Bahnanwendungen - Oberbau - Linienführung in Gleisen - Spurweiten 1 435 mm und größer - Teil 1: Durchgehendes Hauptgleis
Diese Europäische Norm legt die Regeln und Grenzen für die erlaubten Geschwindigkeiten für eine vorgegebene Linienführung fest. Alternativ für eine bestimmte erlaubte Geschwindigkeit, sind Grenzen für die Konstruktionsparameter für die Linienführung festgelegt.
Weitere restriktive Anforderungen nach den TSI und nach geeigneten lokalen Normen müssen angewendet werden.
Unnötige Anwendung der maximalen (oder minimalen) Grenzwerte nach dieser Europäischen Norm sollte vermieden werden. Eine umfangreiche Toleranz dieser sollte jedoch vorgesehen werden, entweder in Übereinstimmung mit den empfohlenen Grenzwerten oder bei Anwendung einer Toleranz im Hinblick auf die erlaubte Geschwindigkeit.
Diese Europäische Norm gilt für Hauptstrecken mit Spurweiten von 1 435 mm und größer, mit erlaubten Geschwindigkeiten von 80 km/h bis 300 km/h. Anhang C (informativ) beschreibt die Regeln für die Umrechnung, die bei Gleisen mit Spurweiten von mehr als 1 435 mm angewendet werden können. Anhang D besitzt eine verbindliche Bedeutung und ist bei den jeweiligen nationalen Regelungen zu beachten.
Die Werte und Bedingungen für den festgelegten Geschwindigkeitsbereich können auch für Linien mit erlaubten Geschwindigkeiten weniger als 80 km/h angewendet werden; aber in diesem Fall dürfen weiterer oder weniger restriktive Werte angewendet werden und sollten in einem Vertrag festgelegt werden.
Diese Europäische Norm gilt nicht für innerstädtische und Vorortbahnstrecken.
Diese Europäische Norm nimmt auch Bezug auf den Einsatz von Fahrzeugen, die für hohe Überhöhungs¬fehlbeträge ausgelegt sind.
In dieser Europäischen Norm sind bestimmte Anforderungen an Neigetechnikfahrzeuge festgelegt.
Applications ferroviaires - Voies - Paramètres de conception du tracé de la voie - Ecartement 1435 mm et plus large - Partie 1 : Voie courante
La présente Norme européenne définit les règles et limites qui déterminent la vitesse admissible pour un tracé de voie donnée. Réciproquement, elle définit les paramètres de conception du tracé de la voie pour une vitesse admissible donnée.
Des prescriptions plus restrictives faisant l’objet de Spécification Technique d’Intéropérabilité ou de normes nationales appropriées doivent s’appliquer.
Il convient d’éviter une utilisation sans nécessité des valeurs limites maximales (ou minimales) recommandées dans la présente Norme européenne. Il convient de prévoir une marge significative, soit en se conformant aux valeurs limites recommandées, soit en adoptant une marge par rapport à la vitesse admissible.
La présente Norme européenne est applicable aux voies principales d'écartement 1435 mm et plus large, dont les vitesses admissibles sont comprises entre 80 km/h et 300 km/h. L'Annexe C (informative) décrit les règles de conversion qui peuvent être appliquées pour les voies d'écartement supérieur à 1435 mm. L'Annexe D a un caractère normatif et est appliquée pour les conditions nationales particulières correspondantes.
Cependant, les valeurs et les conditions requises pour cette gamme de vitesse peuvent également être appliquées aux lignes dont les vitesses admissibles sont inférieures à 80 km/h, mais dans ce cas, il peut être nécessaire d’utiliser des valeurs plus ou moins restrictives, selon les indications du document contractuel.
Il n’est pas nécessaire d’appliquer la présente Norme européenne à certaines lignes de banlieue et de métro.
La présente Norme européenne prend également en considération la possibilité d’utiliser des véhicules ayant été homologuées pour des insuffisances de dévers élevées.
Pour les trains pendulaires, des exigences particulières sont définies dans la présente Norme européenne.

1 Scope
This European Standard specifies the track alignment design parameters, the rules and the values that shall be
used to determine the maximum operating speed for both new and existing lines. Alternatively, for a given
specified speed, it defines the track alignment design parameters either for a new line or an upgraded line.
The track alignment designer is free to specify the values most appropriate for the various parameters, when
considering safety, geographical, engineering, historical and economic constraints. These values are defined in
the contract document. However, the choice should be such that the selected values are no worse than the
maximum (or minimum) limiting values for the safety-related parameters.
Whenever necessary, the track alignment designer should take into account any specific requirements of the
appropriate national standards.
The designer should endeavour to comply with the recommended limiting values specified in this European
Standard and avoid unnecessary use of the maximum (or minimum) limiting values.
This European Standard applies to main lines with track gauges 1435 mm and wider with mixed or dedicated
passenger traffic, running at operating speeds between 80 km/h and 300 km/h. Annex F (informative) describes
the conversion rules which can be applied for tracks with gauges wider than 1435 mm. Annex G has a
normative character and is applied for corresponding specific national conditions.
