Aerodynamics
Standardization of aerodynamical requirements and test methods for running in tunnels and on plain track for the safety of passengers and crew.
General Information
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.

This document gives guidelines for the cross wind assessment of railways.
This document is applicable to all passenger vehicles, locomotives and power cars (with a maximum train speed above 140 km/h up to 360 km/h) and freight wagons (with a maximum train speed above 80 km/h up to 160 km/h) and track gauges from 1 435 mm to 1 668 mm inclusive. For passenger vehicles, locomotives and power cars with a maximum train speed between 250 km/h and 360 km/h, a requirement to demonstrate the cross wind stability is imposed. This document is not applicable to light rail and urban rail vehicles.

This document establishes requirements, test procedures, assessment methods and acceptance criteria for aerodynamics in tunnels and rolling stock in tunnels. Topics of aerodynamic pressures and loadings, aerodynamic resistance and micro-pressure waves are addressed.
Requirements for rolling stock with operating speeds equal to or above 200 km/h are provided for pressures generated in tunnel operation. Requirements for infrastructure with design speeds above 160 km/h or high blockage ratio or tunnels longer than 12 km are provided for pressures generated in tunnel operation. These requirements are not applicable to light rail and urban rail.
This document is applicable to all railway vehicles and infrastructure with track gauges from 1 435 mm to 1 668 mm inclusive.
