Railway applications - Aerodynamics - Part 4: Requirements and assessment procedures for aerodynamics on open track

This document establishes requirements, test procedures, assessment methods and acceptance criteria for operating rolling stock in open track. For pressure variations and slipstream effects beside the track, requirements and assessment methods are provided. For running resistance, assessment methods are addressed in this document. Load cases on infrastructure components due to train-induced pressure variations and slipstream effects are addressed in this document. For ballasted track test set-ups for ballast projection assessment are proposed.
The requirements only apply to rolling stock of the heavy rail system with maximum train speeds above 160 km/h and not to other rail systems. The document is applicable to all rolling stock and infrastructure in open air with nominal track gauges of 1 435 mm to 1 668 mm inclusive.

Bahnanwendungen - Aerodynamik - Teil 4: Anforderungen und Bewertungsverfahren für Aerodynamik auf offener Strecke

Dieses Dokument legt Anforderungen, Prüfverfahren, Beurteilungsverfahren und Abnahmekriterien für den Betrieb von Schienenfahrzeugen auf offener Strecke fest. Für Druckänderungen und Strömungseffekte neben dem Gleis werden Anforderungen und Beurteilungsverfahren bereitgestellt. Für den Fahrwiderstand werden Beurteilungsverfahren in diesem Dokument behandelt. Lastfälle auf Infrastrukturkomponenten aufgrund von zugverursachten Druckänderungen und Strömungseffekten werden in diesem Dokument behandelt. Für Schottergleise werden Prüfaufbauten zur Beurteilung des Schotterflugs empfohlen.
Die Anforderungen gelten nur für Schienenfahrzeuge des Vollbahnsystems mit Höchstgeschwindigkeiten über 160 km/h und nicht für andere Bahnsysteme. Das Dokument gilt für alle Schienenfahrzeuge und Infrastrukturen im Freien mit einer Nennspurweite von 1 435 mm bis einschließlich 1 668 mm.

Applications ferroviaires - Aérodynamique - Partie 4: Exigences et procédures d'évaluation pour l'aérodynamique à l'air libre

Le présent document spécifie les exigences, les procédures d'essai, les méthodes d'évaluation et les critères d'acceptation relatifs aux matériels roulants circulant à l'air libre. Pour les variations de pression et les effets de souffle le long de la voie, des exigences et des méthodes d'évaluation sont fournies. Pour la résistance à l'avancement, les méthodes d'évaluation sont traitées dans le présent document. Les cas de charge pour les composants d'infrastructure dus aux variations de pression et aux effets de souffle induits par les trains sont traités dans le présent document. Pour l'évaluation des projections de ballast, des configurations d'essai sur voie ballastée sont suggérées.
Les exigences s'appliquent uniquement aux matériels roulants du système ferroviaire conventionnel circulant à des vitesses maximales supérieures à 160 km/h, et non aux autres systèmes ferroviaires. Le présent document s'applique à l'ensemble des matériels roulants et infrastructures à l'air libre dont les écartements de voie nominaux sont compris entre 1 435 mm et 1 668 mm, valeurs extrêmes incluses.
