxxyy-1:2009, intended for construction, maintenance and/or
inspection of the railway infrastructure, emergency rescue and recovery, 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 trailers.
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 trailers, and also the hazards
presented by the following specific trailer functions:
 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;
 emergency rescue and recovery
during commissioning, use, maintenance and servicing.

This European Standard applies to trailers 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 road-rail trailer 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 trailers;
 specific requirements established by a railway infrastructure manager;
 negotiations between the manufacturer and the trailer operator for additional or alternative requirements;
 requirements for use and running of the trailer on public highway;
 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 trailers that are ordered one year after the publication date by CEN of
this standard.

For the purposes of this document, the terms and definitions given in EN ISO 12100-1 and in
prEN xxxyy-1:2009 and the following apply.

3.1
rail configuration
state of a road-rail trailer when it is in place on the track ready to work or running along the track
NOTE Rail configuration does not include the transient state during getting on and off the track.
3.2
road configuration
state of a road-rail trailer when the trailer is on the ground, i.e. not on the track
NOTE It does not imply that the trailer is suitable for use on the public highway.
3.3
working place
working cabs, combined working and driving cabs, operators places situated outside cabs and places situated
at control or maintenance locations
3.4
operating brake
braking system to bring trailer (and any permitted towed load) to stand in specified distance during normal
operation and running of the trailer
3.5
parking brake
brake capable of operation and function without power from the trailer
3.6
rated capacity indicator (RCI)
device which gives, within specified tolerance limits, at least a continuous indication that the rated capacity is
exceeded
NOTE For rated capacity, see EN 12077-2.
4 List of significant hazards
Table A.1 shows all the significant hazards, hazardous situations and events, as far as they are dealt with in
this European Standard, identified by risk assessment as significant for this type of machinery and which
require action to eliminate or reduce the risk.
5 General safety requirements and/or measures
5.1 General
Trailers shall comply with the safety requirements and/or protective measures of this clause. In addition, the
trailer shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards,
which are not dealt with by this European Standard.
This standard formulates general/common requirements for the equipment in the scope of this standard,
therefore the manufacturer shall have to carry out a complete risk assessment for identifying the specific
hazards for the particular trailer and the corresponding measures (including the measures additional to those
of clauses 5 and 6 that may be required).
The function(s) of trailers which is (are) dealt with in another European Standard for machinery safety shall
comply with that standard as far as applicable and taking account of the additional requirements and
deviations of the present standard.
NOTE Relevant standards trailer functions are for example:
 For “road” earth moving machinery: Series EN 474;
 for cranes: EN 13001-1 ;
 for cranes on trucks: EN 12999;
 for mobile elevating work platforms: EN 280.
Where there is a conflict between the requirements of this European Standard and the other above-mentioned
European Standard(s), then this standard shall prevail.
When a choice is necessary for the application of type B standards referred to in this European Standard, e.g.
EN 60204-1, EN 982 and EN 983 the manufacturer shall carry out a risk assessment for making this choice.
If a road-rail trailer is constructed on the basis of a host vehicle this host vehicle shall comply with one of the
following:
 the European Standard for machinery safety relevant for that host vehicle (as far as not explicitly required
otherwise in specific clauses of this European Standard)
or
 this European Standard.
It is assumed that a finished automotive chassis or a chassis complying with the same rules, used as a host
for a road-rail trailer will offer an acceptable safety level for its designed functions before conversion. Unless
otherwise specified this specific aspect is not dealt with in this European Standard.
Where modifications are made to the original standard automotive chassis the manufacturer shall carry out an
appropriate risk assessment of the effects and consequences of the modifications on the whole trailer.

5.2 Access and egress to and from working places
5.2.1 Cabs
Except as shown below, where a trailer is fitted with driving cabs, working cabs and/or combined working and
driving cabs, access and egress shall be from both sides of the trailer or directly into the area between the
rails of the working track.
If it is not possible to comply with the above and access is only available from one side of the trailer then the
instruction handbook shall detail the restriction of use, see 8.2.1 (26).
Signs, complying with the requirements of 8.3, shall be fixed at each egress point to warn personnel of the
dangers from passing traffic.
A device for restricting egress from the side of the trailer open to rail traffic shall be provided to prevent people
leaving the trailer on the side open to traffic by mistake. Where possible this shall require the operator to carry
out an intentional action to leave the trailer.
Where doors are fitted they shall:
 be maintained in the fully open and closed positions by automatic latches suitable for the foreseen forces.
It shall be possible to lift the latches by means of the inside and outside handles;
 not project beyond the loading gauge when open;
 make opening quickly and easily possible by th
