Overview

prEN 15954-1 - "Railway applications - Track - Trailers and associated equipment - Part 1: Technical requirements for running and working" is a CEN draft European Standard that defines the technical requirements to minimize railway-specific hazards from trailers and their associated equipment during commissioning, operation and maintenance.
This standard applies to trailers that do not operate signalling or control systems and complements Part 2 (general safety / manufacturer declaration). It supports procurement and safety compliance across European track maintenance operations and helps infrastructure managers set authorised running conditions.

Key topics and technical requirements

The standard covers a wide range of railway-specific safety and technical issues, including:

• Trailer categorisation and applicability (including treatment of multiple trailers fixed together as a single system)
• Gauge and running/working limits, including lateral and vertical clearance rules and special limits for narrow/broad gauges, tramways, non‑adhesion systems and underground lines
• Interaction with infrastructure: wheel/rail interaction, auxiliary wheels and guides, loads on ballast and formation, and forces on structures
• Running safety and derailment prevention: equipment, speed-related requirements (e.g. different criteria above and below 60 km/h), and mandatory track tests
• Stability, frame strength and structural requirements, including lifting/jacking points for recovery operations
• Couplings and buffing/draw gear: technical details provided in informative annexes
• Running gear and suspension: wheelset distribution, wheel profiles and axle load configurations
• Braking, driving/working cabs, controls and visibility (lighting, marker lights, tail lamps, lamp brackets and colour)
• Electrical safety and EMC: equipotential bonding, antennae, pantograph considerations and electromagnetic compatibility
• Operational procedures: setting up, packing away, on/off tracking, use of turntables, MEWPs and excavators used as MEWPs
• Marking, numbering, user information and conformity verification, including checklists, certificates and trailer identification plate formats (normative annexes)

Practical applications and users

prEN 15954-1 is practical for:

• Trailer manufacturers (design, type approval and technical documentation)
• Infrastructure managers (authorising running areas and special conditions)
• Maintenance contractors and track-work teams (safe operation, selection and on-track procedures)
• Notified/authorized bodies and test laboratories (type approval, conformity checks and verification)
• Procurement officers specifying compliance in tender documents for track maintenance equipment

Use this standard to create procurement specs, prepare conformity dossiers, design trailer running gear for safe interaction with track infrastructure, and to define operational limits and safety measures.

Related standards

• prEN 15954 consists of Part 1 (this document) and Part 2 (general safety / manufacturer declaration).
• Annex G lists other European Standards covering similar track construction and maintenance machines.
• The standard was developed by CEN/TC 256 and supports relevant EU procurement and safety directives (see Directive 2004/17/EC).

Introduction
The machinery concerned and the extent to which hazards, hazardous situation and events are covered are
indicated in the scope of this document.
This European Standard was prepared to meet the basic requirements of EU Directives to facilitate an open
market for goods and services.
Trailers as specified in 3.1 form the object of this standard.
This standard deals with railway specific risks of the trailers, defined in clause 4, when running and working on
railway infrastructures.
The safety requirements in relation to the Machinery Directive are dealt with in prEN xxxyy-2 of this series of
standards.
Deviations or special national conditions are dealt with in Annex B.
The risks which exist in all mechanical, electrical, hydraulic, pneumatic and other components of trailers and
which are dealt with in the relevant European Standards are not within the scope of this European Standard. If
necessary, references are made to appropriate standards of this type.
1 Scope
1.1 General
This European Standard deals with the technical requirements to minimize the specific railway hazards of
trailers and associated equipment, which can arise during the commissioning, the operation and the
maintenance of trailers when carried out in accordance with the specification given by the manufacturer or his
authorized representative. This European Standards 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 G.
Note Machines not intended for operating signalling and control systems are only permitted to run under special
conditions and within areas specifically designated by the infrastructure manager.
Part 1 of this European Standard deals with requirements for approval of the trailer by an authorized body,
part 2 deals with requirements for the trailer to be declared conformant by the manufacturer, except in the
case of trailers classified in Annex 4 of the Machinery Directive which require conformity check in conjunction
with a notified body.
Additional requirements can apply for running on infrastructures with narrow gauge or broad gauge lines, lines
of tramways, railways utilizing other than adhesion between the rail and rail wheels, and underground
infrastructures.
This European Standard is also applicable for trailers and associated equipment that in working configuration
are partly supported on the ballast or the formation.
Where two or more trailers are used together to transport loads in a fixed formation, e.g. where a metal
container is fixed to two small trailers, the whole system shall be treated as a trailer and comply with the
requirements of this European Standard.
This European Standard does not apply to the following:
 requirements for quality of the work or performance of the trailer;
 specific requirements established by the railway infrastructure operator for the use of trailers,
which will be the subject of negotiation between the manufacturer and the operator;
 separate machines temporarily mounted on the trailer.
This European Standard 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 etc.;
 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 environment, tropical environment, contaminating environments, strong magnetic
fields;
 hazards due to errors in software;
 hazards occurring when used to handle suspended loads which may swing freely.
NOTE The intended use of these trailers may have operational parameters specified by each infrastructure manager,
for example the maximum speed allowed for these trailers is likely to be limited by the infrastructure manager
– compliance with the clauses of this standard does not confer permission for trailers to travel at this speed.
These trailers will not be allowed on a track open to normal railway traffic.
Other track construction and maintenance machines used on railway tracks are dealt with in other European
Standards, see Annex G.
1.2 Validity of this European Standard
This European Standard applies to all trailers, which are ordered one year after the publication date by CEN of
this standard.

