(Main)Railway Applications - Track - Performance requirements for fastening systems - Part 5: Fastening systems for ballastless track
Railway Applications - Track - Performance requirements for fastening systems - Part 5: Fastening systems for ballastless track
This European Standard is applicable to fastening systems, in categories A –D as specified in EN 13481 1:2012, 3.1 for attaching rails to the uppermost surface of concrete or steel elements in ballastless tracks, including tracks on open deck bridges, and for embedded rails in ballastless tracks, for respective maximum axle loads and minimum curve radii in accordance with Table 1.
Table 1 - Fastening category criteria
Category Max design axle load Min curve radius
kN m
A 130 40
B 180 80
C 260 150
D 260 400
NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
The requirements apply to:
- fastening systems which act on the foot and/or web of the rail including direct fastening systems and indirect fastening systems;
- fastening systems for rail sections included in EN13674-1 (excluding 49E4) or EN13674-4
This standard is not applicable to
- fastening systems for other rail sections
- fastening systems for use on wood or polymer composite sleepers used in ballastless track, performance requirements for which are included in EN13481-3
- rigid fastening systems
This standard is not applicable to fastening systems for other rail sections, rigid fastening systems, special fastening systems used at bolted joints or glued joints or special low clamping force fastenings used to mitigate track-bridge interaction effects.
This standard is for type approval of complete fastening systems. In track forms in which there are rail seat blocks or sleepers mounted in “boots” the concrete element and its resilient support are considered to be parts of the elastic fastening system. If the track form includes floating slabs, (i.e. resiliently supported concrete elements with more than one fastening per rail) those concrete elements and their resilient supports are considered to be parts of the ballastless track and not of the fastening system.
Bahnanwendungen - Oberbau - Leistungsanforderungen für Schienenbefestigungssysteme - Teil 5: Befestigungssysteme für feste Fahrbahn
Dieses Dokument ist anzuwenden für Befestigungssysteme in den Kategorien A bis D, wie in EN 13481 1:2012, 3.1, festgelegt, für die Verwendung zur Befestigung von Schienen auf der Oberfläche von Beton- oder Stahlelementen in Festen Fahrbahnen, einschließlich Gleisen auf Brücken mit offener Fahrbahn und für eingebettete Schienen in Festen Fahrbahnen mit maximalen Auslegungsachslasten und Mindestbogenradien nach Tabelle 1.
Die Anforderungen gelten für:
— Befestigungssysteme, die am Schienenfuß und/oder Schienensteg wirken, einschließlich direkter und indirekter Befestigungssysteme;
— Befestigungssysteme für Schienenprofile nach EN 13674 1 (außer 49E4) oder EN 13674 4.
Dieses Dokument ist nicht anzuwenden für Befestigungssysteme für Holz- oder Polymerverbundschwellen in Festen Fahrbahnen, die in EN 13481 3 enthalten sind.
Dieses Dokument ist nicht anzuwenden für starre Befestigungssysteme, spezielle Befestigungssysteme, die für verschraubte oder geklebte Schienenstöße verwendet werden, oder Spezialbefestigungen mit niedriger Spannkraft, die zur Abschwächung von wechselseitigen Einflüssen von Gleis und Brücke verwendet werden.
Dieses Dokument gilt für die Typzulassung eines kompletten Befestigungssystems. Oberbauformen, bei denen es Schienenblöcke oder in „Schuhen“ (Unterschwellenbesohlung) gelagerte Schwellen gibt, gelten das Betonelement und sein elastisches Auflager als Teile des elastischen Befestigungssystems. Wenn zur Oberbauform Masse-Feder-Systeme (d. h. elastisch gelagerte Betonelemente mit mehr als einer Befestigung je Schiene) gehören, gelten dieses Betonelement und sein elastisches Auflager als Teile der Festen Fahrbahn und nicht des Befestigungssystems.
Applications ferroviaires - Voie - Exigences de performance pour les systèmes de fixation - Partie 5 : Systèmes de fixations pour voies sans ballast
Le présent document est applicable aux systèmes de fixation des catégories A à D spécifiées dans l'EN 13481 1:2012, 3.1, utilisés pour fixer les rails sur la surface supérieure d'éléments en béton ou en acier sur des voies sans ballast, y compris sur des ponts à tablier à l'air libre, et pour les rails enrobés dans des voies sans ballast, avec des charges à l'essieu maximales et des rayons de courbure minimaux respectifs selon le Tableau 1.
[Tableau 1]
Les exigences s'appliquent :
- aux systèmes de fixation qui agissent sur le patin et/ou l'âme du rail, y compris les systèmes de fixation directs et les systèmes avec selle ;
- aux systèmes de fixation pour les profils de rail décrits dans l'EN 13674 1 (à l'exclusion du profil 49E4) et l'EN 13674 4.
Le présent document ne s'applique pas :
- aux systèmes de fixation destinés à d'autres profils de rail ;
- aux systèmes de fixation destinés à être utilisés sur des traverses en composite à matrice polymère employées en voie ballastée, pour lesquels les exigences de performance sont spécifiées dans l'EN 13481 3 ;
- aux systèmes de fixation rigides.
Le présent document ne s'applique pas aux systèmes de fixation destinés à d'autres profils de rail, aux systèmes de fixation rigides, aux systèmes de fixation spéciaux utilisés au droit des éclisses ou aux fixations par effort d'application au patin du rail utilisées pour limiter les effets liés à l'interaction voie-pont.
Le présent document est destiné à l'homologation de type de systèmes de fixation complets. Pour les formes de voie intégrant des tables d'appui ou des traverses montées en « chaussons », l'élément en béton et son support élastiques sont assimilés à des parties du système de fixation. Si la forme de voie intègre des dalles flottantes (c'est-à-dire des éléments en béton soutenus de manière élastique avec plusieurs fixations par rail), ces éléments en béton et leurs supports élastiques sont assimilés à des parties de la voie sans ballast et non à des parties du système de fixation.

