Railway applications - Track - Performance requirements for fastening systems - Part 6: Special fastening systems for attenuation of vibration
This European Prestandard specifies requirements for the performance of fastening systems for attaching rails to sleepers or longitudinal bearers or in non-ballasted track to the uppermost surface of concrete or asphalt slabs. It applies to track with a minimum curve radius greater than 40 m and subject to a maximum design axle load of 260 kN. It does not apply to embedded rails.
The requirements apply to direct fastening systems and systems which incorporate a baseplate. They are not applicable to systems which incorporate concrete elements or other high mass elements nor to special fastening systems used at bolted rail joints.
This European Prestandard is for type approval only.

This European Prestandard (ENV) was approved by CEN on 28 December 2000 as a prospective standard for provisional application.
The period of validity of this ENV is limited initially to three years. After two years the members of CEN will be requested to submit their
comments, particularly on the question whether the ENV can be converted into a European Standard.
CEN members are required to announce the existence of this ENV in the same way as for an EN and to make the ENV available promptly
at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in parallel to the ENV) until the final
decision about the possible conversion of the ENV into an EN is reached.
CEN members are the national standards bodies of Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece,
Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Introduction
This European Prestandard was originally drafted as a European Standard but it was decided that the state of the
art would not permit publication as a full Standard. It is intended to review this Prestandard two or three years after
publication when there should be sufficient experience and data available to permit a full Standard to be prepared.
A requirement for longitudinal rail restraint is included to control rail creep and pull apart in the event of a broken
rail. The relationship between longitudinal rail restraint and the overall design of the track slab requires
consideration.
A class of high attenuation of dynamic loading is included for use when it is necessary to protect the track from
vehicle induced impacts.
The laboratory test for the effect of repeated loading is the means of assessing potential long term performance of
the fastening in track
For systems in which the rail is continuously supported, test procedures are modified to take account of the change
from discrete support.
The attenuation of vibration achieved by fastening systems depends on the foundation impedance and transient
load conditions which may vary in situ. For the purposes of this European Prestandard it is assumed that the
stationary vertical vibration is adequate to characterize the performance of fastening systems in respect of
attenuation of vibration. Two test procedures, direct and indirect, are included as it is known that the apparatus for
both procedures is in use. It is intended to include only one test procedure when this Prestandard is replaced by a
full Standard.
Some fastening systems utilise concrete elements, such as booted sleepers, to contribute to their overall vibration
attenuation. The procedure for measuring attenuation of vibration is not applicable to such fastening systems.
1 Scope
This European Prestandard specifies requirements for the performance of fastening systems for attaching rails to
sleepers or longitudinal bearers or in non-ballasted track to the uppermost surface of concrete or asphalt slabs. It
applies to track with a minimum curve radius greater than 40 m and subject to a maximum design axle load
of 260 kN. It does not apply to embedded rails.
The requirements apply to direct fastening systems and systems which incorporate a baseplate. They are not
applicable to systems which incorporate concrete elements or other high mass elements nor to special fastening
systems used at bolted rail joints.
This European Prestandard is for type approval only.