5 Railway specific safety requirements and/ or measures
Trailers shall comply with the safety requirements and/ or protective measures in accordance with Clause 5
and 6, and supplied with information in accordance with clause 7. Trailers shall be designed to work on
working track within the geometric limits, see EN 14033-2:2008, Annex F and shall be designed to work on
operating track.
Trailers that can only work on operating tracks shall display on the identification plate an indication of that
restriction, see prEN 14033-1:2008, Annex C.
5.1 Gauge
5.1.1 Running gauge
5.1.1.1 General
Except as shown in 5.1.1.2 trailers in running configuration shall meet the dimensional requirements of
prEN 15273-2. The critical points near the limits of the permissible kinematic gauge, see prEN 14033-1:2008,
Annex C shall be recorded in the technical documentation shown in clause 7.

5.1.1.2 Special cases
Trailers intended to travel on infrastructures with more restrictive gauges shall conform to the specific rules of
those infrastructures and the corresponding restrictions shall be indicated on their operating permits.
For road-rail trailers in the lower area, deviations are permitted to accommodate road wheels, as shown in
Figure 6. The requirement is that the machine does not damage the infrastructure.
NOTE Special national conditions may apply to this exceedance amount, see Annex A.
Key
A = Rail level
B = Exceedance of gauge permitted for road-rail machines
C = Additional exceedance of gauge permitted for category 9 C machines
D = Gauge according to prEN 15273-2:2005

Figure 6 — Limits in lower area

5.1.2 Trailer in running configuration
5.1.2.1 Stowing of moveable trailer parts in running configuration
When the trailer is in the running configuration any movable equipment which has the capacity to go outside
the gauge shall be capable of being stowed in a manner which prevents inadvertent or unintended movement
out of the gauge. All such moveable parts and assemblies forming part of the trailer that are unpacked in order
to allow the trailer to work in rail and non-rail configuration shall, in their stowed state, be secured by devices
capable of resisting the foreseeable forces encountered during running, which shall not rely upon a power
source to retain the locking function. Moveable parts shall be held by either:
 held by efficient locks The visible positive locking elements locking components in running configuration
shall be painted in red. If the locking mechanism is powered the control of locking should preferably be
possible from inside the machine gauge
or
 held by check valves on hydraulic systems which shall prevent movement and fail safe.
It shall be obvious to anyone checking the trailer that these parts of the trailer are locked in their stowed
position.
5.1.2.2 Operating controls in running configuration
When in running configuration all operating controls not related to running, including locking devices, shall be
deactivated.
5.1.3 Working limit general
5.1.3.1 Interference of gauge
Trailers and their moveable component parts shall be designed and built to work without unintentional
interference with the kinematic envelope necessary for the running of trailers admitted by the infrastructure
owner without running restrictions on the operating track. For the different zones of work and the zone limit
between the working track and the adjacent operating track in service, see EN 14033-2:2008, 5.3.
Where the clearance, under worst operating conditions, between the underside of a revolving superstructure
and rail level, is less than 1300 mm this shall be recorded in the instruction handbook, see 7 a) 3) ii).
NOTE The clearance of 1 300 mm is required to enable the superstructure to slew over adjacent track side structures,
platforms etc. Other distances may be required by some infrastructure managers.
Where a trailer has powered moveable components capable of exceeding the kinematic envelope, e. g. a
MEWP basket, there shall be a means of direct communication between the operating position on the trailer
and the driving position of any towing machine.
5.1.3.2 Movement limiting devices
5.1.3.2.1 General
Where operation of any component or general attachment fitted to the trailer exceeds the working limit
according to 5.1.3 the accidental intrusion into the kinematic envelope of the line open to traffic shall be made
impossible by means of lateral and height limiting devices. The limiting devices are to provide protection
against exceedance of the gauge shown in 5.1.1.
Operation of movement limiting devices shall be by key switch or equivalent lock.
The movement limiting devices shall be described with indication of their type and their configuration of
operation in the instruction handbook, see clause 7.

5.1.3.2.2 Design of movement limiting devices
5.1.3.2.2.1 General
Movement limiting devices shall permit the height and rotation limit to be variable to suit each location. The
movement limiting device shall stop the movement when height and lateral limits are reached, or prevent
movement commencing in an unsafe direction if the machine is stopped at its limit. All movement limiting
devices shall comply with 5.1.3.2.2.2 or 5.1.3.2.2.3 or 5.1.3.2.2.4, as appropriate.
5.1.3.2.2.2 Mechanical limiting devices
These devices shall be capable of resisting the foreseeable forces encountered.
NOTE This includes resisting static forces (start-up force of the motion) where they are in the form of a lock, and
dynamic forces where they are in the form of a stop.
5.1.3.2.2.3 Electric limiting devices
The design shall be such that there shall be no credible single point failure that would cause the system to fail
unsafe, i.e. allow the corresponding movement to continue. Any fault, including unacceptable differences in
signals, shall cause the system to fail to a safe condition.
Safety switches acting as information-giving components shall fulfil the requirements as specified in EN 60947
series, or as an alternative to these safety switches, sensors or switches may be used under the following
conditions, shown in order of preference:
c) Using sensors or other types of switch duplicated. They shall either be self-verifying at start-up or shall
have continuous monitoring of the signals from the sensors or switches for out-of-range
or
d) using an arrangement of a single sensor or switch, provided there is a permanent monitoring of the
plausibility of its signals by means of other sensors or switches not of the same safety device.
5.1.3.2.2.4 Hydraulic limiting devices
Hydraulic limiting devices shall be designed and installed to provide safety levels equivalent to those for
electrical safety devices.
Any credible hydraulic fault shall cause the system to fail to a safe condition, i. e. stop the corresponding
movement.