Category Maximum design axle load Minimum curve radius
kN m
A 130 40
B 180 80
C 260 150
D 260 400
NOTE The maximum axle load for Categories A and B does not apply to maintenance vehicles.
The requirements apply to:
— fastening systems which act on the foot and/or web of the rail including direct fastening systems and
indirect fastening systems;
— fastening systems for rail sections included in EN 13674-1 (excluding 49E4), or EN 13674-4.
This document is not applicable to fastening systems for wood or polymer composite sleepers used in
ballastless track, which are included in EN 13481-3.
This document is not applicable to rigid fastening systems, special fastening systems used at bolted joints
or glued joints or special low clamping force fastenings used to mitigate track-bridge interaction effects.
This document is for type approval of complete fastening systems. In track forms in which there are rail
seat blocks or sleepers mounted in “boots” (under-sleeper pads) the concrete element and its resilient
support are considered to be parts of the elastic fastening system. If the track form includes floating slabs,
(i.e. resiliently supported concrete elements with more than one fastening per rail) those concrete
elements and their resilient supports are considered to be parts of the ballastless track and not of the
fastening system.

5 Requirements determined by laboratory testing
5.1 Specimens used for laboratory testing
The laboratory tests described in 5.2 to 5.5 and 5.7 shall be carried out using a supporting element e.g. a
reinforced concrete block to represent concrete ballastless track or a steel plate to represent a steel
bridge structure.
For continuously supported rail, the test length of rail is the length which is supported on the pad. For
embedded rail, the test length of rail is the length which is embedded. In these cases, for category A the
test length should be (0,8 ± 0,01) m and for categories B to D the test length should be (0,6 ± 0,01) m.
The supporting element shall have a rail seat inclination no greater than the inclination to be used on the
application for which the type of fastening will be used.
For example, a fastening tested successfully on a support with 1:40 inclination does not need to be re-
tested at 1:20 inclination.

Introduction
A series of tests is used to assess the suitability of fastening systems for use in railway track i.e. for type
approval of complete fastening systems. This document only sets requirements considered relevant to
ensure the safe, long term operation of the track system. The test methods are described in other
associated standards.
The various Categories of rail fastenings used in this standard are defined in EN 13481-1:2012.

