0 Introduction
This document is a type C standard as stated in EN ISO 12100-1 and EN ISO 12100-2.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When the provisions of this type C standard are different from those which are stated in type A or 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.
Because the EU Directive “Machines” does not consider railway specific problems of construction and maintenance
machines, additional requirements and verifications are necessary and these are dealt with in this document (see
6.2). Portable machines and trolleys for track construction and maintenance, which comply with these
requirements, receive a special marking in accordance with 6.5.3, in addition to the CE mark.
Technical characteristics, deviations or special national conditions will be the subject of special requirements of the
infrastructure manager controller and/or negotiation between the user and the manufacturer, see annex G.
1 Scope
1.1 General
This document deals with the technical requirements to minimise the railway specific significant hazards of portable
machines and trolleys used for work on tracks as listed in clause 4 and annex A which can arise during the
commissioning, the operation and the maintenance of portable machines and trolleys when used as intended and
under the conditions foreseen by the manufacturer. It does not deal with the general function of the machines (e.g.
cutting, drilling, grinding).
This document applies to portable machines and portable trolleys designed for work on the track with nominal track
gauges of 1 435 mm and 1 668 mm and clearance gauge as defined in annex B including cutting machines and
those designed for working on wooden sleepers.
This document does not apply to portable trolleys coupled together, whether or not self propelled, and trolleys used
for transporting personnel.
For portable machines and trolleys used on railway lines with a different clearance gauge to that defined in

1)
annex B specific requirements concerning the clearance gauge may apply .
This document does not apply to the following:
 requirements for quality of the work or performance of the machine;
 regulations defined by each infrastructure controller for portable machine and trolley operation which shall
be the subject of negotiation between the user and the manufacturer;
 portable machines used from railway vehicles.
This document does not establish the additional requirements for the following:
 operation in severe conditions (e.g. extreme environmental conditions such as: freezing applications, high
temperatures, corrosive environment, tropical environment, contaminating environments, strong magnetic
fields);
 operation subject to special rules as potentially explosive atmospheres;
 electromagnetic compatibility, due to e.g. electronic components;
 hazards occurring during decommissioning and/or recycling;
 hazards due to vibration;
 hazards due to wind speed greater than 35 m/s;
 hazards due to natural causes e.g. earthquake, lightning, flooding etc.
 noise.
NOTE Noise of machines which are dealt with by this document is regarded as a significant hazard. Noiseis not covered by
this document but will be dealt with in an Amendment to the first edition of this standard. This Amendment will give:
 clauses dealing with noise emission according to EN 1746.
 a noise test code using as a basis for preparation the designation of noise-emission according to the requirements of
the Machinery-Directive 98/37/EC, annex I, clause 1.7.4f.