However, the values and conditions stated for this speed range can also be applied to lines where operating
speeds are less than 80 km/h, but in this case, more or less restrictive values may need to be used and should
be defined in the contract.
This European Standard does not apply to urban and suburban lines.
This European Standard also considers the possibility of increasing the performance of line operation, without
major alignment modifications, by means of particular rail vehicle types, such as:
vehicles with a low axle mass;
vehicles with a low suspension roll coefficient;
vehicles equipped with tilting body systems to compensate for cant deficiency (active or passive systems).
For tilting trains, certain alignment parameters may prove to be sensitive, depending in particular on the tilt
control system used. Such special requirements and the corresponding limiting values are described, if
necessary, within this part of the European Standard. Annex E draws the attention of the designer to the
consequences of track resistance, stress and fatigue due to the operation of such vehicles.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
3.1
curves
this covers both horizontal and vertical curves and their related transitions. Unless otherwise stated, the curve
parameters are defined for the track centreline
31.1
circular curve
a curve of constant radius
3.1.2
transition curve
a curve of variable radius.
Transition curves may be found between two circular curves, each of a different radius, and between a circular
curve and a straight. The clothoid (or cubic parabola) is normally used for transition curves, giving a linear
variation of curvature and cant. In some cases, cant and or curvature is smoothed at the ends of the transition.
It is possible to use other forms of transition curve which show a non-linear variation of curvature and cant.
In principle, a transition curve is not used for the vertical alignment.
Annex A gives a detailed account of the alternative types of transitions that may be used in track alignment
design
3.1.3
compound curve
a curve formed by two circular curves of different radii which curve in the same direction.
The two adjacent curves may be joined by a transition curve
3.1.4
reverse curve
a curve formed by two circular curves which curve in the opposite direction.
The two adjacent curves may be joined by a transition curve
3.2
cant
the amount by which one gauge rail is raised above the other gauge rail.
Cant is positive when the outer rail on curved track is raised above the inner rail and is negative when the
inner rail on curved track is raised above the outer rail.
Negative cant is unavoidable at switches and crossings on a canted main line where the turnout is curving in
the opposite direction to the main line and, in certain cases, on the plain line immediately adjoining a turnout
(see prEN 13803-2).
When the speed of a vehicle negotiating a curve is such that the resultant of the gravitational force of the vehicle
and the effect of centrifugal force is perpendicular to the plane of the rails, the vehicle is not subjected to
unbalanced lateral force and is said to be in equilibrium. Obtaining this condition on curved track implies raising
one gauge rail above the level of the other gauge rail by a designed amount. This amount is known as the
equilibrium cant
7
---------------------- Page: 8 ----------------------
prEN 13803-1:2006 (E)
3.3
cant excess
when the arranged cant is higher than equilibrium cant, there will be an unbalanced lateral force. The resultant
force will move towards the inner rail of the curve. The difference between arranged cant and equilibrium cant is
known as cant excess. Cant on a straight track results in cant excess, generating a force towards the low rail
3.4
cant deficiency
when the arranged cant is lower than equilibrium cant, there will be an unbalanced lateral force. The resultant
force will move towards the outer rail of the curve. The difference between equilibrium cant and arranged cant is
known as cant deficiency
3.5
cant gradient
the amount by which the cant is increased or decreased in a given transition length
3.6
rate of change of cant
the rate at which cant is increased or decreased relative to the speed of a vehicle negotiating a transition curve,
for example 35 mm per second means that a vehicle travelling at the specified speed will experience a change
in cant of 35 mm in each second
3.7
rate of change of cant deficiency
the rate at which cant deficiency is increased or decreased relative to the speed of a vehicle negotiating a
transition curve, for example 35 mm per second means that a vehicle travelling at the specified speed permitted
will experience a change in cant deficiency of 35 mm in each second
3.8
maximum permissible speed
maximum speed permitted on a curve with associated transitions when radius, cant, cant deficiency and rates of
change of cant and cant deficiency and other parameters have been taken into consideration
3.9
line speed
maximum speed at which vehicles are allowed to run on a line or branch or on sections of a line or branch.
The line speed limit is usually established after taking into consideration the incidence of permanent speed
restrictions on the line or branch. On mixed traffic lines, several different line speed limits may exist at the same
time due to the different types of traffic categories
3.10
recommended limiting values
values to be applied by the designer for the design of new railway lines or sections of such lines, or for the
upgrading of existing lines. Such values ensure maintenance costs of the track are kept at a reasonable level,
except where particular conditions of poor track stability may occur, without compromising passenger comfort
3.11
maximum (or minimum) limiting values
extreme but permissible values used at maximum speed for most railway vehicles. As these values are extreme,
it is essential that the use of maximum (or minimum) limiting values is as infrequent as possible on any given
line.
Annex H describes the constraints and risks associated with the use of maximum (or minimum) limiting values