1 Scope
This document is applicable to fastening systems, in categories A –D as specified in EN 13481-1:2012,
3.1 for attaching rails to the uppermost surface of concrete or steel elements in ballastless tracks,
including tracks on open deck bridges, and for embedded rails in ballastless tracks, for respective
maximum axle loads and minimum curve radii in accordance with Table 1.
Table 1 — Fastening category criteria
Category Maximum design axle load Minimum curve radius
kN m
A 130 40
B 180 80
C 260 150
D 260 400
NOTE The maximum axle load for Categories A and B does not apply to maintenance
vehicles.
The requirements apply to:
− fastening systems which act on the foot and/or web of the rail including direct fastening systems
and indirect fastening systems;
− fastening systems for rail sections included in EN 13674-1 (excluding 49E4) or EN 13674-4.
This document is not applicable to:
− fastening systems for other rail sections
− fastening systems for use on wood or polymer composite sleepers used in ballastless track,
performance requirements for which are included in EN 13481-3
− rigid fastening systems
This document is not applicable to fastening systems for other rail sections, rigid fastening systems,
special fastening systems used at bolted joints or glued joints or special low clamping force fastenings
used to mitigate track-bridge interaction effects.
This document is for type approval of complete fastening systems. In track forms in which there are rail
seat blocks or sleepers mounted in “boots” the concrete element and its resilient support are
considered to be parts of the elastic fastening system. If the track form includes floating slabs, (i.e.
resiliently supported concrete elements with more than one fastening per rail) those concrete elements
and their resilient supports are considered to be parts of the ballastless track and not of the fastening
system.

5 Requirements determined by laboratory testing
5.1 Specimens used for laboratory testing
The laboratory tests described in 5.2 to 5.4 and 5.6 shall be carried out using a supporting element e,g, a
reinforced concrete block to represent concrete ballastless track or a steel plate to represent a steel
bridge structure.
For continuously supported rail, the length of rail used for category A should be (0,8 ± 0,01) m. The test
lengths for categories B to D should be (0,6 ± 0,01) m.
The supporting element shall have a rail seat inclination no greater than the inclination to be used on
the application for which the type of fastening will be used.
NOTE: On this basis a fastening tested successfully on a support with 1:40 inclination does not need to be re-
tested at 1:20 inclination.
For the laboratory test described in 5.5 two fastenings shall be assembled on a section of concrete track
or steel structure with a length equivalent to the intended fastener spacing as described in
EN 13146-5:2012.
For the laboratory test described in 5.7 a fastening system shall be assembled on a concrete block or
steel element as described in EN 13146-10:2017.
5.2 Longitudinal rail restraint or longitudinal stiffness
The requirement for longitudinal rail restraint is included to control rail creep and pull apart in the
event of a broken rail.
For discrete fastening systems, the longitudinal rail restraint shall be not less than 7,0 kN when
measured by the procedure in EN 13146-1:2019 before any repeated load test is carried out. For
fastenings to be used in lines with trains operating at speeds above 250 km/h, the longitudinal rail
restraint shall be not less than 9,0 kN when measured by the procedure in EN 13146-1:2019 before any
repeated load test is carried out.
For embedded rail with an adhesive fastening system, the longitudinal stiffness k shall be measured in
L
accordance with EN 13146-1:2019, between 0 mm and 7 mm (i.e. D = 7) relative displacement per
r
equivalent length of support without visible damage.
On structures such as long bridges, the longitudinal force transmitted between the track and the
structure may be calculated by the method described in CEN/TR 17231:2018 and used in
EN 1991-2:2003/AC:2010. The value of F measured in accordance with EN 13146-1:2019 may be
max
used in the calculation. In such cases and subject to agreement between the purchaser and
manufacturer, the minimum requirement for longitudinal restraint may be reduced.
5.3 Clamping Force and uplift stiffness
This shall be determined by the procedure in EN 13146-7:2019. The result shall be reported.
If the rail fastening system is to be used on long bridge structures calculations of track-bridge
interaction effects at bridge deck ends, such as those required in EN 1991-2:2003/AC:2010, may
require values of uplift stiffness of th
